Re: regex help please
Klaus, I used to work like that, doing little XML files with RegEx and matchText. After working like that for a long time, I came to realize that there was no advantage at all in my case. It was simpler to work with RevXML. The problem with RegEx is all the little cases where it fails. I think you should use RevXML, it might look overkill but it will cut your debug time a lot.

So using the XML external seems to be a bit overkill. Some time ago I found a little reg ex here on the list which I turned into a function and will return me everything inside of a given XML tag: ... tag1bla bla/tag1 tag2more bla bla/tag2 ... So with this text above in tText and tag2 int tTag: function mk_getXMLdata tText, tTag get matchText(tText,(?s) tTag (.*?)/ tTag ,tValue) return tValue end mk_getXMLdata will give : more bla bla So far so good, I even almost understand the reg ex ;-) Now I am looking for another little snippet to (over) write something in(to) a certain TAG, know what I mean? If someone could supply a nifty replacetext snippet that would be great! :-) Thanks in advance!

Wait, didn't we just hear that you can't parse html (or XML) with regexps? *grin* function mk_getXMLdata tText, tTag get matchText(tText,(?s) tTag (.*?)/ tTag ,tValue) return tValue end mk_getXMLdata Throwing caution to the winds, this probably does something similar to what you want without further regexp voodoo: function mk_replaceXMLdata tText, tTag, tNewText put tText into tValue if matchText(tText,(?s) tTag (.*?)/ tTag ,tValue) then put replaceText(tText, \ tTagtValue/tTag,\ tTagtNewText/tTag) into tValue end if return tValue end mk_replaceXMLdata And remember: zalgo is tony the pony!

Re: regex help please
Klaus, What Andre said. Nonetheless, if you want to continue down the regex path, try something like get matchText(tText,(?s) tTag (.*?)/ tTag ,tValue) replace tTagtValue / tTag with tTagtNewValue / tTag in tText -- Mark Wieder ___ 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

Re: regex help please
Klaus, Since you have control, then instead of RegEx, you can go like mynode nodecontent /mynode All in different lines, then, you can just use lineOffset to find the start node and the end node and copy or replace the data between those lines. It is easier than RegEx.

You might take a look at the code again. In both cases you hand in the whole XML text, the tag you want to replace, and the value you want to stuff into it. The matchText function gets the current value in that tag. Mark's replace above (or my replaceText) replace that, and return the result. -Ken ___ 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

Mark Weider's code will work for you, Klaus… the tValue is something that the matchText function FILLS with the current text inside the brackets, so you don't need to know it ahead of time. The (.*?) is a way to capture what is between the tags, and the 3rd+ parameters to he matchTextFunction are variables that are provided to the function that get filled with whatever is being captured. The matchText function returns either 'true' (if it can find what you are looking for) or 'false') if it can't. Mark's code above assumes a 'true' result by using get. Here's an example that takes into account the possibility that you may not match what you're looking for: put tagHello/tag into tData if matchText(tData,(?s)tag(.*?)/tag,tValue) = true then put tValue -- Since this matches, you'll get Hello in the msg box else put No Match end if Ken Ray Sons of Thunder Software, Inc.
