My requirement is... i have an xml file. In which i need to set the value for a tag.

Please refer to the xml file .My requirement is , say for the attached xml,

book tag is repeating. First i need to see which book is having the attribute 'id' as bk102. And then i need to find whether the value of title is "Midnight Rain". If its Midnight Rain then i need to update the value of "price" tag to 10. Currently it is 5.95..i need to change this to 10.

Can someone tell me which would be the best approach to do this.

Thanks !!!
