QRegExp capture and replace

Question

I have a string

    @echo Setting environment for using the GDAL Utilities.
    set GDAL_PATH="G:\MapTiler"
    @echo GDAL path is %GDAL_PATH%.
    set PATH=%GDAL_PATH%;%PATH%

in this i want to extract "G:\MapTiler" and replace it with "c:\gdal\bin"

for that i need QRegExp.

thanks

You should use the QString::replace() method for this:

QString gdalPath;
gdalPath.replace(QRegExp("G:\\MapTiler"),"c:\\gda\\bin");

But if the string being replaced does not even change, do not use regex, use string replace:

gdalPaht.replace("G:\\MapTiler","c:\\gda\\bin");

Edit for changing paths:

QString::replace(QRegExp("set GDAL_PATH=\"[^\"]*\""),"set GDAL_PATH=\"c:\\gda\\bin\"");
