Recursion reminds me of Recursion (9 XSLT Recursion examples)

Author: David Silverlight Published: 11/25/2005 4:10 PM Category: XML, XSL Summary: This snippet contains 9 examples of common usages of recursion: Iterating through a string of characters, Split(), TrimL(), TrimR(), Loop(), Replace(), LineFeed_To_BR, Min(), Max()

The following samples correspond to the "Shedding a little light on XML" Q&A column for a past XML Journal article on recursion. I coded about half of the examples and included recursion examples from other contributors. Also Note that the download includes an example of how to use Recursion in VB to load a treeview control. Example 1: Iterating through a string of characters. File Description ProcessString.xsl XML XSL Stylesheet which contains the recursive "ProcessString" template ShowProcessString.xsl XSLT Stylesheet used to call the ProcessString template ShowProcessStringOutput.htm Example of the HTML output that will result from transforming ShowProcessString.xml with ShowProcessString.xsl ShowProcessString.xml The XML File containing the string of characters we are converting. ProcessString.zip All files for the ProcessString() template example Example 2: Split() - "Splitting XML elements into smaller XML Elements" File Description ShowSplitOutput.xml XML file used to demonstrate the output from the Split template sample Employees.xml XML Employee data used to demonstrate the Split() template Split.xsl Template used for splitting an element into smaller elements. ShowSplit.xsl XSLT file used to demonstrate the Split() template in action. Split.zip All files for the split() template example Example 3: TrimL() - "Removing the leading spaces from a string" File Description ShowTrimLOutput.htm HTML file used to demonstrate the output from the TrimL template sample Employees.xml XML Employee data used to demonstrate the TrimL template. ShowTrimL.xsl XSLT file used to demonstrate the TrimL template in action TrimL.xsl The TrimL() template used for removing the leading spaces from a string. TrimL.zip All files for the TrimL() template example Example 4: TrimR() - "Removing the trailingspaces from a string" File Description ShowTrimROutput.htm HTML file used to demonstrate the output from the TrimR template sample Employees.xml XML Employee data used to demonstrate the TrimR template. ShowTrimR.xsl XSLT file used to demonstrate the TrimL template in action TrimR.xsl The TrimR() template used for removing the trailing spaces from a string. TrimR.zip All files for the TrimR() template example Example 5: Loop() - "Repeating a string X number of times. Contributed by Ken G. Holman-   File Description Loop.xsl XSLT file used to demonstrate the repeating of a string X number of times. LoopOutput.txt Text file used to demonstrate the output from the Loop template sample Loop.zip All files for the Loop() template example Example 6: Replace() - Using a named template to do substring replacement, contributed Mike J. Brown of Fourthought, Inc  File Description Replace.xsl XSLT file used to demonstrate substring replacement ReplaceOutput.htm HTML file showing the results of the substring replacement Replace.zip All files for the Replace() template example. Example 7: LineFeed_To_BR() - "Transformation of linefeed characters to HTML <br> tags, contributed byMike J. Brown of Fourthought - File Description LF_to_BR.xsl XSLT file used for transforming linefeed characters to <br> tags LF_to_BROutput.htm HTML file used to demonstrate the Linefeed to BR functionality LF_to_BR.zip All files for the LF_to_BR()template example. Example 8: Min() - Finding the minimum element in a nodeset File Description ShowMinOutput.htm HTML file used to demonstrate the output from the Min template sample Min.xsl The Min() template used for finding the minimum value in a nodeset ShowMin.xsl Template used for demonstrating the use of the Min() template Temperatures.xml XML Temperature data used for demonstrating the Min() template Min.zip All files for the Min()template example. Example 9: Max() - "Finding the Maximum element in a nodeset File Description ShowMaxOutput.htm HTML file used to demonstrate the output from the Max()n template sample Max.xsl The Max() template used for finding the maximum value in a nodeset ShowMax.xsl Template used for demonstrating the use of the Max() template Temperatures.xml XML Temperature data used for demonstrating the Max() template Max.zip All files for the Max()template example
