How do I transmit the value of the id attribute in the XML file down
to the newly created elements?
In your <xsl:apply-templates> you can use <xsl:with-param> to pass the
id attribute value, and then in your <xsl:template> you use <xsl:param>
to declare the expectation of receiving that value. You'll have to do
this for all <xsl:apply-templates> instructions that will be triggered
once engaged, which means you will have to override the built-in
template rule for an element if that is one of the ones being used.
In the fragment below, the id is "something", so the XML that is
generated should look something like this
<p id="something1" c="XXXX">
<p id="something11" c="YYYY"/>
<p id="something12" c="ZZZZ"/>
</p>
for the first case
and
<p id="something1" c="WWWW"/>
for the second case.
Once you have the id value, you can use numbering techniques for the
suffix.
A broader question that I have is how to relate (or tie) the nodes in
the main XML file when the context has switched to the lookup file.
By passing your desired value at *every* change in context, as I've
described above.
I hope this helps.

That was certainly helpful. Using a combination of concat and position(),
I was also able to get the numbering done. However, another issue needs
to be resolved.
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
<?xml version="1.0" encoding="utf-8" ?>
<S>
<p id="something1" c="XXXX">
<p id="something11" c="YYYY" />
<p id="something12" c="ZZZZ" />
<p id="somethinga1" c="XXXX">
<p id="somethinga11" c="YYYY" />
<p id="somethinga12" c="ZZZZ" />
<p id="somethingb1" c="XXXX">
<p id="somethingb11" c="YYYY" />
<p id="somethingb12" c="ZZZZ" />
</p>
<p id="somethingc1" c="WWWW" />
</p>
<p id="somethingd1" c="WWWW" />
</p>
<p id="somethinge1" c="WWWW" />
</S>
What I am getting with a modified version of this spreadsheet that
Ken had kindly provided
<?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>
is 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 xml file. Any help is appreciated.
Thanks,
-Farooq.
