I need to iterate over the characters in a string to build an XML structure.

Currently, I am doing this :

If the string length is not huge, you can use a recursively called template to achieve this, passing the index of the character to be processed as parameter into the template.

Like so:

    Some text
    
    
        
            
        
        
            
            
        
    

If the string is longer than that, you can use a similar approach but with a divide-and-conquer algorithm, so that you have a maximum recursion depth of log2(string-length), like so:

    Some text
