How to split a string twice

I am trying to split a string twice

XML

String example = response;
        String [] array = example.split("<section>");
        System.out.println(array[0]);

        String [] array2 = example.split("<title>");
        System.out.println(array2[2]);

I was trying to achieve this by using this code (not successfully), but instead of printing the first split I would like to save it and carry on with the 2nd split.
Would anyone have a solution to this problem or better way of going about splitting a string twice?

I don't understand what it is you are trying to achieve.

Could you post what the string reponse might contain and what you expect to be returned in your first and second println commands.
Thanks

It depends on what you wanted to achieve. I can understand why this way may complicate things. How about splitting my one set of delimiters, and then splitting the result of first split? Or split by a complex Regex..?

 String [] array2 = example.split("<title>");
 System.out.println(array2[2])

If i understand you well, you're trying to split some text into parts based on different condition. Firtly, you want to devide text on "<section>" then (secondly) on "<title>" statement.
Now, have a look at mine pseudo-code (i'm not familiar with java enough):

Java

String [] array = example.split("<section>");
System.out.println(array[0]);
//for each part in a first array
for(int i=0,array[].UBound(),i++)
{
    String [] array2 = array[i].split("<title>");
}

Do you see the difference?

Isn't that exactly the same I advised in my comment to the question and hour ago?

You're right. I think, we can treat this answer as a support to your last comment ;)

Please see my comment to the question where I advice to split in some different ways. But it looks like your source string is XML, so, in most cases, you should rather use an XML parser and parse all you have at once. You can use javax.xml.xpath:
http://docs.oracle.com/javase/7/docs/api/javax/xml/xpath/package-summary.html[^].

For complete documentation on XML parsing, please see: http://docs.oracle.com/cd/B28359_01/appdev.111/b28394/adx_j_parser.htm[^].

Good luck, best wishes in New Year!
