如何从FTL读取XML节点并遍历它们

Question

我对FTL相当陌生，并且遇到问题。我必须从FTL代码中读取XML，然后遍历它才能显示数据。问题是FTL上的互联网没有太多的文档，我无法总结如何实现这一目标。以下是我写的示例代码，请让我知道我做错了什么。

XML文件

<response status="success"> 
<threads> 
<thread type="thread" href="/threads/id/4999"> 
<id type="int">4999</id> 
<subject type="string"> 
Testing of the XML and FTL 1 
</subject> 
<message_rating type="float">0.0</message_rating> 
<thread type="thread" href="/threads/id/4999"/> 
<last_edit_time type="date_time">2013-10-01T14:08:04+00:00</last_edit_time> 
<last_edit_author type="user" href="https://stackoverflow.com/users/id/149"> 
</last_edit_author> 
<labels/> 
<board type="board" href="/boards/id/10031"/> 
<views> 
<count type="int">1</count> 
</views> 
</linear> 
<read> 
<count type="int">1</count> 
</read> 
<count type="int">1</count> 

</thread> 
<thread type="thread" href="/threads/id/4999"> 
<id type="int">4998</id> 
<subject type="string"> 
Testing of the XML and FTL 2 
</subject> 
<message_rating type="float">1.0</message_rating> 
<thread type="thread" href="/threads/id/4999"/> 
<last_edit_time type="date_time">2013-10-02T14:08:04+00:00</last_edit_time> 
<last_edit_author type="user" href="https://stackoverflow.com/users/id/149"> 
</last_edit_author> 
<labels/> 
<board type="board" href="/boards/id/10031"/> 
<views> 
<count type="int">2</count> 
</views> 
</linear> 
<read> 
<count type="int">1</count> 
</read> 
<count type="int">1</count> 

</thread>

我想提出一个REST调用返回上面的XML，而我写的FTL的代码如下。

有了FTL响应，我需要获取主题，视图计数和论坛URL。

<#assign active_board = restadmin("/boards/id/10031/threads")> 

<!-- I AM NOT SURE HOW TO ITERATE THORUGH THE XML AND GET THE LIST OF ABOVE MENTIONED THINGS I NEED AND DISPLAY IT ON FRONT END --> 

<#assign message_list = restadmin("/threads/id/4999").thread.messages> <!--THIS IS ANOTHER REST CALL--> 
     <#assign count = message_list.topic.kudos.count?number> 
     <#list message_list.linear.message as m> 
      <# count = count+m.kudos.count> 
     </#list> 

Answer 1

我已经能够从FTL代码读取XML。这http://freemarker.org/docs/xgui_expose_dom.html帮了很多。我现在可以根据需要从XML读取所有必要的细节。

问题是我没有提供父节点来开始。以下查询工作。

<#assign threads = restadmin("/boards/id/${coreNode.id}/threads?restapi.response_style=view&page_size=10&page=15").threads/> 

我不知道这会有多大帮助，但我发布这个答案仅仅是因为FTL文档太少。
