xmllint with html entities in XPath

Question

I'm trying to use xmllint to parse different values out of an XML.

The tags look like this:

<attribute name="Fel&#xFC;letkezel&#xE9;" value="Painted /Festett/" />

I'm using the following XPath with xmllint and all I get is XPath set is empty:

xmllint --xpath 'string(xml/transactions/transaction/document/configuration/attribute[@name="Felületkezelés"]/@value)'

I'm expecting it to return "Painted /Festett/". I've tried escaping the semicolons.

Using recode or xmlstarlet is not an option.

How can I get the value of the tag with html entities in XPath?
