[xsd-users] Elements/attrs not recognized

[Homer J S]

Thank you so much Boris. I hope you wont mind I ask another question please. The input string I parsed 

'<wells xmlns="http://www.witsml.org/schemas/120"
version="1.2.0"><well
uidWell=''><nameWell/><nameLegal/><dTimSpud/><numAPI/><statusWell/><field></field><country/><state/><county/><block/><operator/><location><latitude/><longitude/><inputType/></location><commonData><nameSource/><dTimStamp/><dTimCreation/><dTimLastChange/><itemState/><comments/></commonData></well></wells>'

contains element <statusWell/> which is an enumeration defined below:

    <xsd:simpleType name="WellStatus">
        <xsd:restriction base="xsd:string">
            <xsd:enumeration value="Abandoned"/>
            <xsd:enumeration value="Active"/>
            <xsd:enumeration value="Drilling"/>
            <xsd:enumeration value="DrillingSuspended"/>
            <xsd:enumeration value="Permitted"/>
            <xsd:enumeration value="PartiallyPlugged"/>
            <xsd:enumeration value="PluggedAndAbandoned"/>
            <xsd:enumeration value="Proposed"/>
            <xsd:enumeration value="Plugged"/>
            <xsd:enumeration value="StatusUnknown"/>
            <xsd:enumeration value="Suspended"/>
            <xsd:enumeration value="TemporarilyAbandoned"/>
        </xsd:restriction>
    </xsd:simpleType>

The
problem is that the parser raised an error because the input string
does not explicitly specify a value for element statusWell. Is there a
way to bypassing this problem please.

Thanks
JS

No, not too serious ;-). See Q2.1 in the C++/Tree Mapping FAQ:
