I tried all that and you can see it on this thread, there are some limitations on indexs on xpath work

I have a text column in a table. We store XML in this column. Now I want to

This works fine but it also works for any tag as long as the name 'Citi
Bank' is present.

How do I have to setup my search in order for this to work so I get an exact
match for the tag and value ?

Would you not be better off with an XML data-type if that's how you want to treat the data?
