.NET Forum / Languages / C# / July 2008splitting string with a string
I have a html page that I retrived and stored in a string and I want to split it based on <td> elements. I know only way you can split using string.split is using characters. The other option is traverse and split. Is there any other way you can split a string using string token itself?

Thanks. > > Use Regex.Split. > > Duh??? Which part didn't you understand? In the RegEx class, there's a Split method. Construct an appropriate regex, and call the Split method. As Pavel mentioned, String also now contains an overload for String.Split which takes an array of delimiter strings instead of chars. It's "new" to 2.0, but hopefully that won't be an issue for you. Jon haha, he was talking about himself I believe. As in "Duh, why didn't I figure that out"  Signature- Nicholas Paldino [.NET/C# MVP] - mvp@spam.guard.caspershouse.com On Jul 30, 3:55 pm, CSharper <cshar...@gmx.com> wrote: > > Use Regex.Split. > > Duh???

I split the string after a "<td id=\"...\">" element, or something similar, that occurred once and was unique, and took the second part. Then I took the first part of the split at "</td>". Then I took the second part of "<a href=\"". Then I took the first part of ">". On Jul 30, 3:55 pm, CSharper <cshar...@gmx.com> wrote: > > Use Regex.Split. > > Duh???

It has an overload which takes String (not char) delimiters: public string[] Split( string[] separator, StringSplitOptions options ) They may be using .NET 1.1, which doesn't have the string parameter overloads.

Yes; use String.Split. It has an overload which takes String (not char) delimiters: public string[] Split( string[] separator, StringSplitOptions options ) CSharper, Have you taken a look at the RegEx class? Specifically, the Split method on the RegEx class?

You can use the pattern "<td[^>]*>([\w\W]*?)</td>" with the Regex.Match method to find the contents of all td elements in the string. <td[^>]*> matches the starting tag even if it has arguments [^>] matches any character except > * means zero or more matches () catches the value [\w\W] matches any character *? makes a non-gready match, so that it ends at the first </td>, not the last Note: This doesn't work well if you have nested tables.
