Extracting wordpress posts from xml export file

A variation of the MS Excel spreadsheet, schGoogleToolBox.xls, that I wrote for extracting posts from the Blogger xml export file. This version extracts from the wordpress xml export file, slightly more complicated as uses namespaces and CDATA elements.

The objective was to extract the individual posts from the xml file, then import into Scrivener, unfortunately wordpress does strange things with html paragraph marks.  Also as I am working on MS Windows my html that I wrap the exported data into to create a valid html file, resulted in combined DOS and Unix end of line markers. The wordpress post in the CDATA section contains only linefeed characters (LF) not carriage return (CR) and line feed,  also no paragraph <p> markers, so the files as imported into Scrivener lost paragraph spacing.

To resolve this I was just going to open and convert in UltraEdit Studio but that seemed time consuming for several files, therefore modified the vba code to replace the double LF's with, double CRLF's and double <br>  codes. This produced acceptable paragraph spacing when the html files are imported to Scrivener as and converted to plain text.

The spreadsheet also retrieves categories and tags, and classes these as keywords and counts the frequency of assignment.

It only extracts posts with post_type='post', the vba code can be modified to get static pages, or if have a woocommerce site can extract products.

Spreadsheet can be down loaded: schWordPressToolBox.xls

One eWorkBook a Month

Not actually created at the rate of one a month, but representative of what could be done. Most however were created over a single weekend during the past 25 years or so: some started in As Easy As, and others in QPro. After the initial creation they were then expanded, on an as needs basis.

One eWorkBook a Week

The first 25 not actually created at the rate of one a week, but representative of what could be done. Most however were created over a single weekend during the past 25 years or so: some started in As Easy As, and others in QPro, now all in MS Excel. After the initial creation they were then expanded, on an as needs basis.

This list is a work in progress and I will update as I release the workbooks. {NB: The links on the file names lead to posts with more detail about the workbook. See post link at bottom of page for bundled package. Those without a blog post link can be found on my ExcelCalcs profile}

Today 23/06/2015 is week 26 for 2015, so with the above now upto date with respect to week 26, should now be able to release one workbook per week. Changed my mind [28/6/2015], decided to list all the spreadsheets that I have released already: turns out that exceeds 52 spreadsheets, so the rest will be listed on the one workbook per day challenge.

The workbooks listed below are available via this blog and and some over on MiScion Pty Ltd.

Block of workbooks need to Supply to catch up with current date in 2015, as at 22/6/2015. Assuming 30 days to catch up, that will be around 200 workbooks need to supply in 30 days, or about 7 workbooks per day: which may just be about possible. Otherwise move from calender year to financial tax year 2015 July to 2016 June.

eWorkBook Challenge: spreadsheets and other calculation workbooks

Over past few years noticed several challenges such as a photo a day, a sketch a day, and 500 words a day, some of these challenges are based on a year, others over shorter periods such as a month or week.  A quick search of the internet didn't reveal any similar challenges for spreadsheets or other calculation workbooks such as MathCAD, in the main the challenges are to create an electronic workbook [eWorkBook] for a specific purpose, or otherwise use spreadsheets to track progress with other challenges: such as  tracking progress  writing a 50,000 word novel in a month at an average rate of 1667 words/day. It would therefore seem there is no existing challenge for creating a collection of spreadsheets.

May be such challenge isn't considered appropriate, or it is just too complicated for an individual to pursue. Most people don't have a need for a large variety of spreadsheets, they just produce multiple spreadsheets based on one single template. Those people working in technical fields probably already have the eWorkbooks they need for their work, whilst others create new eWorkbooks everyday in the course of their daily work. However it is also clear that people are looking for technical spreadsheets to carry out various engineering calculations. So there are people who can use eWorkbooks but not build them, or otherwise don't want to put the effort in at the time they need them.

By now I would expect that most graduates from formal educational programmes would have a toolbox of eWorkBooks for the types of tasks they will commonly encounter. Though unfortunately a lot of those they create as a formal part of their courses are probably created in software the likes of MathCAD and/or MatLAB: the problem with such is that such software is expensive and not all that readily available in organisations. Spreadsheets however are a lot more readily available, and therefore the better choice for building a toolbox of calculation tools.

The challenge isn't intended to be a competition with winners and losers, there are no prizes. The challenge is a personal goal, that anyone can take up, the prize if any is a useful personal collection of calculation tools. If wish to share such tools then I recommend up loading them to ExcelCalcs. The challenge can be spread over any time frame, suggestions are:
  1. One eWorkBook a Month (12 for a year)
  2. One eWorkBook a Week (52 for a year)
  3. One eWorkBook a Day (365 for a year)
Which provides the opportunity to spread the challenge over a period of 3 years, the first year starting with one spreadsheet a month, then slowly building up to one spreadsheet a day for the third year.

I have already uploaded 37 unique files to my ExcelCalcs profile, so that represents enough spreadsheets to cover one workbook a month. Given that some of these are zip files, with at least one containing more than 40 workbooks, that also means enough workbooks to cover one workbook a week. Searching my archive hard-drive I find over 70,000 workbooks of various formats (As Easy As, QPro DOS, QPro Windows, MS Excel), many of those are duplicates or minor variations on a theme. My main toolbox already holds over 700 MS Excel spreadsheets. So producing some 365 eWorkBooks doesn't seem an impossible challenge: though creating something unique from scratch each and every day could be challenging. However the challenge doesn't have to be about creating from scratch, for me the challenge would be cleaning up the existing spreadsheets and reformatting so that they are suitable for release for others to use.

eWorkBooks, spreadsheets or otherwise can be classified into the following types:

TYPE 1: Reference Library
These eWorkBooks are databases or tables of data which are largely constant, and used as lookup values for calculations. They include such things as materials libraries, properties of chemical elements and such things. {MS Access or other DBMS potentially the better tool for this}

TYPE 2: Data Collection
These are eWorkBooks that are used to collect variable data, and create data tables and simple lists. Examples would include book lists and price lists. {MS Access or other DBMS potentially the better tool for this.}

TYPE 3: Tabulated Calculations
Tables of independent parameters and calculated dependent variables, with or without charts or graphs illustrating such relationships. {MS Access or other DBMS potentially the better tool for this.}

TYPE 4: Text Book Formula Sheets
These are the type of eWorkBooks typically uploaded to ExcelCalcs and complying with their recommended template making use of XLC. Such worksheets typically restricted to a single A4 page, have a sketch to illustrate the parameters of the mathematical model, show the algebraic formula, show the numbers substituted in the formula and then show the numerical result. These are primarily for the purpose of studying and understanding the formula.

TYPE 5: Calculated Reports
These are full technical reports, at least as far as the calculations go. Simply combining a series of Type-4 spreadsheets would not be appropriate for such reports. Such approach would generate a large amount of paper if so printed, or waste of hard-disk space if printed to pdf files, and most importantly a waste of time to read. Such calculated reports should be kept compact and concise, details of calculations are hidden behind the scenes, the reports display input parameters, and calculated results, but not necessarily the process of transformation from input to result. The user of such reports is expected to make independent checks on the results using other tools.

TYPE 6: Calculators and Dashboards
These can be simple or complex, either way no printed report is generated. These obtain input parameters and calculate results, how such transformation takes place is not shown. The purpose of such tools is rapid decision making. Such tools are likely used by persons checking Type-5 workbooks.

TYPE 7: Applications
These eWorkBooks can make little to extensive use of visual basic for applications (vba) and custom dialogue forms. The main features are that the workbook has the simple interface of Type-6 calculators, but can produce the reports of Type-5, or otherwise more detailed trace similar to Type-4, as well as produce tabulated reports based on variations in magnitude of input parameters similar to Type-3. Also likely to include data collection (Type-2), and rely on information extracted from libraries (Type-1).

TYPE 8: Function Libraries
Libraries of additional functions., which extend or otherwise simplify the calculation capabilities of the primary workbook application (eg, MS Excel).

TYPE 9: Utility Library/Add-In
Extends the features of the primary application (eg.MS Excel), but not the calculation capability. (eg. XLC).

TYPE:10: Other
Those types pf spreadsheets not mentioned elsewhere.

EngineLT revised to Current Wind Code

A revised version of my EngineLT application for estimating size of frames for doubly pitched moment frames, typically used in cold-formed sheds. The orginal version was written in Delphi 3 to AS1170.2:1989, the current version is written in vb.net to AS1170.2:2011. The change in language is because I use MS Excel for day to day calculations, with schTechLIB.xla in the background providing functions for wind loading, steel, cold-formed steel, and timber design. This is written in vba and kept up to date, whilst the Delphi code not kept up to date: to avoid translating languages moved over to vb.net.

The revised version of the code reads an XML data file, this file contains names of structural sections and the resistance to bending (phi.Ms) in units of kNm. The file can be added to if needed, it already contains, Cee's, RHS, SHS, UB, UC, PFC's.

It doesn't contain back to back Cee's, such are not really required. As far as the program is concerned the bay spacing is the load width of the individual portal frame. The load width of a frame can be found by halving the distance to each frame either side of the selected frame and summing. For cold-formed steel sheds with frames at 3m centres the load width of a typical frame is 3m. The load width of the end frame is 1.5m. Often for sheds made from hot rolled steel the typical frames are UB's with the end frames made from PFC's: not always practical has it hinders extending the building, and there is extra detailing merely for two frames. Any case it gives the basic idea, the internal frames can be I-sections formed from back to back Cee's and the end frame can be a single Cee.  Knowing that a single Cee has a load width of 3m, then back to back Cee's form a frame with a total load width of 6m, the back-to-back frames can therefore be placed at 6m centres, whilst a single Cee can be used for the end frame. Therefore check frame for load width of 3m (bayspace = 3m) for a single Cee rather than the back-to-back Cee's at 6m centres.

It is also to be noted that whilst a given section may be structurally strong enough, it may not be practical to make an adequate moment connection between the rafter and column.: such check is not made by the application. Other issues not checked are the deflections of the frame.

The prime purpose of the application is to determine what is not suitable and reject immediately, whilst that considered suitable by the application requires further structural design.

To keep the input form simple, there are many assumptions made in the background. The assessment made by the application will not match my height/span charts as I adopted internal pressure coefficients of -0.65 and +0.7 for this application, but -0.3 and +0.4 for the charts.

I have a larger Engine application, which I am in the process of also translating from Delphi to vb.net and from AS1170.2:1989 to AS1170.2:2011, makes fewer assumptions but has more input screens and requires connection to a database of section properties, it also generates scripts (.scr) for AutoCAD LT. The original purpose of EngineLT was to severe the original programme from the Borland Database Engine (BDE), as it seemed far too complicated setting up on some other computer.

The application can be obtained here: vbEngineLT.zip

Simple Wind Loading Application: Speeds, Pressures and Pressure Coefficients

A simple application for getting wind speeds, pressures and pressure coefficients to AS1170.2 for a rectangular enclosed building with doubly pitched roof. There are two versions in the zip file download. tstwnd.exe and windyworkBench.exe. The former was written in Delphi 3 to AS1170.2:1989, whilst the latter is written in vb.net to AS1170.2:2011.

Application can be down loaded: windWorkBench.zip

Import XML Data to MS Excel

Simple Excel Application which reads the XML file created by earlier application. The data is read into the workbook, and written to a single worksheet. It is also separated into worksheets for parameters, variables, lists and tables. Lists are written across a row. Named ranges are also created for Parameters and Variables.

It doesn't use any XML library to read the file, instead it uses a limited parser written in vba.

Its a simple experimental application showing possibility of exporting and importing parameters to simple XML files, to share data between spreadsheet applications.

Normally I try to create spreadsheets with all parameters on a single worksheet, formatted to be compatible with export to DBase, Paradox and MS Access tables, such worksheet could also be directly exported to XML. However as workbooks grow, not all parameters get referenced on the summary sheet. The two XML workbooks help clean the workbooks up.

Export MS Excel named Ranges to XML

A simple MS Excel application which allows opening another MS Excel workbook and then saves all the named ranges to an XML file.  Whilst Excel permits saving workbook as an XML file, or exporting data to an XML file, such is of little use for data randomly scattered throughout the workbook.

The application exports the data tagged as parameters, variables, lists and tables. If a named range is a single cell and unprotected then it tags it as a parameter. If the single cell is not unprotected then it is tagged as a variable. A named range which consists of a single row or column of data is tagged a list, whilst a named range comprising of rows and columns is tagged a table.

It doesn't use any XML library, it simply writes the data to a simple text file with appropriate tags. Also it uses FileSystem objects to write to the file, as the standard vba print statements do not recognise unicode characters, where as Excel cells can contain such.

Spreadsheet can be down loaded: exportNamedToXML.xls
