Re: [xsl] Follow path in source-xml according to another source-document

["Mukul Gandhi" <gandhi.mukul@xxxxxxxxx>]

Please try the following stylesheet:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
                       version="1.0">
	
  <xsl:output method="text" />

  <xsl:variable name="largeDoc" select="document('large.xml')" />

  <!-- matches the leaf element -->
  <xsl:template match="*[not(node())]">
    <xsl:variable name="result">
      <xsl:call-template name="getText">
        <xsl:with-param name="largeDoc" select="$largeDoc/*" />
        <xsl:with-param name="elem" select="." />
      </xsl:call-template>
    </xsl:variable>
    <xsl:value-of select="normalize-space($result)" /><xsl:text>&#xa;</xsl:text>
  </xsl:template>

  <xsl:template match="text()" />

  <xsl:template name="getText">
    <xsl:param name="largeDoc" />
    <xsl:param name="elem" />

    <xsl:choose>
      <xsl:when test="(local-name($largeDoc) = local-name($elem)) and
($largeDoc/@id = $elem/@id)">
        <xsl:value-of select="$largeDoc" />
      </xsl:when>
      <xsl:otherwise>
        <xsl:for-each select="$largeDoc/*">
          <xsl:call-template name="getText">
	     <xsl:with-param name="largeDoc" select="." />
	     <xsl:with-param name="elem" select="$elem" />
          </xsl:call-template>
        </xsl:for-each>
      </xsl:otherwise>
    </xsl:choose>
  </xsl:template>

</xsl:stylesheet>

PS: This stylesheet is applied to the "light" input XML. And the other
XML is named as, large.xml.
There are some approximations for the input structure, and also some
redundant processing.
