Hello, I have a couple of hundred pages of text where I need to extract out a different string.
The ending of each string I need has the same ending skyrider1 The beginning of each string is the same selkirkst The middle of each string can be any text. The problem is that within each line where a string exists there are several strings that have the same beginning selkirkst but none of the have the correct ending skyrider1. My thoughts are to find ending of the string first and then work backwards to the first beginning string. I created the following example which is gibberish but should make this clearer... this is the string I want to extract from the line given is *selkirkst is placed in the second **skyrider1* Use the *selkirkst* function to check whether a *string* contains a specified pattern. If *selkirkst* includes a pair of parentheses, the position of the substring matching the part of theregular expression inside the parentheses is placed in the variables in the *positionVarsList*. The number of the first character in the matching substring is placed in the first variable in the positionVarsList, and the number of the last *selkirkst is placed in the second **skyrider1*. Additional starting and ending positions, matching additional parenthetical expressions, are placed in additional pairs of variables in thepositionVarsList. If the *selkirkst* function returns false, the values of the variables in the positionVarsListare not changed. The string and regularExpression are always case-sensitive, regardless of the setting of the caseSensitive property. (If you need to make a case-insensitive comparison, use "(?i)" at the start of the regularExpression to make the match case-insensitive.) The next line will not have *is placed in the second* but some other text *selkirkst* ???? *skyrider1* I am not sure if this explains it well enough but I believe a regex expression could be used (or perhaps a matchChunk) to extract the correct string from each line of text. Any suggestions? thanks, Glen _______________________________________________ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
