newphpnoob13 Posted January 3, 2013 Share Posted January 3, 2013 Hello Everyone, I have a log file in txt format. Here's a part of it: ================================================ [Jan 25 2012 11:47:31] - ID2PDF v.2.6 (ID2PDF.jsx) General options: [default] (ID2PDF_options.xml) ================================================ Loaded options from XML file: '/Thisis/some/Users/sumuser/Desktop/SM_Folder/ESQ/Virtual_Proof_ESQ/processing/ID2PDF_options.xml extendedPrintPDF started Postfix '3.0' was append from file 'ESQ030112ELAM_lo-metadata.xml' for file: '/Thisis/some/Users/sumuser/Desktop/SM_Folder/ESQ/Virtual_Proof_ESQ/processing/someFile.indd printPDF started PDF Export Preset: Some preset PDF file created: ''/Thisis/some/Users/sumuser/Desktop/SM_Folder/ESQ/Virtual_Proof_ESQ/processing/someFile.pdf'. File someFileName.xml removed postprocessingDocument started INDD file removed: '/Thisis/some/Users/sumuser/Desktop/SM_Folder/ESQ/Virtual_Proof_ESQ/processing/someFile.indd ================================================ [Jan 25 2012 15:18:23] - ID2PDF v.2.6 (ID2PDF.jsx) General options: [default] (ID2PDF_options.xml) ================================================ Loaded options from XML file: ''/Thisis/some/Users/sumuser/Desktop/SM_Folder/COS/Contract_Proof_COS/processing/ID2PDF_options.xml extendedPrintPDF started Postfix '8.1' was append from file 'ESQ030112Politics_Russia_lo-metadata.xml' for file: '/Thisis/some/Users/sumuser/Desktop/SM_Folder/COS/Contract_Proof_COS/processing/oneMoreFile.indd printPDF started PDF Export Preset: Hearst PDF 1.6_1_16_08 PDF file created: '/Thisis/some/Users/sumuser/Desktop/SM_Folder/COS/Contract_Proof_COS/processing/oneMoreFile.pdf'. File oneMoreFile.xml removed postprocessingDocument started INDD file removed: /Thisis/some/Users/sumuser/Desktop/SM_Folder/COS/Contract_Proof_COS/processing/oneMoreFile.indd And it continues this way. I am supposed to catch the 3 letter words like ESQ and COS (appearing in the path of file on very first line of entry ONLY) in an array. I'm not able to think of a logic/create a RegEx because the user name may change often. Can anyone give me heads up on how I could possibly achieve this? Would appreciate the help.

requinix Posted January 3, 2013 Share Posted January 3, 2013 So you're looking for the "COS" in Loaded options from XML file: '/Thisis/some/Users/sumuser/Desktop/SM_Folder/COS/Contract_Proof_COS/processing/ID2PDF_options.xml' Is the folder structure always the same? At least in terms of the SM_Folder/*? Then it's as simple as /^Loaded options from XML file: '/.*/SM_Folder/([a-z]{3})/Contract_Proof_\1/processing/ID2PDF_options.xml'$/im (\1 being a backreference to the [a-z]{3} matched earlier) If the folder structure varies much more than that then how do you know where to find the "COS"?

newphpnoob13 Posted January 3, 2013 Author Share Posted January 3, 2013 The structure would remain the same from ../Desktop/ onwards. However, the RegEx you gave does not seem to work either.

requinix Posted January 3, 2013 Share Posted January 3, 2013 Change the delimiters to something else, and modify the regex so it will also return the ESQ line (and others that aren't COS).

newphpnoob13 Posted January 4, 2013 Author Share Posted January 4, 2013 Okay. So, now I've got to /^Loaded options from XML file: '\/.*\/SM_Folder\/([a-zA-Z])\/[a-zA-Z]_Proof_\1\/processing\/ID2PDF_options.xml'$/im But, I get an EMPTY array. Still better than getting an error. But, how do I resolve this to get my 3 letter word? Note: If I take off the '\' from \/([a-zA-Z])\ I get a unknown modifier '(' error.

requinix Posted January 4, 2013 Share Posted January 4, 2013 The [a-zA-Z] you added will only match one character. You'd need a + to match more than one. $regex = '#^Loaded options from XML file: \'/.*/SM_Folder/([a-z]{3})/\w+_\1/processing/ID2PDF_options.xml\'$#im'; preg_match_all($regex, $text_from_file, $matches) && var_dump($matches); works for me (with the wonky quotes in the example text fixed).

newphpnoob13 Posted January 4, 2013 Author Share Posted January 4, 2013 @requinix: This is the data which is more closer to my original file. I messed up the quotes a little bit in my original post. ================================================ [Jan 25 2012 11:26:03] - ID2PDF v.2.6 (ID2PDF.jsx) General options: [default] (ID2PDF_options.xml) ================================================ Loaded options from XML file: '/This/folder/Users/userName/Desktop/SoMe_Folder/ABC/SomeName_Proof_ABC/processing/someFile_options.xml extendedPrintPDF started Postfix '4.4' was append from file 'ABCFileName.xml' for file: /This/folder/Users/userName/Desktop/SoMe_Folder/ABC/SomeName_Proof_ABC/processing/ABCFileName.indd PDF file created: '/This/folder/Users/userName/Desktop/SoMe_Folder/ABC/SomeName_Proof_ABC/processing/ABCFileName.4.pdf'.

I'm trying everything and it doesnt seem to help. P.S. I've ignored stuff from the file that's not required for this particular problem.

requinix Posted January 4, 2013 Share Posted January 4, 2013 Well, the regex specifically says "SM_Folder" while your output has "SoMe_Folder", and the regex also expects "ID2PDF" where your output has "someFile". If you don't know those names for sure then use a wildcard. Also I'm removing the leading slash from the filename, just in case. /^Loaded options from XML file: '.*\/([a-zA-Z]{3})\/[a-zA-Z]+_Proof_\1\/processing\/.*_options.xml$/im When a regex doesn't match, make it more and more generic (more wildcards, fewer literal characters) until it matches. Then figure out what you may or may not need to add back to get the exact results you need.

newphpnoob13 Posted January 4, 2013 Author Share Posted January 4, 2013 @requinix: Resolved the problem a little while back. But, saving this code for future reference. Thanks a lot for your inputs!!
