QRegExp help

[bandito]

I would like to remove all lines from a QString that have text and keep the ones that are numbers.

Prior to running a regexp my QString output be as so:

hello
1
world
2

hello
1
world
2

To copy to clipboard, switch view to plain text mode 

if I ran something like

QString.remove(QRegExp("(^[a-z]*\\n$)"))

QString.remove(QRegExp("(^[a-z]*\\n$)"))

To copy to clipboard, switch view to plain text mode 

my QString output would be:

1
2

1
2

To copy to clipboard, switch view to plain text mode

So? Have you tried the solution you propose? Did you get the expected result?

No. I ended up just convert it to a QStringList and doing it line by line. The only reason I wanted to do it with a regexp was to save some lines of code.

Well, that would have only saved one line of code compared to using QString::split() and QStringList::filter()

Obviously not being paid per line of code.
