RE: [Help!] Concatenating @attributes as parts of XSLT apply-temp late tags

[Stuart Roebuck <sr...@adolos.com>]

Joe,

Thanks, just before you replied I managed to get it working by passing the  
string as a parameter to a named template which did the apply-template  
call.  eg.:

  <xsl:template name="pe:macro-select">
   <xsl:apply-templates select="document($file)"/>
  </xsl:template>

called with:

  <xsl:call-template name="pe:macro-select">
   <xsl:with-param name="file">
    <xsl:text>mydirectory/</xsl:text>
    <xsl:value-of select="@file"/>
   </xsl:with-param>
  </xsl:call-template>

But your solutions is an order of magnitude better!


You don't happen to have a similar solution to dealing with a combination  
of filename and XPath where both are passed as attributes.

e.g. trying to do something like:

	<xsl:apply-templates select="document(@file)//@mytag"/>

which doesn't work.  It appears as though the @mytag is being replaced by  
a quoted string.


Thanks again,

Stuart.
