CANHAZ is a simple scraping tool

Give it a URL and an XPath expression and it will fetch the URL, parse it, and return a JSON structure of the results of the XPath selection.

Parameters

• url: the URL to fetch
• xpath: the xpath expression

Example

curl 'http://localhost:8080/?url=http://example.com/&xpath=//img/@src'

Results

A successful request will return something like:

{"results" : {"text": "foo.jpg"}}

A bad xpath expression will return:

{"error" : "bad xpath"}

And HTTP errors will get passed along as well.

Future Plans

• CSS Selectors
• multiple xpath expressions
• multiple URLs
• async callbacks
