Re: Split string

Lainaus Ricardo Saraiva <rss@xxxxxxxxxxxxxx>:

< Hello,
< 
< 	How do I split a string into several strings by a given token?
< 
< 	The example that follows shows what is supposed to be done:
< 
< The input:
< 
< <ToName>person1;person2</ToName>
< <ToAddress>mail1;mail2</ToAddress>
< 
< Desired output:
< 
< <To>
<   <Contact>
< 	<Name>person1</Name>
<       <Address>mail1</Address>
<   </Contact>
<   <Contact>
< 	<Name>person2</Name>
<       <Address>mail2</Address>
<   </Contact>
< </To>
< 
< Thanks in advance,
< 
< Ricardo Saraiva.
