Question

这是我的要求。我的示例输入文档如下所示。（我添加了白线以表明清楚）

<body>
       <p name="h-title" other="main">Introduction</p>
       <p name="h-titledesc " other="other-desc">XSLT and XQuery</p>


       <p name=""> XSLT is used to write stylesheets.</p>
    <p name="section-title" other=" other-section">XSLT</p>
    <p name="section-desc" other=" other-sectionsdesc">XSLT</p>
    <p name=""> Some text.</p>
    <p name="">
          <p1 name="bold"> XQuery is used to query XML databases.</p1>
       </p>
    <p name="h1-title" other=" other-h1">XSLT</p>
    <p name=""> Some text.</p>
       <p name="h2-title " name="other-h2">XQuery</p>
       <p name="">
          <p1 name="bold"> XQuery is used to query XML databases.</p1>
       </p>
       <p name="h3-title" name="other-h3">XQuery and stylesheets</p>
       <p name="">
          <p1 name="bold"> XQuery is used to query XML databases.</p1>
       </p>


    <p name="section-title" other=" other-section">XSLT</p>
    <p name="section-desc" other=" other-sectionsdesc">XSLT</p>
    <p name=""> Some text.</p>
    <p name="">
          <p1 name="bold"> XQuery is used to query XML databases.</p1>
       </p>
    <p name="h1-title" other=" other-h1">XSLT</p>
    <p name=""> Some text.</p>
       <p name="h2-title " name="other-h2">XQuery</p>
       <p name="">
          <p1 name="bold"> XQuery is used to query XML databases.</p1>
       </p>
       <p name="h3-title" name="other-h3">XQuery and stylesheets</p>
       <p name="">
          <p1 name="bold"> XQuery is used to query XML databases.</p1>
       </p>


       <p name ="summary-title">this is summary</p>
       <p name="summary-desc " other="other-summarydesc">the summary</p>
    </body>

现在我想要的输出就是这个。

<body>
       <p name="h-title" other="main">Introduction</p>
       <p name="h-titledesc " other="other-desc">XSLT and XQuery</p>

请帮我解决这个问题。

{的可选的 有一些限制：

h1，h2，h3依次来（这意味着，h3不介于h1和h2之间）
名称=＆＃34的行; section-title＆＃34;应该在name =＆＃34; section-desc＆＃34;
h1，h2，h3等应该在section-desc之后。

我解决了h1，h2，h3等here的问题。我知道这很有用。任何帮助都很棒。

如果违反这些规则，则不应发生转变。 }

Answer 1

这是我对先前发布的样式表的调整，它在调用递归函数分组级别之前只执行了额外的group-starting-with。我意识到这与你之前发表的帖子中的建议相同，但到目前为止，我不清楚为什么这个建议不适合你。

所以这是样式表：

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  xmlns:xs="http://www.w3.org/2001/XMLSchema"
  xmlns:mf="http://example.com/mf"
  exclude-result-prefixes="xs mf">

<xsl:param name="prefix" as="xs:string" select="'h'"/>
<xsl:param name="suffix" as="xs:string" select="'-title'"/>

<xsl:output method="xml" version="1.0" indent="yes"/>

<xsl:function name="mf:group" as="node()*">
  <xsl:param name="items" as="node()*"/>
  <xsl:param name="level" as="xs:integer"/>
  <xsl:for-each-group select="$items" group-starting-with="p[@name = concat($prefix, $level, $suffix)]">
    <xsl:choose>
      <xsl:when test="not(self::p[@name = concat($prefix, $level, $suffix)])">
        <xsl:apply-templates select="current-group()"/>
      </xsl:when>
      <xsl:otherwise>
        <xsl:element name="h{$level}">
          <xsl:apply-templates select="."/>
          <xsl:sequence select="mf:group(current-group() except ., $level + 1)"/>
        </xsl:element>
      </xsl:otherwise>
    </xsl:choose>
  </xsl:for-each-group>
</xsl:function>

<xsl:template match="@* | node()">
  <xsl:copy>
    <xsl:apply-templates select="@* , node()"/>
  </xsl:copy>
</xsl:template>

<xsl:template match="body">
  <xsl:copy>
    <xsl:for-each-group select="*" group-starting-with="p[@name = 'section-title' or @name = 'summary-title']">
      <xsl:choose>
        <xsl:when test="not(self::p[@name = 'section-title' or @name = 'summary-title'])">
          <xsl:apply-templates select="current-group()"/>
        </xsl:when>
        <xsl:otherwise>
          <body-contents>
             <xsl:sequence select="mf:group(current-group(), 1)"/>
          </body-contents>
        </xsl:otherwise>
      </xsl:choose>
    </xsl:for-each-group>
  </xsl:copy>
</xsl:template>

</xsl:stylesheet>

当我将带有Saxon 9.4的样式表应用于更正的输入

时

<body>
       <p name="h-title" other="main">Introduction</p>
       <p name="h-titledesc " other="other-desc">XSLT and XQuery</p>


       <p name=""> XSLT is used to write stylesheets.</p>
    <p name="section-title" other=" other-section">XSLT</p>
    <p name="section-desc" other=" other-sectionsdesc">XSLT</p>
    <p name=""> Some text.</p>
    <p name="">
          <p1 name="bold"> XQuery is used to query XML databases.</p1>
       </p>
    <p name="h1-title" other=" other-h1">XSLT</p>
    <p name=""> Some text.</p>
       <p name="h2-title" other="other-h2">XQuery</p>
       <p name="">
          <p1 name="bold"> XQuery is used to query XML databases.</p1>
       </p>
       <p name="h3-title" other="other-h3">XQuery and stylesheets</p>
       <p name="">
          <p1 name="bold"> XQuery is used to query XML databases.</p1>
       </p>


    <p name="section-title" other=" other-section">XSLT</p>
    <p name="section-desc" other=" other-sectionsdesc">XSLT</p>
    <p name=""> Some text.</p>
    <p name="">
          <p1 name="bold"> XQuery is used to query XML databases.</p1>
       </p>
    <p name="h1-title" other=" other-h1">XSLT</p>
    <p name=""> Some text.</p>
       <p name="h2-title" other="other-h2">XQuery</p>
       <p name="">
          <p1 name="bold"> XQuery is used to query XML databases.</p1>
       </p>
       <p name="h3-title" other="other-h3">XQuery and stylesheets</p>
       <p name="">
          <p1 name="bold"> XQuery is used to query XML databases.</p1>
       </p>


       <p name ="summary-title">this is summary</p>
       <p name="summary-desc " other="other-summarydesc">the summary</p>
    </body>

我得到了输出

<body>

   <p name=""> XSLT is used to write stylesheets.</p>

</body>

请在下次提供输入样本时确保其格式正确，到目前为止，您始终发布<p name="h2-title " name="other-h2">XQuery</p>之类的内容，并且无法使用同名的两个属性。

使用xsl：for-each-group
