我已经将模拟的 XML 数据存储在硬盘上（称为 simmedData.xml）。我还有通过 Web 端点 ( ) 出售的“真实”数据（“真实”数据是动态的http://localhost:8079/realData）。

XML 文档的格式完全相同，但我想将它们“合并”到一个可用的端点http://localhost:8080/mergedData。

我想使用node.js 来托管mergedData 端点——当请求mergedData 时，有没有一种简单的方法可以将这些xml 文档合并在一起？

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' />

如果您想要进行任何类型的智能“XML 感知”合并，那么您可能会使用 XML 解析器来进行 DOM 操作，或者使用 XSLT 转换器来运行将两者合并的样式表。我确信节点有 libxml/libxslt 包装器：

我最近在 SO 上回答了一个关于XML 与 XSLT 合并的问题，但如果您只是简单地“追加”，那么它会变得不那么棘手。
