XSLT脚本摆脱嵌套的子节点

Question

Input XML:

<tree>
  <node name="GrandParent">
    <node name="Parent1">
      <qualifier>Fat</qualifier>
    </node>
    <node name="Parent2">
      <qualifier>Slim</qualifier>
      <node name="Child1">
        <qualifier>Tall</qualifier>
      </node>
      <node name="Child2">
        <qualifier>Short</qualifier>
      </node>
    </node>
  </node>
</tree>

Required output:

<tree>
  <node name="GrandParent-Parent1">
    <qualifier>Fat</qualifier>
  </node>
  <node name="GrandParent-Parent2">
    <qualifier>Slim</qualifier>
  </node>
  <node name="GrandParent-Parent2-Child1">
    <qualifier>Tall</qualifier>
  </node>
  <node name="GrandParent-Parent2-Child2">
    <qualifier>Short</qualifier>
  </node>
</tree>

I want to get an optimized XSLT script for achieving the same. Please help me.

(Note: The input given is just a sample. The child nodes can be nested to any depth. )

Here are some hints to point you in the right direction:

• Get to know the <xsl:template> and <xsl:apply-templates> instructions; they will be the backbone of a solution for this problem.
• Get to know the `concat()' function, as well. This will assist with the naming scheme change you are looking to make.
• Become comfortable with XPath axes (in particular, parent::* , ancestor::* , and relative XPaths like ../ or ../../ .

Additionally, take a look at this question (and subsequent answers) - it might be useful in your scenario, as well: Merge successive descendant nodes into one

It sounds like you have a hard deadline tomorrow, but going forward, I would recommend taking the time to read good materials on XSLT/XPath. You can find several here: https://stackoverflow.com/questions/339930/any-good-xslt-tutorial-book-blog-site-online/341589#341589
