node-wgxpath
Wicked Good XPath is a fast implementation of document.createExpression and document.evaluate (DOM3-XPath) in pure Javascript.
Version
x.y.z
: x.y
refers to the Wicked Good XPath revision when wgxpath.install.js
was built; z
refers to any improvements to this package.
I'm pretty lazy, so I don't build Wicked Good XPath myself. When the pre-compiled wgxpath.install.js is updated, I'll update this package.
Installation
Install with npm:
npm install wgxpath
Make sure things are working:
node node_modules/wgxpath/word_of_the_day.js
Example
This example scrapes the Merriam-Webster Word of the Day. This code can also be found in word_of_the_day.js
. Be sure to install jsdom 3.x before running the example.
$ npm install jsdom@"<4"
var wgxpath = ;var jsdom = ; var url = 'http://www.merriam-webster.com/word-of-the-day/';var expressionString = '//*[@id="content"]/div[3]/ul/li[1]/strong'; jsdom;
