Feature Request: Html parsing and xpath #220

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
Would be really great to get support for fetching a URL, parse it's HTML 
contents into a DOM (look at .net HtmlAgilityPack) and be able use XPATH.

Is this to create a new project or populate a column or ...?

A concrete use case, perhaps including an example of a real URL that you would 
use for this, would be helpful in understanding what you need.

To keep it simple let say I have a coloumn of search phrases and I want to get 
the first result in Google SERP.

So real world URL: 
http://www.google.se/#hl=sv&source=hp&q=candy&aq=f&aqi=g10&aql=&oq=&gs_rfai=&fp=
7f7a53791ad6dfb5

Using XPATH to get data out of webpages is so much easier than using regexpes.

GREL functions have been added to allow HTML parsing in r1948.
It is now possible to use selector syntax to select DOM elements

e.g.
value.parseHtml().select("a")[0].htmlAttr("href")
