Node.js中的XML(使用javascript）

XML in Node.js (Using Javascript)

本文关键字：使用 javascript XML js 中的 Node      更新时间：2023-09-26

我已经将模拟的XML数据存储在硬盘上(称为simmedData.xml(。 我也有通过Web端点(http://localhost:8079/realData(提供的"真实"数据("真实"数据是动态的(。

XML文档的格式完全相同，但我想将它们"合并"到一个端点中，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将这些 xml 文档合并在一起？

例如：

simmedData.xml

如果你想做任何类型的智能"XML感知"合并，那么你可能会寻找一个XML解析器来做DOM操作，或者一个XSLT转换器来运行一个样式表来合并两者。我确定节点有libxml/libxslt包装器：

  • XSLT for node.js
  • 节点的 XML 解析器.js

我最近在SO上回答了一个关于XML与XSLT合并的问题，但如果你只是做一个简单的"追加"，那么它就会不那么棘手。
