[xsd-users] Parsing issue

[Ildar Farkhshatov]

Here is the schema:

 <xs:complexType name="Product">
    <xs:sequence>
      <xs:element name="Name" type="xs:string" />
    </xs:sequence>
  </xs:complexType>
<xs:complexType name="FxEuroOpt">
    <xs:complexContent mixed="false">
      <xs:extension base="Product">
        <xs:sequence>
          <xs:element name="Strike" type="xs:double" />
          <xs:element name="ExpiryDate" type="xs:dateTime" />
          <xs:element name="NotionalAmount" type="xs:double" />
          <xs:element name="NotionalCurrency" type="Currency" />
          <xs:element name="ZoneCut" type="Cut" />
          <xs:element name="CurrencyPair" type="CurrencyPair" />
          <xs:element name="SettleDate" type="xs:dateTime" />
        </xs:sequence>
      </xs:extension>
    </xs:complexContent>
  </xs:complexType>

I am using default C++\Tree parser and turned off the validation.

I looked into parsing code:

this->::Product::parse (p, f);

  for (; p.more_elements (); p.next_element ())
  {
/// fields

//    when field is successfully parsed, the block calls continue;
//    otherwise it hits break; below meaning that after it reaches 
EffectiveDate xml entry with no appropriate class-field for it - it stops 
the parsing

      break;
  }


Best Regards, Ildar.

When XML Schema validation is involved, it is hard to say whether
a particular element can be ignored or not without seeing the
corresponding schema fragment.

There are also ways to disable XML Schema validation but that
depends on which mapping you are using (C++/Tree or C++/Parser).
If you can let me know which mapping it is, I can give you some
pointers on how to turn validation off.
