PHP app that remove child att from input xml files.

I want simple but shell script triggerable php app to remove specific child att from xml files. I have 20 xml files and the syntax looks like this: //[login to view URL] <?xml version="1.0" encoding="UTF-8"?> <strings locale="en_US"> <pkg name="foo"> <string key="friend"> <original>xx</original> </string> <string key="carrotcake_description"> <original>xx</original> </string> <string key="sweetsake_description"> <original>xx</original> </string> <string key="sweetsake_description_plural"> <original>xx</original> </string> <string key="fruitwine_SEX"> <original>You got {count} {itemUnit,object,definite,count}.</original> <variation index="0">{count} {itemUnit,fem,definite,plural}.</variation> <variation index="1">{count} {itemUnit,fem,definite,singular}.</variation> <variation index="2">{count} {itemUnit,masc,definite,plural}.</variation> </string> <string key="fruitwine_description_SEX"> <original>xx</original> </string> <string key="fruitwine_description_plural_SEX"> <original>xx</original> </string> <string key="fruitwine_e"> <original>xx</original> </string> </pkg> </strings> and this php app will remove all the child att that have xxxxxx_SEX key, so final xml will look like this: //[login to view URL] <?xml version="1.0" encoding="UTF-8"?> <strings locale="en_US"> <pkg name="foo"> <string key="friend"> <original>xx</original> </string> <string key="carrotcake_description"> <original>xx</original> </string> <string key="sweetsake_description"> <original>xx</original> </string> <string key="sweetsake_description_plural"> <original>xx</original> </string> <string key="fruitwine_e"> <original>xx</original> </string> </pkg> </strings> Please bid on this, I am sure this is kinda basic to php programmer. Let me know. ;-)
