i am having trouble finding examples to test something like this...

	 	if ( searchStr.length() < 2 ) {
	 		ApexPages.addMessage( new ApexPages.Message(
	 			ApexPages.Severity.INFO, 'Search requires more characters'));
	 		return null;
	 	}

thank you.

I'm trying to sign an XML document in one of my Apex classes.  Does Apex have any built in classes for signing XML documents?  Ie, like using the javax.xml.crypto.dsig.XMLSignature class or the Apache Santuario library?  I've looked at the Crypto.sign function, but I don't think it does what I need it to do (or if it does, please let me know!).

Thanks for any suggestions!
