Re: applying templates to attribute value

Ken,

Thanks for your quick reply. In fact, the select statement was what I started out with, but changed it to apply-templates in order to have the content itself match on the <b> and <br />. Doesn't apply templates force further matching of the matched node? Instead I am still getting the attribute value, untransformed.

Here is what I now have with your cyhanges, alongwith the output:
(I am using Altova).

XML: ==================================

<TEAMS_ASSET_FILE>
   <METADATA>
      <UOIS>
         <GT_ASSET_REQUEST_MD COVERLETTER_TEXT="This is a &lt;b&gt;test&lt;/b&gt; of the line break formatting&lt;br /&gt;. Did it work?" />
      </UOIS>
    </METADATA>
</TEAMS_ASSET_FILE>

XSL: ==================================

<xsl:stylesheet version="1.1" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fo="http://www.w3.org/1999/XSL/Format" exclude-result-prefixes="fo">
<xsl:template match="TEAMS_ASSET_FILE">
   <xsl:apply-templates select="METADATA/UOIS/GT_ASSET_REQUEST_MD/@COVERLETTER_TEXT" />
</xsl:template>

<!-- formatting in the block -->
<xsl:template match="GT_ASSET_REQUEST_MD/@COVERLETTER_TEXT">
  <xsl:value-of select="."/>
</xsl:template>
<xsl:template match="br">
  <fo:block> </fo:block>
</xsl:template>
<xsl:template match="b">
  <fo:inline font-weight="bold">
    <xsl:apply-templates />
  </fo:inline>
</xsl:template>

</xsl:stylesheet>

OUTPUT: ===============================

<?xml version="1.0" encoding="UTF-8"?>This is a &lt;b&gt;test&lt;/b&gt; of the line break formatting&lt;br /&gt;. Did it work?
