RE: [xsl] Change text on given node at runtime

[Mukul Gandhi <mukulw3@xxxxxxxxx>]

Hi Jeff,
  i tried to solve your problem. Below is the complete
XSL and XML(i have assumed an example XML). Please let
me know if my stylesheet works with your actual XML.
Since you are using Xalan-J, i have used a Xalan
extension function nodeset which helps me enumerate
over the attributes.

Sample XML
----------
<?xml version="1.0" encoding="UTF-8"?>
<rootelem>
<A id="1" name="name1">aaa</A>
<B id="2" name="name2">bbb</B>
<C id="3" name="name3">ccc</C>
<D id="4" name="name4">ddd</D>
<E id="5" name="name5">eee</E>
<F id="6" name="name6">fff</F>
<G id="7" name="name7">ggg</G>
<H id="8" name="name8">hhh</H>
</rootelem>

XSL
---

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:xalan="http://xml.apache.org/xalan";
exclude-result-prefixes="xalan">
<xsl:output method="xml" version="1.0"
encoding="UTF-8" indent="yes"/>

<xsl:param name="tag"/>
<xsl:param name="text"/>
	
<xsl:template match="@* | node()">
   <xsl:if test="(name(.) = $tag)">
     <xsl:element name="{$tag}">
       <xsl:for-each select="xalan:nodeset(@*)">
	<xsl:variable name="attName" select="name(.)"/>
	<xsl:attribute name="{$attName}"><xsl:value-of
select="."/></xsl:attribute>
      </xsl:for-each>
      <xsl:value-of select="$text"/>
     </xsl:element>
   </xsl:if>	     

   <xsl:if test="not(name(.) = $tag)">
     <xsl:copy>
	<xsl:apply-templates select="@* | node()"/>
     </xsl:copy>
   </xsl:if>
</xsl:template>

</xsl:stylesheet>

Regards,
Mukul
