{{Short description|Content-based retrieval of XML documents}}

'''XML retrieval''', or '''XML information retrieval''', is the content-based retrieval of documents structured with [[XML]] (eXtensible Markup Language). As such it is used for computing [[Relevance (information retrieval)|relevance]] of XML documents.<ref>{{Cite web |last=PalLalmas |first=SukomalMounia |date=June 30, 20062009 |title="XML Retrieval |url=https: A Survey"//fi.wikipedia.org/wiki/XML-tiedonhaku#L%C3%A4hteet |urlpublisher=CiteSeerXMorgan 10.1.1.109.5986& Claypool}}</ref>

Therefore, they need to be extended to allow for vague search with relevance computing. Most XML-centered approaches imply a quite exact knowledge of the documents' [[Database schema|schemas]].<ref name="Schlieder2002">{{Cite journal|url=http://www.cis.uni-muenchen.de/people/Meuss/Pub/JASIS02.ps.gz |title=Querying and Ranking XML Documents |last=Schlieder |first=Torsten |author2=Meuss, Holger |year=2002 |journal=Journal of the American Society for Information Science and Technology |volume=53 |issue=6 |pages=489–503 |access-date=2009-02-10 |archive-url=https://web.archive.org/web/20070610002349/http://www.cis.uni-muenchen.de/people/Meuss/Pub/JASIS02.ps.gz |archive-date=June 10, 2007 |doi=10.1002/asi.10060 |url-access=subscription }}</ref>
