cyberseo php script help: if custom field or xml tag is 'this' add to 'this' category? | CyberSEO Pro | Support Forum

hi, i'm trying to see if someone could help me or point me in the right direction to add a php script variable for posts retrieved from cyberseo pro plugin. im working on a group site for a non-profit to combine rss feeds from multiple shelters into one page. their feeds are each bulk with all animals included without a way to filter them into categories in wordpress. is there a way to add rule in the PHP code field where if a certain value is in a custom field or xml tag it will insert the post into a certain category in wordress? so if 'AnimalType' = Dog the imported post will insert into 'Dog' category? i can run taxonomy queries to get posts with that custom field value but trying to find a way to have these inserted into categories for compatibility for other plugin. the feeds contain dogs, cats, bunnies, etc and there isnt a way to filter the rss url to just retrieve dogs or cats from the url structure. any help would be greatly appreciated, thanks!
