This looks like one of those "spot the difference" competitions. In the 30
seconds I allow for looking at questions on this list, I can't spot the
difference between your lookup file and your output file.
Perhaps you should spend a little longer formulating the question.

Subject: [xsl] Lookup table and maintaining hierarchy
I had posted this question a long time, got some responses
but could not
solve the problem completely.
Consider my XML file that looks like this
<?xml version="1.0" encoding="utf-8" ?>
<TM>
<T id="something" TC="a">
<Type>b</Type>
<Prefs>
<UC>S</UC>
<UPS>1</UPS>
</Prefs>
<ST>
<T id="somethinga" TC="a">
<Type>b</Type>
<Prefs>
<UC>S</UC>
<UPS>1</UPS>
</Prefs>
<ST>
<T id="somethingb" TC="a">
<Type>b</Type>
<Prefs>
<UC>S</UC>
<UPS>1</UPS>
</Prefs>
</T>
<T id="somethingc" TC="a">
<Type>b</Type>
<Prefs>
<UC>S</UC>
<UPS>2</UPS>
</Prefs>
</T>
</ST>
</T>
<T id="somethingd" TC="a">
<Type>b</Type>
<Prefs>
<UC>S</UC>
<UPS>2</UPS>
</Prefs>
</T>
</ST>
</T>
<T id="somethinge" TC="a">
<Type>b</Type>
<Prefs>
<UC>S</UC>
<UPS>2</UPS>
</Prefs>
</T>
</TM>
With the following lookup file
<AB>
<TC name="a">
<TTM type="b">
<UCM preference="1">
<UC>S</UC>
<UPS>
<pa prefnum="1">
<XXXX>
<YYYY />
<ZZZZ />
</XXXX>
</pa>
<pa prefnum="2">
<WWWW />
</pa>
</UPS>
</UCM>
</TTM>
</TC>
</AB>
The generated output should look something like this
<AB>
<TC name="a">
<TTM type="b">
<UCM preference="1">
<UC>S</UC>
<UPS>
<pa prefnum="1">
<XXXX>
<YYYY />
<ZZZZ />
</XXXX>
</pa>
<pa prefnum="2">
<WWWW />
</pa>
</UPS>
</UCM>
</TTM>
</TC>
</AB>
I am using this stylesheet below
<?xml version="1.0" encoding="iso-8859-1"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version="1.0">
<xsl:output indent="yes"/>
<xsl:template match="T">
<xsl:variable name="tc" select="@TC"/>
<xsl:variable name="ttm" select="Type"/>
<xsl:variable name="uc" select="Prefs/UC"/>
<xsl:variable name="ups" select="Prefs/UPS"/>
<xsl:for-each select="document('ali-lookup.xml')">
<xsl:apply-templates mode="modify"
select="/AB/TC[(_at_)name=$tc]/TTM[(_at_)type=$ttm]/
UCM[UC=$uc]/UPS/pa[(_at_)prefnum=$ups]/*"/>
</xsl:for-each>
</xsl:template>
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="*" mode="modify" priority="2">
<p c="{name(.)}">
<xsl:apply-templates mode="modify"/>
</p>
</xsl:template>
<xsl:template match="@*|node()" mode="modify">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
I am getting this
<?xml version="1.0" encoding="utf-8" ?>
<S>
<p id="something1" c="XXXX">
<p id="something11" c="YYYY" />
<p id="something12" c="ZZZZ" />
</p>
<p id="somethinga1" c="XXXX">
<p id="somethinga11" c="YYYY" />
<p id="somethinga12" c="ZZZZ" />
</p>
<p id="somethingb1" c="XXXX">
<p id="somethingb11" c="YYYY" />
<p id="somethingb12" c="ZZZZ" />
</p>
<p id="somethingc1" c="WWWW" />
<p id="somethingd1" c="WWWW" />
<p id="somethinge1" c="WWWW" />
</S>
where every transformed node is at the same level. I want to preserve
the hierarchy of the original xml file. Any help is appreciated.
Thanks,
-Farooq.
