Hi,

We have multiple XML files which need to fetch parent elements with
attributes only from one file. Find below my xsl and input files.

ID File: <!-- Take chapter based on the section file -->
<gd id="RB_A">
B  B  B  B  <act id="RB_C">
B  B  B  B  B  B  <title>SET</title>
B  B  B  B  B  B  <body>
B  B  B  B  B  B  B  B  <chap id="RB_CHAP1">
B  B  B  B  B  B  B  B  B  B  <sect id="RB_S1"/>
B  B  B  B  B  B  B  B  B  B  <sect id="RB_S2"/>
B  B  B  B  B  B  B  B  </chap>
B  B  B  B  B  B  B  B  <chap id="RB_CHAP2">
B  B  B  B  B  B  B  B  B  B  <sect id="RB_S3"/>
B  B  B  B  B  B  B  B  B  B  <sect id="RB_S4"/>
B  B  B  B  B  B  B  B  </chap>
B  B  B  B  B  B  </body>
B  B  B  B  </act>
B  B  </gd>
Sect file: <!-- Multiple Section file like this -->
B <sce>
B  B  B  B  <gd id="RB_A">
B  B  B  B  B  B  <act id="RB_C">
B  B  B  B  B  B  B  B  <title>TITLE</title>

B  B  B  B  B  B  B  B  </body>
B  B  B  B  B  B  </act>
B  B  B  B  </gd>
B  B  </sce>
Desired File:
B <sce>
B  B  B  B  <gd id="RB_A">

B  B  B  B  B  B  B  B  </body>
B  B  B  B  B  B  </act>
B  B  B  B  </gd>
B  B  </sce>

XSL:


<xsl:transform version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
B  B  <xsl:output method="xml" version="1.0" encoding="ISO-8859-1"

B  B  <xsl:template match="sce/gd/act/body">

I think you want

B B  <xsl:template match="sce/gd/act/body">
B B B B B B B  <xsl:variable name="info"
select="document($ch)//gd/act/body/chap[sect[@id=current()/sect/@id]]"/>
B B B B B B B  <chap>
B B B B B B B B B B B  <xsl:attribute name="id">
B B B B B B B B B B B B B B B  <xsl:value-of select="$info/@id"/>
B B B B B B B B B B B  </xsl:attribute>
B B B B B B B B B B B  <xsl:copy>
B B B B B B B B B B B B B B B  <xsl:apply-templates select="@*|node()" />
B B B B B B B B B B B B B B B  <xsl:for-each select="$info/*">
B B B B B B B B B B B B B B B B B B B B B B B  <xsl:copy-of select="." />
B B B B B B B B B B B B B B B  </xsl:for-each>
B B B B B B B B B B B  </xsl:copy>
B B B B B B B  </chap>
B B B  </xsl:template>

There is no "sce" in the ID file so the path

B document($ch)//sce/gd/act/body/chap

seems wrong.
