put numToChar(255) into m replace "<#B>" with m replace "<#E>" with m put zero into c repeat for each item k in raw_input add 1 to c if c mod 2 is zero then put k & kr after h end if end repeat delete char -1 of h put h into clean_output

To: "How to use LiveCode" <use-livecode@lists.runrev.com> Date: Tuesday, August 2, 2011, 3:01 AM The recipe I (learned here and) use with extracting specific HTML / XML elements is to get the specific target elements on their own line, remove the unwanted lines and then move the target string items in the remaining lines out into a separate variable - something like... 1. Get the target elements into their own line by prefixing the opening tag with return, using: replace "<#B>" with return & "<#B>" in theSource 2. Get the closing tag onto its own line by adding a return suffix, using: replace "<#E>" with "<#E>" & return in theSource 2. Remove the unwanted lines, (that lack the specific opening tag) using: filter theSource with "<#B>" 3. Delimit the line into items at the '>' character, using: set the item delimiters to numtochar(62) 4. Iterate through the list to extract the string, using: repeat for each line l in theSource put item 2 and return after theExtract end repeat 5. Clean-up the extract of any extra returns, using: filter theExtract without empty If (my pre-coffee brain worked) theExtract should contain the tagged strings in theSource. ...hmmm, talking of coffee...
