Calling with xerces

Code generation > Calling a parser > Calling with xerces

If xerces dnodes are used in the project, the code for the call of a parsers must be enlarged. You have to set the options for the xerces DOM manually. Dont't forget to set CTT_ParseStateDomPlugin as plugin in the options for the code generation.
