Hello,
Are there any tools in Matlab that will check that an xml file coforms to a given xml schema (.xsd) file?
Thanks!

As of now, there is no in-built function in MATLAB to validate the given XML file with the XSD given by the user.

You can call Java libraries from MATLAB.
Example pure Java code can be found at stackoverflow.com. Translated to Java calls from MATLAB:
schemaFileName = "MySchema.xsd";
xmlFileName = "MyXML.xml";
schemaFile = java.io.File(schemaFileName);
xmlFile = java.io.File(xmlFileName);
schemaFactory = javax.xml.validation.SchemaFactory.newInstance(javax.xml.XMLConstants.W3C_XML_SCHEMA_NS_URI);
schema = schemaFactory.newSchema(schemaFile);
validator = schema.newValidator();
fileInputStream = java.io.FileInputStream(xmlFile);
streamSource = javax.xml.transform.stream.StreamSource(fileInputStream);
validator.validate(streamSource); % throws an exception if not valid
