Harry Potter

xpath.js

An xpath module for node, written in pure javascript.

Originally written by Cameron McCormack (blog).

Prepared as a node module by Yaron Naveh (blog, twitter).

Install

Install with npm:

npm install xpath.js

xpath.js is xml engine agnostic but I recommend to use xmldom:

npm install xmldom

Your first xpath:

````

javascript

	var select = require('xpath.js')

	  , dom = require('xmldom').DOMParser



	var xml = "Harry Potter"

	var doc = new dom().parseFromString(xml)    

	var nodes = select(doc, "//title")

	console.log(nodes[0].localName + ": " + nodes[0].firstChild.data)

	console.log("node: " + nodes[0].toString())

```



-->



	title: Harry Potter

	Node: Harry Potter



Get text values directly

```

javascript 

    var xml = "Harry Potter"

    var doc = new dom().parseFromString(xml)    

    var title = select(doc, "//title/text()")[0].data   

    console.log(title)

```

  

-->

    

    Harry Potter



Namespaces

```

javascript  

	var xml = "Harry Potter"

    var doc = new dom().parseFromString(xml)    

    var node = select(doc, "//*[local-name(.)='title' and namespace-uri(.)='myns/']")[0]

    console.log(node.namespaceURI)

```
