[Script]
Implementation Syntax
var bolValid = oISchemaType.isValid(strData);
Parameters
- strData
- A string. The data to be validated.
Return Values
- bolValid
- A Boolean value. The result of validation of the passed-in data.
[Visual Basic]
Implementation Syntax
bolValid = oISchemaType.isValid(strData)
Parameters
- strData
- A string. The data to be validated.
Return Values
- bolValid
- A Boolean value. The result of validation of the passed-in data.
[C/C++]
Implementation Syntax
HRESULT isValid(BSTR data, VARIANT_BOOL* valid);
Parameters
- data [in]
- A string. The data to be validated.
- valid [out,retval]
- A Boolean value. The result of validation of the passed-in data.
Return Values
- S_OK
- The value returned if successful.
- S_INVALIDARG
- The value returned if the data string is NULL.
- S_POINTER
- The value returned if the
Validreturn value is NULL. - S_NOTIMPL

Remarks
Documents containing Qname or NOTATION types or types derived from them cannot be validated currently with XSD. Therefore, validation will fail with E_FAIL and the valid parameter will be returned as VARIANT_TRUE and isValid will return S_FALSE.
