使用XSLT生成具有jQuery树表属性的表

Question

使用Saxon XSLT 2.0，如果绝对必要的话，可以使用XSLT 3.0。

主要问题是生成<tr>属性id和父id (data-tt-id和data-tt-parent-id)，它们是由短划线分隔的数字序列，库用于显示它们(它们必须按顺序)。有没有什么有效方法的建议？我正在考虑不断更新一个字符串变量，也就是说，如果XSLT以正确的顺序(深度优先，按顺序，不受任何多线程的影响)遍历。否则，我可能不得不聪明地计算每个值的祖先等，这似乎非常低效。我对XSLT有些陌生;)

<table id="example-basic">
  <caption>Basic jQuery treetable Example</caption>
  <thead>
    <tr>
      <th>Tree column</th>
      <th>Additional data</th>
    </tr>
  </thead>
  <tbody>
    <tr data-tt-id="1">
      <td>Node 1: Click on the icon in front of me to expand this branch.</td>
      <td>I live in the second column.</td>
    </tr>
    <tr data-tt-id="1.1" data-tt-parent-id="1">
      <td>Node 1.1: Look, I am a table row <em>and</em> I am part of a tree!</td>
      <td>Interesting.</td>
    </tr>
    <tr data-tt-id="1.1.1" data-tt-parent-id="1.1">
      <td>Node 1.1.1: I am part of the tree too!</td>
      <td>That's it!</td>
    </tr>
    <tr data-tt-id="2">
      <td>Node 2: I am another root node, but without children</td>
      <td>Hurray!</td>
    </tr>
  </tbody>
</table>

这些示例和jQuery树表在http://ludo.cubicphuse.nl/jquery-treetable/#usage上有更详细的描述

我正在生成一个jQuery树表，类似于他们的拖放复杂树：

<table id="example-advanced">
  <caption>
    <a href="#" onclick="jQuery('#example-advanced').treetable('expandAll'); return false;">Expand all</a>
    <a href="#" onclick="jQuery('#example-advanced').treetable('collapseAll'); return false;">Collapse all</a>
  </caption>
  <thead>
    <tr>
      <th>Name</th>
      <th>Kind</th>
      <th>Size</th>
    </tr>
  </thead>
<tbody>

我在将您的输入与输出关联起来时遇到了一些小问题，但我认为使用xsl:number level="multiple"就可以做到这一点。就像这样

<xsl:template match="folder">
  <td>
    <xsl:attribute name="data-tt-id">
      <xsl:number level="multiple" count="folder" format="1-1"/>
    </attribute>
    <xsl:attribute name="data-tt-parent-id">
      <xsl:number select=".." level="multiple" count="folder" format="1-1"/>
    </xsl:attribute>
     ...
    <xsl:apply-templates/>
  </td>
</xsl:template>
