If i run this regular expression search in a text editor (I have used TextPad), the correct result is shown, but Finalbuilder returns No Match found. But as far i as i can see a have only used expressions that the TRegExpr uses.
Is the actual expression you want to match just “.+” (ie “any string”)? If so, just trim off the backslashes and it should work fine. FinalBuilder does not required any kind of \RegExp\ syntax to know it’s looking at a regular expression (as long as you enable regular expressions.) In particular, it will treat . as an escaped period (ie an exact match for “.”.)
The quick answer to your problem is that - because the files are XML - it is probably a lot easier to use the XML actions to edit them. If you use a File Iterator action (to iterate the FileSet) with an Edit XML File Action as the child, you can set the XML action up like this:
XPath = //setting[@name=‘DotNetNukeUrl’]/value Attribute = Value = %DotNetNukePath%
Alternatively, if you absolutely have to use a Regular Expression for some reason, you can set it up as shown in these screenshots. Let me know if you’d like an explanation of the syntax I’ve used.
