Extracting file path from String

Gagan

Hi everyone,

I am using Qt 5.8 and having a query regarding extracting a substring from main string.
here substring is the file path of file on server located in local LAN.

Actual String is

QString str = "My comment given for the file#\\192.168.1.1\project\name\file.pdf#".
I want the output as "\192.168.1.1\project\name\file.pdf"

I tried with section function and qDebug() to console but its removing backslashes. its showing me like this

"\192.168.1.1 project name file.pdf".

Please Help !

@Gagan Is the value you need always sorrounded by #, like the example you provided? If so you may want to use regular expresions using QRegularExpression.

@Pablo-J.-Rogina
Thanks so much for your suggestion but m not much familiar with QRegularExpression.
Still anyways, I have solved the same thing in SQl query itself while loading the resultset.

Thanks again !

Hi @Gagan,

QString::section() should work fine. I suspect you're being tripped up by the need for escaping in string literals?

Here's a working example:

QString str = "My comment given for the file#\\\\192.168.1.1\\project\\name\\file.pdf#";
qDebug().noquote() << str;
qDebug().noquote() << str.section('#',1,1);

Output:

My comment given for the file#\\192.168.1.1\project\name\file.pdf#
\\192.168.1.1\project\name\file.pdf

Cheers.
