The DefaultElementName Data Member
Each class generated by HydraExpress has a data member called DefaultElementName. This data member is an instance of rwsf::XmlName.
The DefaultElementName for a class is determined as follows:
For top-level elements, the DefaultElementName is the element name.If the top-level element name would result in a file that conflicts with another file name in the default namespace, HydraExpress renames it elementnameElement.
For named complex types, the DefaultElementName is the complex type name.For anonymous complex types, the DefaultElementName is the name of the containing element.The marshal() and unmarshal() methods for a class use the DefaultElementName by default. This allows you to simply call marshal() or unmarshal() on a class, usually with good results. For example, if the schema defines a top-level element named purchaseOrder, the following code usually works as expected:
PurchaseOrder po;
po.marshal();
This code should produce, as expected, an XML document with a top-level element <purchaseOrder>.
There is one case, however, where the default use of the DefaultElementName does not work as you might expect:
<element name="foo" type="bar"/>
<complexType name="bar">
...
</complexType>
In this case, if the following code were used:
Bar b;
b.marshal();
the result would be an XML document containing a top-level element called <bar>, when it would make better sense for the name of the element to be <foo>. To obtain this better result, the second line above would need to be:
b.marshal("foo","schema_target_namespace");
