python - lxml: Converting XML to HTML through XSLT and get HtmlElements -

I have data that comes in the form of an XML file, I have also been given XSLT to convert XML to HTML I can use LXL to convert, however, I want to replace some HTML tags after conversion. How do I change this new entry into HTML Elements so that I can use some special methods like .cssselect () and so on.

  & gt; & Gt; & Gt; Import lxml.etree & gt; & Gt; & Gt; Import lxml.html & gt; & Gt; & Gt; & Gt; & Gt; & Gt; Xmlstring = '' '\ ... & lt ;? XML version = '1.0' encoding = 'ASCII'? & Gt; ... & lt; Root & gt; & Lt; One class = "here" & gt; Link1 & lt; / A & gt; & Lt; One class = "there" & gt; Link2 & lt; / A & gt; & Lt; / Root & gt; ... '' '& gt; & Gt; & Gt; Root = lxml.etree.fromstring (xmlstring)> gt; & Gt; & Gt; Root.cssselect ('a.here') traceback (last most recent call): File "& lt; stdin>", line 1, & lt; Module & gt; AttributeError: The 'lxml.etree._Element' object has no attribute in the 'cssselect'
