Given an XML file, you want to run several queries for data in the file based on filter criteria the user will be entering for a particular purpose.
Which class would be more appropriate for these queries on the file?

The XmlDocument class is better suited for single-purpose queries because it supports random access to the XML nodes through XPath queries.

The XmlReader class is faster but much more difficult to use when running single-purpose queries, and no query language can be used.
