Re: Validate XML against xsdschema when parsing

[Kjell Ahlstedt <kjell ahlstedt bredband net>]

Schema validation is not integrated with the DOM parser the way DTD validation is. Like Pablo says, you must create both a parser object and a validator object. If you use libxml++ 2.38.0 or later, use XsdValidator. SchemaValidator is deprecated. There is an example in libxml++: https://git.gnome.org/browse/libxml++/tree/examples/schemavalidation

first You have to have an schema.xsd file.

then I think you have to do something like this:

                string schema = "schema.xsd"

SchemaValidator validator(schema);

DomParser parser;

parser.set_throw_messages(true);

               string xml = "file.xml"

parser.parse_file(xml);

validator.validate(parser.get_document());

                xmlpp::Node* rootNode = parser.get_document()->get_root_node();

                ....

and continue parsing.

I haven't test it

Hello all,

 

We have a project that wants to use libxml++ to parse and validate xml files. Originally we use DTD to validate, but recently we want to switch to XML Schema.

However, I cannot find a way to do validation with parsing just as we did with DTD by calling set_validate().

Is there someone who knows if it is possible to do it simply, or I have to create a XsdValidator object separately to validate the XML file?

 

Best regards,

Lingxiao
