RE: [xsl] XSL variable out of scope

["Andy J. Cupp" <acupp@xxxxxxxxxxxxxxx>]

Hi Nischal.  Instead of relying so much on variables, maybe you should use XPath more.  For instance, given your xml structure, the XPath expression "/PhoneList/Phone[PhoneUseCode='BUS']/PhoneNumber" would return all PhoneNumber elements that   go with businesses.  So really you don't have to store these numbers ahead of time.  If you need some help with XPath, there's plenty of good online references and tutorials. 

Hope I was some help,
Andy

Subject: [xsl] XSL variable out of scope


Hi All,

I have an xml and xsl like the following. When I apply
the xsl I need to get the following HTML

Home: 4089888888
Business: 40888888

But I get an error saying variable out of scope. And I
know I am using a variable declared in a different
scope. I am kinda stuck here and I dont have any more
ideas to counter this. Can someone help me find a way
to tackle this problem. 

PhoneList.xml

<?xml-stylesheet type="text/xsl"
href="C:\TestXSLT\xsl\PhoneList.xsl"?>
<PhoneList>
	<Phone>
		<PhoneUseCode>BUS</PhoneUseCode>
		<PhoneNumber>4082389033</PhoneNumber>
	</Phone>
	<Phone>
		<PhoneUseCode>HOME</PhoneUseCode>
		<PhoneNumber>4082834798</PhoneNumber>
	</Phone>
</PhoneList>


PhoneList.xsl

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:fo="http://www.w3.org/1999/XSL/Format";>
<xsl:template match="/">
<xsl:for-each select="//PhoneList/Phone">
	<xsl:variable name="PhUseCode"
select="PhoneUseCode"/>
	<xsl:choose>
		<xsl:when test="$PhUseCode='HOME'">
<xsl:variable name="HomePhone" select="PhoneNumber"/>
	</xsl:when>
	<xsl:when test="$PhUseCode='BUS'">
<xsl:variable name="BusPhone" select="PhoneNumber"/>
	</xsl:when>
</xsl:choose>
</xsl:for-each>
<tr>
	<td>&#160;</td><td>&#160;</td>
	<td nowrap="nowrap"
colspan="2">&#160;&#160;&#160;Home</td>
				<td nowrap="nowrap">"<xsl:value-of
select="$HomePhone"/></td>
			</tr>
			<tr>
				<td>&#160;</td>
				<td>&#160;</td>
				<td nowrap="nowrap"
colspan="2">&#160;&#160;&#160;Business</td>
				<td nowrap="nowrap"><xsl:value-of
select="$BusPhone"/></td>
			</tr>
	</xsl:template>
</xsl:stylesheet>
