XSL测试空字符串<xsl:if>和分类

  •  14
  • AdRock  · 技术社区  · 16 年前

    我正在使用 <xsl:if test="string-length(node) != 0"> 然后对每个节点进行输出,但不打印任何内容。就像测试返回零。

    我已经选择了要检查长度的每个节点的父节点作为模板匹配,但仍然不起作用。

    另一件事,如何使用 <datefrom> . 我试着使用这个,但是在加载样式表时出现了一个错误。如果我把它拿出来

    <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">

    应用模板时,可以对元素进行排序:

    <xsl:apply-templates select="folktask/member">
      <xsl:sort select="festival/event/datefrom"/>
    </xsl:apply-templates>
    

    <xsl:template match="conaddress2">
      <xsl:if test="string-length(conaddress2)!=0">
        ...
      </xsl:if>
    </xsl:template>
    

    应该是:

    <xsl:template match="conaddress2">
      <xsl:if test="string-length(.)!=0">
        ...
      </xsl:if>
    </xsl:template>
    

    既然你匹配了 conaddress2 string-length(conaddress2) 通信地址2 当前上下文节点的子节点(即 通信地址2 ). 换言之,你想找出 conaddress2\conaddress2

    与此模板类似:

    <xsl:template match="contact">
      <xsl:if test="string-length(contelephone)!=0">
        <div class="small bold">TELEPHONE:</div>
        <div class="large">
          <xsl:value-of select="contelephone/." />
        </div>
      </xsl:if>
    
      <xsl:if test="string-length(conmobile)!=0">
        <div class="small bold">MOBILE:</div>
        <div class="large">
          <xsl:value-of select="conmobile/." />
        </div>
      </xsl:if>
    
      <xsl:if test="string-length(fax)!=0">
        <div class="small bold">FAX:</div>
        <div class="large">
          <xsl:value-of select="fax/." />
        </div>
      </xsl:if>
    </xsl:template>
    

    您可以删除 "/." 从您的选择表达式。所以不是:

    <xsl:value-of select="contelephone/." />
    

    你可以用

    <xsl:value-of select="contelephone" />
