Reading mail attachment, which is excel file with xHTML content

Hello

Mail is sent from Ariba which has ZIP attachment. Inside that zip file is a '.xls' file. But this '.xls' file has xHTML content (i.e content is wrapped around xHTML tags).

Purpose is to read the attachment , convert it in csv /.doc format and send it to R/3.

Till now, PI is able to read mail , unzip the attachment, but not able to convert the .xls file into desired format in PI.

Size of File>50000 records;

Kindly suggest.

Thanks

Pratibha
