xml - 片段输入 xhtml 以使用祖先节点分离 xhtml 文件

Question

有人可以帮我解决这个问题。非常感谢。

要求：

要为每个 pal:fragment 元素生成单独的 html 文件，对于附加的源文档，文件的名称基于 pal:fragment 元素上的@fragment-id。
'pal:fragment' 可以嵌套，用 'div' 元素包裹。
分片文件不仅应包含 pal:fragment 的所有子元素，还应包含其祖先 'div' 元素。从 'pal:fragment' 生成的每个单独文件不应包含其后代 'pal:fragment 内容的内容。

请参阅以下示例以了解需求

示例 1：如果为 'pal:fragment' fragment-id="DLM3989039" 生成片段文件，内容应如下所示（删除 html 标记以便于理解）

<div class="bill" id="DLM3988900">
    <div class="schedule-group">
        <div class="schedule" id="DLM3989039">
            <p>DLM3989039 dummy text </p>
            <div class="schedule-provisions"></div>
        </div>
    </div>
</div>

示例 2：如果为 'pal:fragment' fragment-id="DLM3989044" 生成片段文件，则内容应如下所示。（为了便于理解，去掉了 html 标记）

<div class="bill" id="DLM3988900">
    <div class="schedule-group">
        <div class="schedule" id="DLM3989039">
            <div class="schedule-provisions">
                <div class="part" id="DLM3989044">
                    <p>DLM3989044 dummy content</p>
                </div>
            </div>
        </div>
    </div>
</div>

=============

虽然使用上面附加/提到的示例文件，但生成的单独 html 文件的数量为“11”，这（文件数量）符合预期。我的 XSLT 样式表有问题。生成的输出如下所示（以下提及）：

'foo:fragment' 的祖先节点未正确嵌套，并且不包含片段内容作为其子/后代，而是作为兄弟节点写入。

获取由“DLM3989039”“pal:fragment”元素生成的 html 单独文件

<html xmlns="http://www.w3.org/1999/xhtml">
   <head>
      <meta http-equiv="Content-Type" content="text/html; charset=utf-8"></meta>
   </head>
   <body>
      <div class="schedule-group">
         <div class="bill" id="DLM3988900"></div>
      </div>
      <div xmlns:foo="http://www.google.nz/rendition-info" class="schedule" id="DLM3989039">

-a---        24.10.2012     11:38        731 DLM3989059.html

例如在DLM3988901.html哪里

<html xmlns="http://www.w3.org/1999/xhtml">
   <head>
      <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
   </head>
   <body>
      <div class="bill" id="DLM3988900">
         <div class="billdetail">
            <div class="explnote" id="DLM3988901">
               <p>DLM3988901 dummy text</p>
            </div>
         </div>
      </div>
   </body>
</html>

并且DLM3989044.html是

<html xmlns="http://www.w3.org/1999/xhtml">
   <head>
      <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
   </head>
   <body>
      <div class="bill" id="DLM3988900">
         <div class="schedule-group">
            <div class="schedule" id="DLM3989039">
               <div class="schedule-provisions">
                  <div class="part" id="DLM3989044">
                     <p>DLM3989044 dummy content</p>
                  </div>
               </div>
            </div>
         </div>
      </div>
   </body>
</html>
