plugin shortcode and wordpress shortcode clash

Hello everyone,

I have a custom wordpress plugin in which im filtering out data given between custom short code tags.In my plugin im calling a function which i have added to the add_filter(‘the_content’,’myfunction’) clause which searches the content for my shortcodes and extracts the contents given between them and processses them.

But the problem is whenever i give a wordpress defined shortcode like gallery etc. within my custom short codes specific to my plugin, then all the shortcodes are displayed on the page without no functionality carried out.

This creates a great havoc in my plugin functionality. could someone suggest something to get this fixed. Any help is greatly appreciated.

Thanks,
