There's no "up front" in XSLT: no after, no before, no concept of time at
all. It's a stateless language. Concepually, everything happens at once.
Accordingly, there's no concept of writing to a variable "at the start" and
reading it "later".
Your two <xsl:variable name="buyerfullname"/> instructions are declaring
completely unrelated variables, the only thing they have in common is that
they both have the same name.
Just do the initialisation within the declaration of the global variable:
<xsl:variable name="buyer"
select="Contract/Borrowers/Borrower[NumOrder='1']"/>
<xsl:variable name="buyerfullname"
select="fn:borrowerfullname($buyer)"/>
You could make that
<xsl:variable name="buyerfullname"
select="if ($buyer) then fn:borrowerfullname($buyer) else ()"/>
but I would personally put the logic for that inside the function.

Subject: [xsl] Forgive the noob
Hi guys, doing my first XSLT and need a bit of help.
Basically, I'm transforming essentially a serialized object
structure into a list of field-value pair nodes.
There are a lot of complicated nodes I need to get at often,
like the first address node under the first customer so I
wanted to set up a bunch of variables and locate and and
assign helper variables before I get into the template
proper, which is itself very simple. I've written some
functions to help w/ this and a single named template called "init"
I call up front to set up the variables.
The problem is when I assign to the variables inside my named
template, they don't keep their value. I'd just add this
stuff to the main template but I really need to split all
this init stuff into an include file or something so they can
be reused in other xslts.
How can I make these variables visible where I need to use
them? Here's a bit of what I'm doing now:
<!-- declare global helper variables -->
<xsl:variable name="buyerfullname" select="''"/>
<xsl:variable name="buyeraddress" select="''"/>
<xsl:variable name="buyeraddress1" select="''"/>
<xsl:variable name="buyercsz" select="''"/>
<xsl:variable name="buyerhomephone" select="''"/>
<xsl:variable name="buyerblock" select="''"/>
<xsl:template name="init">
<xsl:variable name="buyer"
select="Contract/Borrowers/Borrower[NumOrder='1']"/>
<xsl:choose>
<xsl:when test="string($buyer) != ''">
<xsl:variable name="buyerfullname"
select="fn:borrowerfullname($buyer)"/>
<xsl:variable name="buyeraddress"
select="$buyer/Addresses/BorrowerAddress[IsCurrent='true' and
position()=1]"/>
<xsl:variable name="buyeraddress1"
select="fn:address1($buyeraddress)"/>
<xsl:variable name="buyercsz"
select="fn:csz($buyeraddress)"/>
<xsl:variable name="buyerhomephone"
select="$buyer/HomePhone/PhoneNumber"/>
<xsl:variable name="buyerblock"
select="string-join(($buyerfullname,$buyeraddress1,$buyercsz,$
buyerhomep
hone),fn:crlf())"/>
</xsl:when>
</xsl:choose>
</xsl:template>
<!-- create helper variables -->
<xsl:call-template name="init"/>
<!-- Main Template, generates FieldValuePairs -->
<!-- ERRORS: I GET 'VARIABLE DOES NOT EXIST' ERRORS -->
<xsl:template match="/">
<FieldValuePairs>
<FieldValuePair field="BuyerState">
ERROR ---> <xsl:attribute
name="value"><xsl:value-of
select="$buyeraddress/State"/></xsl:attribute>
</FieldValuePair>
<FieldValuePair
field="BuyerFullNameStreetCityStateZipPhone">
ERROR ---> <xsl:attribute
name="value"><xsl:value-of select="$buyerblock"/></xsl:attribute>
</FieldValuePair>
</FieldValuePairs>
</xsl:template>
Thanks for any help!
