Hi,

I have the html source of a URL in a QString. How could I get all the links with QRegExp?

Many thanks and sorry for my english!

Start with the documentation of QRegExp

Qt Code:

Switch view

QRegExp rx("(\\d+)");
 QString str = "Offsets: 12 14 99 231 7";
 QStringList list;
 int pos = 0;
 
 while ((pos = rx.indexIn(str, pos)) != -1) {
     list << rx.cap(1);
     pos += rx.matchedLength();
 }
 // list: ["12", "14", "99", "231", "7"]

QRegExp rx("(\\d+)");
 QString str = "Offsets: 12 14 99 231 7";
 QStringList list;
 int pos = 0;

 while ((pos = rx.indexIn(str, pos)) != -1) {
     list << rx.cap(1);
     pos += rx.matchedLength();
 }
 // list: ["12", "14", "99", "231", "7"]

To copy to clipboard, switch view to plain text mode

And then simply write a expression which fits your needs. It isn't so complicated... And if you don't know use google with "regular expressions link href"!
