D24982: Small improvements in some XML files

[Nibaldo González]

nibags added a comment.


  I had also thought about using `QRegularExpression::DontCaptureOption`, which is equivalent to using `(?:...)`, but I wasn't sure how much the real improvement in performance is. However, disabling captures avoids allocating unnecessary QString for each capture.
  
  One option would be to add a **capture** or **dontCapture** attribute to enable or disable captures for RegExpr rules. Also, captures could be enabled or disabled in all RegExpr rules using the **<general>** group, adding an element for that.
