<?xml version='1.0' encoding='utf-8' ?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" >
<xsl:output method="html"/>
<xsl:template match="/">
无言无言无言
<form action="test.aspx" method="post">
<p>
<xsl:apply-templates select="test"/>
</p>
<p>
<input type="submit" value="Submit"/>
<input type="reset" value="Reset"/>
</p>
</form>
</xsl:template>
<xsl:template match="test">
<xsl:for-each select="testid">
<p>题目: </p>
<xsl:value-of select="say"/>
<xsl:for-each select="answers">
<xsl:for-each select="answer">
<p>
<input type="radio" CHECKED="0" value="text()" name="ancestor::testid/@id" >
<xsl:value-of select=" text()"/>
</input>
</p>
</xsl:for-each> </xsl:for-each>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>

使用此语法:

name="{ancestor::testid/@id}"
