Question

I’m trying to format strings in XSLT that needs to be in pascal case to be used appropriately for the application I’m working with.

For example:

this_text would become ThisText
this_long_text would become ThisLongText

Is it possible to also set this up where I can send an input to the format so I do not have to recreate the format multiple times?

This transformation:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>

 <xsl:variable name="vLower" select=
  "'abcdefghijklmnopqrstuvwxyz'"/>

 <xsl:variable name="vUpper" select=
  "'ABCDEFGHIJKLMNOPQRSTUVWXYZ'"/>

 <xsl:template match="node()|@*">
  <xsl:copy>
   <xsl:apply-templates select="node()|@*"/>
  </xsl:copy>
 </xsl:template>

 <xsl:template match="text()">
  <xsl:call-template name="Pascalize">
   <xsl:with-param name="pText" select="concat(., '_')"/>
  </xsl:call-template>
 </xsl:template>

 <xsl:template name="Pascalize">
  <xsl:param name="pText"/>

  <xsl:if test="$pText">
   <xsl:value-of select=
    "translate(substring($pText,1,1), $vLower, $vUpper)"/>

   <xsl:value-of select="substring-before(substring($pText,2), '_')"/>

   <xsl:call-template name="Pascalize">
     <xsl:with-param name="pText"
       select="substring-after(substring($pText,2), '_')"/>
   </xsl:call-template>
  </xsl:if>
 </xsl:template>
</xsl:stylesheet>

when applied on this XML document:

<t>
  <a>this_text</a>
  <b>this_long_text</b>
</t>

produces the desired result:

<t>
    <a>ThisText</a>
    <b>ThisLongText</b>
</t>

BTW, this is camelCase and this is PascalCase
