problema QRegExp

Question

He escrito

QRegExp rx("<img src=\"\\S+\"\\s+width=\"(\\d+)\"\\s+height\"(\\d+)\"\\s+/>");

RegExp con el fin de que coincida

 <img src="file://c/Users/Narek/Desktop/WClub.jpg" width="95" height="113.04" />

tipo de subcadena en una cadena, con el fin de extraer la anchura y la altura. Pero esto no coincide. Por favor, dime lo que tengo mal hecho.

Answer 1

The last \d doesn't take account of the dot inside the number, and you are missing '=' after 'height'.

Answer 2

\d does not match the period in your height.

A regular expression that would work would be something like:

<img src=\"[^"]*\"\s+width=\"(\d+(?:\.\d+)?)\"\s+height=\"(\d+(?:\.\d+)?)\"\s+/>

Also, the obligatory comment that it is a bad idea to parse HTML using Regex.

Answer 3

What about :

QRexExp rx("<img src=[^<]+/\> ");

Hope it helps !
