Description

Use an object of the matlab.io.xml.dom.Parser class to convert XML markup to a matlab.io.xml.dom.Document object. A Parser object has two methods for converting XML If the XML is in a file, use the parseFile method to convert the XML markup. If the XML is in character vector or string scalar, use the parseString method.

The XML markup to be parsed must contain only one top-level element, which can be preceded or followed by a comment or processing instruction. If the markup contains more than one top-level element, the parser throws an error after processing the first element. The parser reports comment or processing instruction expected as the reason for the error.

The matlab.io.xml.dom.Parser class is a handle class.
