texte = Cool, that's the answer that I have been waiting for.I realize my example was flawed from a hurried copy and paste error, but that's because I was in a hurry to type in an example, as I have spent way too much time trying to get this to work.Firstly, grep didn't even work in the WebCatalog that I bought a week and a half ago. I was told after the fact that the syntax for what I bought is regexp not grep. . .which is not in any of the manuals or online data. In fact the online docs say that 4.0 has grep. I put a [version] tag on my page to make sure I was running 4.0. . .I was. . . Maybe it should say new in 4.1 - grep, with 4.0 being regexp.Lost a full night to that one.And then some more hours trying to get around the ampersand thing. I know Ampersand is not allowed in browser stuff, but, webcat source never gets to the browser so I thought, since it is called grep I could use the standard \ to delimit a reserved character. Who woulda thunk that I should use [url] in a grep expression.If I do use [url] to expand bad things, how do I search for [url] using grep, if that is reserved instead? Do i have to use [raw][url][raw]? Will that even work????Seems to me that \& is more to the point for a regex search expression.Thanks for the quick response on this pseudo holiday.
