<?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="/"><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>

语法:

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