Re: processing text nodes one character at a time

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:template match="/">
 <xsl:call-template name="TransformString">
   <xsl:with-param name="string" select="element" />
 </xsl:call-template>
</xsl:template>

<xsl:template name="TransformString">
 <xsl:param name="string" />

 <xsl:if test="string-length($string) &gt; 0">
   <xsl:text>x</xsl:text><xsl:value-of select="substring($string, 1, 1)" />
   <xsl:call-template name="TransformString">
     <xsl:with-param name="string" select="substring($string, 2)" />
   </xsl:call-template>
 </xsl:if>
</xsl:template>

<?xml version="1.0" encoding="UTF-8"?>
<element>abcd</element>

I am transforming xml data into our type-setters proprietary data
format. I use XSLT 2.0 for the purpose. In special cases, I need to
process text nodes one character at a time: the string must be copied
to the output, but with a code (let's call it "x") inserted before
each character.

Thus, the input: <element>abcd</element>

should lead to the output: "xaxbxcxd"

I think I need some combination of a for-loop and a substring-function
that selects the characters one by one (or maybe this can be solved
using a regex). I just can't get it right... Any suggestions?
