[webkit-gtk] webkit_dom_element_get_elements_by_tag_name doesn't work properly

Fri Dec 13 02:33:28 PST 2013

Sorry, I was very busy and I couldn't see the mail list.

Finally I fixed the error, it was my fault. As you say I should use webkit_dom_document_get_elements_by_tag_name() insted of webkit_dom_element_get_elements_by_tag_name(). But I had other problem, I didn't wait until webpage load finish. 

I explain my problem at StackOverflow and there explain the solution. It can useful for other people so I put the link:

Thanks everyone.
