我在.xsl文件中声明了一个变量.现在我想用新值更新旧值.例如:

<?xml version="1.0" encoding="iso-8859-1"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                              xmlns:w="http://schemas.openxmlformats.org/wordprocessingml/2006/main">

<xsl:output method="html" indent="yes"/>

  <xsl:template match="/">

    <Document>
      <xsl:variable name="topLevelHeadings" select = "//w:body/w:p[w:pPr[w:pStyle[@w:val='Heading1']]]"/>
      <xsl:variable name="beforeHeading" select="false()"/>


      <xsl:choose>

       <xsl:when test="$beforeHeading">
          <xsl:apply-templates select="//w:body/w:p">
            <xsl:with-param name="scope" select="count(//w:body/child::*)-1"/>
          </xsl:apply-templates>
       </xsl:when> 

        <xsl:when test="$topLevelHeadings">
          <xsl:variable name="beforeHeading" select="true()"/>
          <xsl:apply-templates select="$topLevelHeadings">
               <xsl:with-param name="scope" select="count(//w:body/child::*)-1"/>
          </xsl:apply-templates>
        </xsl:when>

        <xsl:otherwise>
          <xsl:apply-templates select="//w:body/w:p[w:r[w:t]]">
               <xsl:with-param name="scope" select="count(//w:body/child::*)-1"/>
          </xsl:apply-templates>
        </xsl:otherwise>
      </xsl:choose>
    </Document>
  </xsl:template>

  <xsl:template match="w:body/w:p">
    <xsl:param name = "scope"/>
    <xsl:variable name ="index" select="count(preceding-sibling::*)"/>
    <xsl:if test = "$index &lt;= $scope">
      <Paragraph>
        <xsl:attribute name="index">
          <xsl:value-of select="$index" />
        </xsl:attribute>
        <xsl:apply-templates select=".//w:r/w:t"/> …
