Apply multiple conditions to filter data in Data View web part

I was wondering if there is a way to filter the data present in data view web part by applying multiple conditions like this

If((@ApprovalStatus = 'Approved') and (@LOB = $Param1 or $Param1 = 'All'))

After thinking for sometime, I got an idea to add XSLT filtering instead of applying filter criteria available.



So I have checked the checkbox “Add XSLT filtering”, clicked on edit and added the following XSLT like this:

[(@ApprovalStatus = 'Approved') and (@LOB = $Param1 or $Param1 = 'All')]
