regex - Qt 4.8.4 MAC Address QRegExp -

-

i'm trying qt match mac address ( 1a:2b:3c:4d:5e:6f ) using qregexp. can't seem match - doing wrong?

i forcing try , match string:

"48:c1:ac:55:86:f3"

here attempts:

// define regex match mac address //qregexp regexmacaddress("[0-9a-f]{1,2}[\.:-]){5}([0-9a-f]{1,2}");  //qregexp regexmacaddress("[0-9a-f]{0,2}:[0-9a-f]{0,2}:[0-9a-f]{0,2}:[0-9a-f]{0,2}:[0-9a-f]{0,2}:[0-9a-f]{0,2}");  //regexmacaddress.setpatternsyntax(qregexp::regexp);  // ensure hexadecimal characters upper case hwaddress = hwaddress.toupper();  qdebug() << "string match: " << hwaddress << "matched it: " << regexmacaddress.indexin(hwaddress) << " exact match: " << regexmacaddress.exactmatch(hwaddress);  // check mac address format if ( regexmacaddress.indexin(hwaddress) == -1 ) {

in first example opening bracket missing , \. incorrect (read help explanations), in both a-f matches nothing, due 'a' > 'f'.

the correct answer can find in comment of kenrogers, i'll duplicate you:

([0-9a-f]{2}[:-]){5}([0-9a-f]{2})

if want match . should use:

([0-9a-f]{2}[:-\\.]){5}([0-9a-f]{2})

if want match lower case characters, should use:

([0-9a-fa-f]{2}[:-\\.]){5}([0-9a-fa-f]{2})
