Node.js中的XML (使用Javascript)

Question

我已经将模拟的XML数据存储在硬盘(称为simmedData.xml)中。我还获得了通过web端点(http://localhost:8079/realData)获得的“真实”数据(“真实”数据是动态的)。

XML文档的格式完全相同，但我希望将它们“合并”到http://localhost:8080/mergedData可用的一个端点中。

我想使用node.js托管mergedData端点--在请求mergedData时，是否有一种简单的方法将这些mergedData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' />

Answer 1

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

• 用于node.js的XSLT
• 用于node.js的XML解析器

我最近在这里回答了一个关于XML与XSLT的合并的问题，但是如果您只做一个简单的“附加”，那么它就不会那么棘手了。
