reading a hex number and freq Posted by miguelrab (miguelrab), 28 November 2006 Hi,I need little help. can u please tel me how can I read hex numbers between a range of number of digits e.g how can i read four to 30 digit hex numbers from large amount of given data by using tcl. Cheers Posted by admin (Graham Ellis), 28 November 2006 I'm not clear that I understand your specification exactly. Can you post up a sample of the data and desired result, and also the code you've tried so far? ThanksPosted by miguelrab (miguelrab), 28 November 2006 For Example if I have data bjhkhihhhmnnoj kpi boot:0x08Ahiyiyin boot:0x897Abjjhjbjboot:0x124456A Posted by miguelrab (miguelrab), 28 November 2006 for example if i have datahgfsdhfghdgfrboot:0x122hjhkhknkboot:0x122Agugugu boot:0x89A676Biiu9iuou output should be: boot: 0x122A boot:0x89A676B so it looks at whole data which is string and takes out hex numbers from it which should are of minimum 4 digits and maximum 30 digits. It ignores all the other numbers. cheers Posted by admin (Graham Ellis), 28 November 2006 Ah .... with you now. Have a look at the regexp command and that should do the trick for you. Capture all matches to 0x followed by hex digits ...Posted by miguelrab (miguelrab), 29 November 2006 Hi grahamBut how can I define the range of digits using regexp it only handles fixed number of digits that i define. Posted by admin (Graham Ellis), 29 November 2006 Use a count such as {4,30} if you want to match between 4 and 30 of the preceeding element.Use [0-9a-fA-F] to specify "any hex digit".
