[SOLVED] How to use "(" character in QRegExp to find matches in string?
-
I have some HTML code and I want to get links from it. HTML code I have is in QString format and I want to split it by matches as href=" and url(. If I do something like:
@QStringList lst;
QRegExp regexp("\href=""); // " works ok
lst = htmlCode.split(regexp);
@
everything works and it split my html string (later I will cut the rest and have just link without text after second " character in href="")
but if I do
@QStringList lst;
QRegExp regexp("\url("); // ( fails
lst = htmlCode.split(regexp);
@
string doesn't split for some reason, I see problem is with ( but I don't know why. I tried do it as regexp("\url("); and by ascii as regexp("\url\50") (wondering why it takes numbers as octal) neither worked, it just returns original string.I am still newbie in Qt so please help me or if there is better way to extract links from html code than I want to use I'll be happy if you guys tell me.

You need to double the backslash before the (. The \ is an escape character in both C++ and in regexps, so to get a single \ into your regexp, you need two in your C++. To get a double \ into your regexp (to match a literal ), you need four in C++...
