RegEx is a slower technique almost every time. The larger the text block, the more hits, and the larger the number text blocks all add to the demand. Regex is an engine that actually scans back and forth through a text block and follows rules. The simpler the rules you give it, the shorter the processing time. Using Rev's chunking ability will always about 10-100 times faster. However, a field of 100 lines will not be noticeable. I use some heavy regEx to parse web pages everyday, every minute because I need pin-point accuracy and data mining vs fasted execution. Lots of rules, lots of steps. Chunking just won't do it without a lot of 'IF' statements. In Rev, this is actually very fast. You can extract only the words on the lines where they live by: repeat for each line LNN in textBlock repeat for each word WRD in LNN put WRD & space after newTextBlock end repeat delete last char of newTextBlock put cr after newTextBlock end repeat delete last char of newTextBlock Of course this example strips the punctuation and tabs Jim Ault Las Vegas _______________________________________________ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution
