how can get all links with QT from a web page?

[ChineseAlexander]

I do not need a window,but I hope it can parse some javascript written URL for too many web page give out the URL not so directly.

How should I do?

You can parse anything you like with QString and QRegExp.

Thanks, but my problem is that, it seems not so easy to deal with some javascript which make the full real url.

like below:

<a href='javascript:get_url()'>something</a>


by the way, is there any easy way to retrive a page content source?

like
QSomeClass q("http://google.com");
q.GetText()
??

We are touching multiple subjects here. Please provide details on what you want to achieve and what you have already tried. If you want contents of a remote page, use QNetworkAccessManager or QHttp to download it. You can execute javascript code from a webpage but you have to extract it first from the page and then feed it to QScriptEngine.

hello wysota,

I have done some work about retrive links from a web page with your hint,use QHttp & QRegExp.But it lays still a big problem is how to retrive some URL which is composite with javascript. The QScriptEngine is not so easy to use.

Some days ago,I may see a interface function like xxxURLs() which may be contained in QWebKit Classes.But now,I just can't find it again. Is it a memery mistake?

Do any one has any idea about how to Get All links completely?

Thanks a lot,
