Xslt XLS在条件满足时创建新元素

我收到这个错误：

元素类型“xsl:if”必须由 匹配的结束标记“”

当我试图关闭和打开一个新的

fo:block

时，如果满足某个条件

<xsl:if test=".[@pdf_break='true']">
        </fo:block><fo:block>
</xsl:if>

当属性为

true

时

XML示例：

<contrib-group>
    <contrib equal-contrib="yes" contrib-type='author' pdf_break='false'>
        <name>
            <surnameExample1</surname>
            <given-names>Example1</given-names>
        </name>
        <xref ref-type='aff' rid='ID1'><sup>1</sup></xref>
    </contrib>
    <contrib equal-contrib="yes" contrib-type='author' pdf_break='false'>
        <name>
            <surname>Example2</surname>
            <given-names>Example2</given-names>
        </name>
        <xref ref-type='aff' rid='ID2'><sup>2</sup></xref>
        <xref ref-type='aff' rid='ID3'><sup>3</sup></xref>
        <xref ref-type='aff' rid='ID4'><sup>4</sup></xref>
        <xref ref-type='aff' rid='ID5'><sup>5</sup></xref>
    </contrib>
    <contrib equal-contrib="yes" contrib-type='author' pdf_break='true'>
        <name>
            <surname>Example3</surname>
            <given-names>Example3</given-names>
        </name>
        <xref ref-type='aff' rid='ID2'><sup>2</sup></xref>
    </contrib>
    <contrib contrib-type='author' pdf_break='false'>
        <name>
            <surname>Example4</surname>
            <given-names>Example4</given-names>
        </name>
        <xref ref-type='aff' rid='ID6'><sup>6</sup></xref>
    </contrib>
    <contrib contrib-type='author' pdf_break='false'>
        <name>
            <surname>Example5</surname>
            <given-names>Example15</given-names>
        </name>
        <xref ref-type='aff' rid='ID2'><sup>2</sup></xref>
    </contrib>
</contrib-group>

我认为，如果您有权访问XSLT2或3，您可以使用

  <xsl:template match="contrib-group">
      <xsl:for-each-group select="contrib[@contrib-type = 'author']" group-starting-with="*[@pdf_break = 'true']">
          <fo:block>
              <xsl:apply-templates select="current-group()"/>
          </fo:block>
      </xsl:for-each-group>
  </xsl:template>



是一个最小的示例，当然您需要为XSL-FO转换中的剩余XML输入添加模板。
使用：

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
 xmlns:fo="http://www.w3.org/1999/XSL/Format">

  <xsl:template match="/*">

      <fo:block>
         <xsl:for-each select="current-group()">
           <author><xsl:sequence select="name/surname, name/given-names"/></author>
         </xsl:for-each>

当应用于同一XML文档（如上）时，再次生成正确的结构化输出：

是向后的：它必须是

。这是不可能的。XSLT样式表还必须是格式良好的XML文档。一般实体格式良好的结果是XML文档中的逻辑和物理结构被正确嵌套；任何开始标记、结束标记、空元素标记、元素、注释、处理指令、字符引用或实体引用都不能在一个实体中开始，在另一个实体中结束请显示输入的示例-请参阅：。我在示例中添加了
contrib组
级别的输入，如果需要更多的父级，请告诉我。谢谢。我想您应该为每个组使用
，
组相邻=“@pdf\u break”
或
组以=“*[@pdf\u break='true']”开头。请参阅中的示例或关于分组或编辑您的问题的任何其他介绍，并在问题末尾向我们展示您希望输入样本的结果。Martin，按照我对问题的理解，似乎必须使用以
结尾的
组，而不是以
@user3783243:开头的
组，这取决于条件。你可以通过Gmail的dnovatchev与我联系
