If you want the children of question/info to be copied, then you need to
copy them, just as you are currently copying the attributes. For example you
could do:
<xsl:template match="question/info">
<xsl:copy>
<xsl:copy-of select="@*|*"/> <!-- note change here -->
<xsl:variable name="question_g_code" select="notes"/>
<xsl:for-each select="$standardFile">
<xsl:copy-of select="key('standard_by_g_code',
$question_g_code)"/>
</xsl:for-each>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>

Subject: [xsl] using key to merge data
Greetings,
I am trying to merge a set of standards into another xml
file. I have tried using document() pointing to a separate
file as well as incorporating the standards into the
stylesheet. With both methods I run into a similar problem.
The standards information merges fine.
However, it removes the sibling nodes from tree. Here is the
basic structure of the xml file I am importing into:
<top>
<question>
<info>
<topic>Vocabulary</topic>
<keyword>Prefixes</keyword>
<notes>G4U1S01></notes>
<foo>blah blah</foo>
</info>
</question>
</top>
The standards.xml file looks like this:
<top>
<standard>
<g_code>G4U1S01</g_code>
<state-obj state="AZ">blah blah blah</state-obj>
<state-obj state="TX">blah blah blah</state-obj>
. . .
</standard>
</top>
When I run the stylesheet below, the <notes> node along with
all the sibling nodes are removed from the <info> node.
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:import href="copy.xslt"/>
<xsl:output method="xml"/>
<xsl:variable name="standardFile"
select="document('standards.xml')"/>
<xsl:key name="standard_by_g_code" match="standard" use="g_code"/>
<xsl:template match="/">
<xsl:copy>
<xsl:apply-templates/>
</xsl:copy>
</xsl:template>
<xsl:template match="question/info">
<xsl:copy>
<xsl:copy-of select="@*"/>
<xsl:variable name="question_g_code" select="notes"/>
<xsl:for-each select="$standardFile">
<xsl:copy-of select="key('standard_by_g_code',
$question_g_code)"/>
</xsl:for-each>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
The current result looks like this:
<top>
<question>
<info>
<standard>
<g_code>G4U1S01</g_code>
<state-obj state="AZ">blah blah blah</state-obj>
<state-obj state="TX">blah blah blah</state-obj>
. . .
</standard>
</info>
</question>
</top>
I am looking for this:
<top>
<question>
<info>
<topic>Vocabulary</topic>
<keyword>Prefixes</keyword>
<notes>G4U1S01></notes>
<foo>blah blah</foo>
<state-obj state="AZ">blah blah blah</state-obj>
<state-obj state="TX">blah blah blah</state-obj>
. . .
</info>
</question>
</top>
No doubt there something simple that I am doing wrong.
FYI: the <xsl:import href="copy.xslt"/> points to this stylesheet:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:template match="node( ) | @*">
<xsl:copy>
<xsl:apply-templates select="@* | node( )"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
Thanks in advance.
Terry
