XSL怎样获取属性名称为变量的属性
<script language="javascript" type="text/javascript">
 <xsl:variable name="proCount" select="count(@*[starts-with(name(),'a')])"/>
 proCount = "<xsl:value-of select="$proCount"/>";
 <![CDATA[
 for(i = 1; i <= proCount; i++)
 {
  priName = "a"+i;
 ]]>
  sss = "<xsl:value-of select="priName" />";
  alert(sss);
 <![CDATA[
 }
 ]]>
</script>

priName为变量！这样写不行！要怎么写啊！

[解决办法]

XML code

arr = [ <xsl:for-each select="//note/@*[starts-with(name(),'a')]">'<xsl:value-of select="."/>'<xsl:if test="position()!=count(//note/@*[starts-with(name(),'a')])">,</xsl:if></xsl:for-each> ];
