Using jQuery to extract data from HTML page

in Using jQuery • 2 years ago

I stumbled across jQuery while during a search for my project that involves parsing and extracting content from HTML pages. I have a collection of xpath strings that identifies the data I would like to extract. Wondering if I could use jQuery for this purpose. If so can someone share with me some samples or share some pointer on how I could achieve this.

Appreciate your time and help

jQuery doesn't use XPath selectors, using CSS style ones instead, however, you should be able to convert most XPath selectors into something equivalent. Then you would load the targetted page and extract the required data:

$(function() {
$.get('target.html', function(data) { // Retrieve the page
data = $(data); // Wrap returned HTML with jQuery
var value = data.find('ul a:first').text(); // Get the text content of first a within a ul
});
});
