Node.js中的XML（使用Javascript）

Question

我已經將模擬的XML數據存儲在硬盤上（稱為simmedData.xml）。 我還通過Web端點（ http://localhost:8079/realData ）獲得了“真實”數據（“真實”數據是動態的）。

XML文檔的格式完全相同，但我想將它們“合並”到http://localhost:8080/mergedData一個端點。

我想使用node.js來托管mergedData端點 - 在請求mergedData時，是否有一種簡單的方法將這些xml文檔合並在一起？

例如：

simmedData.xml

<site:Tracks xmlns:site='http://mysite/site'>
  <site:track id='1' latitude='37.82091918923291' longitude='128.87375778822812' altitude='9753.6005859375' bearing='10.542624087704585' speedInKnots='454.6067199707031' />
  <site:track id='2' latitude='37.45048387959727' longitude='129.49111126654887' altitude='9144.0' bearing='190.90400586790983' speedInKnots='436.89837646484375' />
</site:Tracks>

Answer 1

如果你想進行任何類型的智能“XML感知”合並，那么你可能會看到一個XML解析器來執行DOM操作或者一個XSLT轉換器來運行一個可以合並這兩者的樣式表。 我確信節點有libxml / libxslt包裝器：

• node.js的XSLT
• node.js的XML解析器

我最近在這里回答了一個關於XML與XSLT合並的問題，但是如果你只是做一個簡單的“追加”那么它就會變得更加棘手。
