Using or with strfind

Hello,

I have two patterns p1 (or) p2, to be found within a single string, str. The objective is to get the position if either of those two patterns is found. But the following doesn't seem to work:

position=strfind(str,p1 || p2)

How to modify this statement to get the result?

Thanks.

position1 = strfind(str,p1) ; 
position2 = strfind(str,p2) ; 

OR

position = strfind(str,[p1, p2]) ;

Thanks. But doesn't seem to work.

str='<s 123>item1<m>list unwanted<dfy 97>item2<m>';
p1='<s 123>';
p2='<dfy 97>';
p3='<m>';
startPosition=strfind(str,[p1,p2]);
startPosition=startPosition+numel(p1);
endPosition=strfind(str,p3);
endPosition=endPosition-1;

This gives

startPosition =
     []

Also, how to resolve the fact the lengths of p1 and p2 are different, and hence, there is a mismatch in the startPosition when adding numel(p*) to it?

The objective is to extract out the items: item1 and item2.

position1 = strfind(str,p1) ; 
position2 = strfind(str,p2) ;
