使用XSLT将第一个HTML表行转换为每个表的标题行

Question

使用XSLT将第一个HTML表行转换为每个表的标题行

我的XML里面有一些html内容.以前我可以<xsl:copy-of select="customFields/customField[@name='mainContent']/html"/>用来将内容拉到正确的区域.一个新的要求是将<tr>每个表中的第一个转换<tbody>为一组thead/tr/th.

我对如何转换感到困惑,事实上甚至没有在哪里开始:

...

<customField name="mainContent" type="Html">
    <html>
        <h1>Page Heading</h1>
        <p>Gusto te minim tempor elit quam. Dolore vel accumsan parum option me. Demonstraverunt congue nisl soluta tincidunt seacula. Soluta saepius demonstraverunt praesent claritatem mutationem. Modo te ullamcorper vel augue veniam. Nunc investigationes dolor iriure typi in.</p>

        <table cellspacing="0" cellpadding="0" summary="" border="0">
            <tbody>
                <tr>
                    <td>Heading 1</td>
                    <td>Heading 2</td>
                    <td>Heading 3</td>
                </tr>
                <tr>
                    <td>sample</td>
                    <td>sample</td>
                    <td>sample</td>
                </tr>
                <tr>
                    <td>sample</td>

                    <td>sample</td>

我的 XML 中有一些 html 内容。以前我只能使用 <xsl:copy-of select="customFields/customField[@name='mainContent']/html"/> 将内容拉入正确的区域。一个新的要求是将<tr>每个表中的第一个转换<tbody>为一组thead/tr/th.

这种转变：

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>
 <xsl:strip-space elements="*"/>

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

 <xsl:template match="tbody/tr[1]">
  <thead>
    <tr>
      <xsl:apply-templates/>
    </tr>
  </thead>
 </xsl:template>

 <xsl:template match="tbody/tr[1]/td">
  <th><xsl:apply-templates/></th>
 </xsl:template>
</xsl:stylesheet>

请注意：

使用“覆盖身份规则”设计模式。这是最基本、最强大的 XSLT 设计模式。

更新：

正如 Flynn1179 所注意到的，OP 对问题的定义（上面）与他提供的所需结果不一致。在此输出中，不仅的第一个tr内部tbody被转换为thead/tr（及其td子级th），而且thead被移动到的外部tbody。

如果这确实是OP想要的，这里也是针对这种情况的修改解决方案：

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>
 <xsl:strip-space elements="*"/>

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

 <xsl:template match="tbody/tr[1]">
  <thead>
   <tr>
    <xsl:apply-templates/>
   </tr>
  </thead>
  <tbody>
   <xsl:apply-templates 
        select="following-sibling::tr"/>
  </tbody>
 </xsl:template>

 <xsl:template match="tbody/tr[1]/td">
  <th>
   <xsl:apply-templates/>
  </th>
 </xsl:template>

 <xsl:template match="tbody">
  <xsl:apply-templates select="tr[1]"/>
 </xsl:template>
</xsl:stylesheet>
