-- 一个XSL的问题, 谢谢各位了
这是XML: <?xml version="1.0" encoding="ISO-8859-1"?>
<records name="offerlist">
<record>
<country>HK</country>
<name>hk offer1</name>
</record>
<record>
<country>HK</country>
<name>hk offer2</name>
</record>
<record>
<country>HK</country>
<name>hk offer3</name>
</record>
<record>
<country>HK</country>
<name>hk offer4</name>
</record>
<record>
<country>SG</country>
<name>sg offer1</name>
</record>
<record>
<country>SG</country>
<name>sg offer2</name>
</record>
<record>
<country>SG</country>
<name>sg offer3</name>
</record>
<record>
<country>TW</country>
<name>tw offer1</name>
</record>
<record>
<country>TW</country>
<name>tw offer2</name>
</record>
<record>
<country>TW</country>
<name>tw offer3</name>
</record>
</records>
<records name="countrylist">
<record>
<country>HK</country>
<name>Hong Kong</name>
</record>
<record>
<country>CN</country>
<name>China</name>
</record>
<record>
<country>SG</country>
<name>Singapor</name>
</record>
</records> 这是XSL: <?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="/">
<html>
<body>
<h2>Country Offer</h2>
<table border="1">
<xsl:for-each select="records[@name='offerlist']/record">
<xsl:call-template name="displayCountry" />
<xsl:call-template name="displayName" />
</xsl:for-each>
</table>
</body>
</html>
</xsl:template>
<xsl:template name="displayCountry">
<xsl:variable name="currentCountry">
<xsl:value-of select="country"/>
</xsl:variable>
<xsl:variable name="prevpos" select="position()-1"/>
<xsl:variable name="previousCountry">
<xsl:choose>
<xsl:when test="$prevpos > 0">
<xsl:value-of select="../record[$prevpos]/country"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="''"/>
</xsl:otherwise>
</xsl:choose>
</xsl:variable>
<xsl:if test="$currentCountry != $previousCountry">
<tr><td><b>Country: <xsl:value-of select="$currentCountry"/></b></td></tr>
</xsl:if>
</xsl:template> <xsl:template name="displayName">
<xsl:for-each select="name">
<tr><td><xsl:value-of select="."/></td></tr>
</xsl:for-each>
</xsl:template> </xsl:stylesheet> 我想在XSL原有的基础上做些改动, 使得"offerlist"里面的"country"可以跟"countrylist"里面的"country"做比较, 然后把"countrylist"里面的"country"显示出来
