I have an xml file and i am parsing the file. Before parsing i have a field by name action it can have ADD or Delte. The XSD is defined for this also. But there is another field FEEDTYPE this can be FULL or DELTA. The requirement is as below If feedtype == full then action should be only ADD. and feedtype==delta then action can be both. I want to achive the above one. Is it possible to specify this in the XSD? If not I want to validate the above rule before parsing since i dont want to parse the file and at the last record find that it is invalid. Please help me in this............. Please use html tags to format code blocks.    More>>
