Merrik Posted May 10, 2011 Share Posted May 10, 2011 Hi, I am having trouble with numbers in strings. I need to read each line and capture just the numbers, some have a decimal points (with no more than two digits after the decimal). Each line has just one number (and may be like 54 or 162 or 1.2 or 10.54) and some text. Any help is appreciated. Thanks Link to comment Share on other sites More sharing options...
UEZ Posted May 10, 2011 Share Posted May 10, 2011 (edited) Here a method with RegEx: #include <Array.au3> $string = "Line 1 with 12.55 values" & @LF & _ "Line 2 with 100 digits" & @LF & _ "2011 is the year of the 10.2 winners" $aNumbers = StringRegExp($string, "[\d.]+", 3) _ArrayDisplay($aNumbers, "Filtering numbers off the string") Br, UEZ Edited May 10, 2011 by UEZ Please don't send me any personal message and ask for support!

dufran3 Posted May 10, 2011 Share Posted May 10, 2011 Dangit UEZ...I was working on a n00b style version...not because he is a n00b, but because I am...haha...anyway...here is another way that it could be done. $String = 'Alpha123.5' $NumString = '' $array = StringSplit($String,'') For $i = 1 to $array[0] If StringisDigit($array[$i]) Then $NumString &= $array[$i] Else If StringinStr($array[$i],'.') Then $NumString &= $array[$i] EndIf EndIf Next MsgBox(0,'',$NumString) Link to comment Share on other sites More sharing options...

somdcomputerguy Posted May 10, 2011 Share Posted May 10, 2011 Your way dufran3 is close to what I came up with. I'm pretty novice at this too.. #include <String.au3> #include <Array.au3> $teststring = "this is 1 line not 25 lines of text." $teststringarray = _StringExplode($teststring, " ", 0) ;_ArrayDisplay($teststringarray, "StringExplode 0") For $a = 0 To UBound($teststringarray) - 1 If Number($teststringarray[$a]) > 0 Then ConsoleWrite($teststringarray[$a] & " is a number." & @LF) Next - Bruce /*somdcomputerguy */ If you change the way you look at things, the things you look at change.

GEOSoft Posted May 10, 2011 Share Posted May 10, 2011 Using a modified part of the string from UEZ $sStr = "2011 is the year of the 10.234 winners" $aNums = StringRegExp($sStr, "([\d]+\.?\d{0,2})(?:\d)*", 3); Create a 0 based array of the numbers in the string to a maximum of 2 decimal places If NOT @Error Then ;; do what you want with those numbers in here EndIf George Question about decompiling code?

somdcomputerguy Posted May 10, 2011 Share Posted May 10, 2011 I also look forward to other peoples example codes. It is a good thing for the learning curve, especially in a thread like this. - Bruce /*somdcomputerguy */ If you change the way you look at things, the things you look at change.

UEZ Posted May 10, 2011 Share Posted May 10, 2011 (edited) Well, I'm also a RegEx novice and I'm trying to keep it as simple as possible. Such kind of threads are good to exercise on RegEx and learn from the pros. Br, UEZ Edited May 10, 2011 by UEZ Please don't send me any personal message and ask for support! I will not reply!

GEOSoft Posted May 10, 2011 Share Posted May 10, 2011 And you were very close. Actually it would have worked fine except for the part where he wanted it resticted to 2 decimal points. In fact the SRE you used would be good if he was willing to handle the decimal places at a later stage using Round(). George Question about decompiling code?
