I have searched in forums, tutorials and manual but I couldn´t find anything about xml filtered.
I have found an API calls DOM, but
I give you an example, maybe you can help me:

I have the follow XML code:
<XML>
<ROW Name="Marty" Surname="Crespi"
Email="crespi.marty@gmail.com"/>
<ROW Name="Pepito" Surname="Ape Pepito"
Email="pepito@suemail.com.co"/>
<ROW Name="Pepito" Surname="Ape Pepito2"
Email="pepito2@suemail.com"/>
</XML>
I need something that allows me manipulate this xml:
example
"Search information about an attribute: search from "surname" the string "crespi"
Filter a data from an attribute, for example: returns in an other xml, the rows that match with the conditions in the filter, for example Name="Pepito".

well, and then can insert new rows, modify, and delete them
Thank you very much!
