如何合并具有“同一个父亲"的两个节点并且有一个精确的“方法"；序列(使用 XSLT)? [英] how to merge two nodes having "the same father" and having a precise "method" sequence (using XSLT)?

问题描述

我需要合并两个节点MANHATTAN:

I need to merge the two nodes MANHATTAN:

因为我们的系统规则如下:

because our system rule is the following:

"CREATE A + MODIFY A" 仍然是 "CREATE A 与合并的属性"

"CREATE A + MODIFY A" is still a "CREATE A with the merged attributes"

输入文件:

<?xml version="1.0" encoding="UTF-8"?>
<world>
<COUNTRY id="USA" >
  <STATE id="NEW JERSEY">
     <CITY id="NEW YORK" method="modify">


        <DISTRICT id="MANHATTAN" method="create">
           <attributes>
              <population>99 </population> 
              <income> 10000</income>
           </attributes>
        </DISTRICT>

        <DISTRICT id="MANHATTAN" method="modify">
           <attributes>
              <temperature>78</temperature>
              <income>15000</income>
              <information>suburb of newyork</information>
           </attributes>
        </DISTRICT>

     </CITY>

  </STATE>

预期输出:

 <?xml version="1.0" encoding="UTF-8"?>
 <world>
 <COUNTRY id="USA" >
  <STATE id="NEW JERSEY">
     <CITY id="NEW YORK" method="modify">

        <DISTRICT id="MANHATTAN" method="create">
           <attributes>
              <population>99 </population> 
              <temperature>78</temperature>
              <income>15000</income>
              <information>suburb of newyork</information>
           </attributes>
        </DISTRICT>

     </CITY>
 </STATE>
</COUNTRY>
</world>

请帮忙，我刚刚开始使用 XSLT，在 Perl 或 Python 中完成需要几个小时.

Please help, I have just began XSLT and doing it in Perl or Python will takes hours.
