 I'm trying again to seek your help. This problem has been irking me for a couple of days now and I'm at my wit's end trying to solve it. I have significantly simplified my input and lookup files, so I'll appreciate it greatly if somebody can take a look and help me. I have the following input file, where the pref element indicates a lookup field from a different file. <?xml version="1.0" encoding="utf-8" ?>
<TM>
<T id="id1">
<pref>1</pref>
<T id="id2">
<pref>1</pref>
<T id="id3">
<pref>3</pref>
</T>
</T>
</T>
</TM>The lookup file is as follows. <?xml version="1.0" ?>
<AB>
<pa prefnum="1">
<XXXX>
<YYYY />
<ZZZZ />
</XXXX>
</pa>
<pa prefnum="2">
<WWWW />
</pa>
<pa prefnum="3">
<AAAA>
<BBBB />
<CCCC />
<DDDD>
<EEEE />
<FFFF />
</DDDD>
</AAAA>
</pa>
</AB>Each T element in the original file has to be replaced by a set of p elements whose attributes are set based on the lookup performed and the id from the original file. So the first T element with id = id1 and pref = 1 should be replaced by the following <p c="XXXX" id="id11">
<p c="YYYY" id="id112" />
<p c="ZZZZ" id="id114" />
</p>I am able to do the lookup successfully, but am unable to maintain the hierarchy of the source tree. This is my stylesheet <?xml version="1.0" encoding="UTF-8" ?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output indent="yes" /> <xsl:template match="/">
<Root>
<xsl:apply-templates />
</Root>
</xsl:template><xsl:template match="//T"> <xsl:apply-templates select="document('lookup.xml')//AB/pa[@prefnum=current()/pref]/*" mode="p"> <xsl:with-param name="id" select="@id" /> </xsl:apply-templates> <xsl:apply-templates select="*" /> </xsl:template> <xsl:template match="pref"></xsl:template> <xsl:template mode="p" match="*"> <xsl:param name="id">IDENTIFIER</xsl:param> <xsl:variable name="idd" select="translate($id,' ','_')"></xsl:variable> <xsl:variable name="newid" select="concat($idd, position())"></xsl:variable> <p c="{name()}" id="{$newid}"> <xsl:apply-templates mode="p"> <xsl:with-param name="id" select="$newid" /> </xsl:apply-templates> </p> <xsl:apply-templates /> </xsl:template> </xsl:stylesheet> Based on this, I'm getting the following output. <?xml version="1.0" encoding="UTF-8" ?>
<Root>
<p c="XXXX" id="id11">
<p c="YYYY" id="id112" />
<p c="ZZZZ" id="id114" />
</p>
<p c="XXXX" id="id21">
<p c="YYYY" id="id212" />
<p c="ZZZZ" id="id214" />
</p>
<p c="AAAA" id="id31">
<p c="BBBB" id="id312" />
<p c="CCCC" id="id314" />
<p c="DDDD" id="id316">
<p c="EEEE" id="id3162" />
<p c="FFFF" id="id3164" />
</p>
</p>
</Root>The correct output that I desire is <?xml version="1.0" encoding="UTF-8" ?>
<Root>
<p c="XXXX" id="id11">
<p c="YYYY" id="id112" />
<p c="ZZZZ" id="id114" /> <p c="XXXX" id="id21">
<p c="YYYY" id="id212" />
<p c="ZZZZ" id="id214" /> <p c="AAAA" id="id31">
<p c="BBBB" id="id312" />
<p c="CCCC" id="id314" />
<p c="DDDD" id="id316">
<p c="EEEE" id="id3162" />
<p c="FFFF" id="id3164" />
</p>
</p>
</p>
</p>
</Root>If I move the <xsl:apply-templates select="*" /> command from the T template and move it within the mode=p template, then it works for only the first T element. I'm assuming this is because the context has switched to the lookup file and at that point, it's unable to find any more T elements there. So how do I restore the context back to the original file *at that point*? Please help!
