Question

这是我之前提出的问题的扩展 - XSLT 1.0 Grouping with multiple elements with same name 输出格式已更改，因此重新发布。

我的XML看起来像 -

<resultset>
    <hit>
        <content>
            <ITEM>
                <TITLE>Office Cleaning1</TITLE>
                <DESCRIPTION>blah blah blah</DESCRIPTION>
                <Hierarchy>level1A~level2A~level3A</Hierarchy>
                <Hierarchy>level1B~level2B~level3B</Hierarchy>
            </ITEM>
        </content>
    </hit>
    <hit>
        <content>
            <ITEM>
                <TITLE>Office Cleaning2</TITLE>
                <DESCRIPTION>blah blah blah</DESCRIPTION>
                <Hierarchy>level1A~level2A~level3B</Hierarchy>
            </ITEM>
        </content>
    </hit>
    <hit>
        <content>
            <ITEM>
                <TITLE>Office Cleaning3</TITLE>
                <DESCRIPTION>blah blah blah</DESCRIPTION>
                <Hierarchy>level1A~level2B~level3C</Hierarchy>
            </ITEM>
        </content>
    </hit>
    <hit>
        <content>
            <ITEM>
                <TITLE>Office Cleaning4</TITLE>
                <DESCRIPTION>blah blah blah</DESCRIPTION>
                <Hierarchy>level1A~level2B~level3B</Hierarchy>
                <Hierarchy>level1A~level2B~level3C</Hierarchy>
            </ITEM>
        </content>
    </hit>
    <hit>
        <content>
            <ITEM>
                <TITLE>Office Cleaning5</TITLE>
                <DESCRIPTION>blah blah blah</DESCRIPTION>
                <Hierarchy>level1B~level2B~level3B</Hierarchy>
            </ITEM>
        </content>
    </hit>
</resultset>

请注意，有多个层次结构元素是level1~level2~level3的串联字符串我希望将其转换为类似的内容 -

<TREE>
<LEVELS>
<LEVEL1 name="level1A">
 <LEVEL2 name="level2A">
   <LEVEL3 name="level3A">
      <ITEM Name="Office Cleaning1"/>
   </LEVEL3>
   <LEVEL3 name="level3B">
      <ITEM Name="Office Cleaning2"/>
   </LEVEL3>
 </LEVEL2>
 <LEVEL2 name="level2B">
   <LEVEL3 name="level3B">
        <ITEM Name="Office Cleaning4"/>
   </LEVEL3>
   <LEVEL3 name="level3C">
      <ITEM Name="Office Cleaning3"/>
      <ITEM Name="Office Cleaning4"/>
   </LEVEL3>
 </LEVEL2>
</LEVEL1>
<LEVEL1 name="level1B">
  <LEVEL2 name="level2B">
    <LEVEL3 name="level3B">
        <ITEM Name="Office Cleaning1"/>
        <ITEM Name="Office Cleaning5"/>
    </LEVEL3>
  </LEVEL2>
</LEVEL1>
</TREE>

基本上每个项目都有多个与之关联的层次结构。我需要将它们组合在一起，并将每个级别组合在一起。

我实际上可以将输入XML中HIERARCHY元素中的值更改为可能更容易提取的任何格式。对于例如我可以看起来像LEVEL1：level1A~LEVEL2：level2A~LEVEL3：level3A 但我无法添加新元素。

Answer 1

我自己开始工作了。忽略额外的命名空间。我编辑了层次结构字段，使其具有level1的格式：value~level2：value~level3：易于子字符串的值。

我相信有更好的方法，但这对我有用。
