String comparison in XSLT
When I call this template I get the following results.
155IT Matches 155OO
155OO Matches 155OO
155PP
The XML I am processing does have three rows and those are the values, but why is the test returning true for the first two and false for the last one? How should I be doing the string comparison?
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:template name="ProofOfConcept">
<xsl:param name="Lines"/>
<xsl:param name="MainDeliveryCode"/>
<xsl:choose>
<xsl:when test="$Lines">
<xsl:variable name="CurrentDeliveryCode" select="$Lines/DLVYLOCCD"/>
<p>
<xsl:choose>
<xsl:when test=" $MainDeliveryCode = $CurrentDeliveryCode">
<xsl:value-of select="$CurrentDeliveryCode"/> Matches <xsl:value-of select="$MainDeliveryCode"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$Lines"/> Fails <xsl:value-of select="$MainDeliveryCode"/>
</xsl:otherwise>
</xsl:choose>
</p>
<xsl:call-template name="ProofOfConcept">
<xsl:with-param name="Lines" select="$Lines[position() > 1]"/>
<xsl:with-param name="MainDeliveryCode" select="$MainDeliveryCode"/>
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
<xsl:template match="/">
<html>
<head>
<title></title>
</head>
<body>
<xsl:call-template name="ProofOfConcept">
<xsl:with-param name="Lines" select="data/Lines/LINE"/>
开发者_运维百科 <xsl:with-param name="MainDeliveryCode" select="data/header/DLVYLOCCD"/>
</xsl:call-template>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
Sample data
<?xml version="1.0"
encoding="ISO-8859-1"
standalone="yes"?> <data>
<header><DLVYLOCCD>155OO</DLVYLOCCD>
</header> <Lines>
<LINE><DLVYLOCCD>155IT</DLVYLOCCD></LINE>
<LINE><DLVYLOCCD>155OO</DLVYLOCCD></LINE>
<LINE><DLVYLOCCD>155PP</DLVYLOCCD></LINE>
</Lines> </data>
Thanks for any advice.
Here is a less painful version of your XSLT:
<xsl:stylesheet
version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
>
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:template match="data">
<html>
<head>
<title></title>
</head>
<body>
<!-- this selects the matching LINE node(s), or nothing at all -->
<xsl:apply-templates select="
Lines/LINE[DLVYLOCCD = /data/header/DLVYLOCCD]
" />
</body>
</html>
</xsl:template>
<xsl:template match="LINE">
<p>
<!-- for the sake of the example, just output a copy -->
<xsl:copy-of select="." />
</p>
</xsl:template>
</xsl:stylesheet>
gives (formatted result):
<?xml version="1.0" encoding="utf-8"?>
<html>
<head>
<title></title>
</head>
<body>
<p>
<LINE><DLVYLOCCD>155OO</DLVYLOCCD></LINE>
</p>
</body>
</html>
There are a few things wrong with your implementation. Most important, the expression:
<xsl:variable name="CurrentDeliveryCode" select="$Lines/DLVYLOCCD"/>
returns a node-set consisting of all the DLVYLOCCD elements, not just the current one as you seem to assume. Also, you shouldn't be using recursion to iterate. Use <xsl:for-each> instead, in which case you will process the items one at a time.
I figured it out.
I need to change my test to
<xsl:when test="contains($MainDeliveryCode, $CurrentDeliveryCode" >
That solved the problem.
