Re: [xsl] Version 2.0 Tips and Tricks

["bryan rasmussen" <rasmussen.bryan@xxxxxxxxx>]

in fact if I look in your transformation the point that seems most
likely to be causing it would be if  <xsl:apply-templates
mode="F-chic-auth-date"/> did something to call the copying template
on an attribute somewhere, for example with the following input:

<journals att="x">

<journalcode>CIJB</journalcode>
<ref-govpub>test
</ref-govpub>
</journals>

and the following stylesheet

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version="2.0" xmlns:aid="example.org">
<xsl:output method="xml" encoding="utf-8"/>
   <xsl:template match="@*|node()">
  <xsl:copy>
       <xsl:apply-templates select="@*|node()"/>
  </xsl:copy>
 </xsl:template>

 <xsl:template match="ref-govpub">

<!-- journal Code check  -->

 <xsl:if test="string(//journalcode)='CIJB'">
  <xsl:copy>
 <xsl:attribute name="aid:pstyle">ref</xsl:attribute>
   <xsl:copy-of select="@*"/>
   <xsl:apply-templates select="authorfield"/>
 <xsl:apply-templates select="docpubtitle"/>
 <xsl:apply-templates select="pubnum"/>
 <xsl:apply-templates select="pubfield"/>
<xsl:if test="./chaptitle">
<char><xsl:text>, </xsl:text></char>
   <xsl:apply-templates select="chaptitle"/>
</xsl:if>
   <xsl:if test="./addinfo">
   <xsl:apply-templates select="./addinfo"/>
</xsl:if>
 <xsl:apply-templates mode="F-chic-auth-date"/>
<char><xsl:text>.</xsl:text></char>
  </xsl:copy>
  </xsl:if>
</xsl:template>

<xsl:template match="text()" mode="F-chic-auth-date">
hello
<xsl:apply-templates select="/*/@*"/>
</xsl:template>
</xsl:stylesheet>

which of course gives the error that an attribute node cannot be
created after the child nodes of an element, because F-chic-auth-date
is running in the context of <ref-govpub> which is copied out,
followed by some other elements that are created and closed. After
which the mode is called, and the attribute is attempted to be added
at a place where an attribute cannot be added. Obviously the above is
just an example, but does it sound like anything you are doing in the
rest of your transformation?
