Hello,
    I met a problem when I using XSDe parsing following xml document:
    <subnet id="98345D87DC77AECB98DF362977"> 
     <sector id=""/> 
     <sector id="A34131"/> 
    </subnet>  
    The schema is defined as:
    <xs:complexType name="subnetType">
     <xs:sequence>
      <xs:element name="sector" type="mi:sectorType" minOccurs="0" maxOccurs="64"/>
     </xs:sequence>
     <xs:attribute name="id" type="mi:hexBin104Type" use="required"/>
    </xs:complexType>
 
    <xs:complexType name="sectorType">
      <xs:attribute name="id" type="mi:hexBin24Type" use="required"/>
    </xs:complexType>
 
    <xs:simpleType name="hexBin104Type">
     <xs:restriction base="xs:hexBinary">
      <xs:length value="13" fixed="true"/>
     </xs:restriction>
    </xs:simpleType>
 
    <xs:simpleType name="hexBin24Type">
     <xs:restriction base="xs:hexBinary">
      <xs:length value="3" fixed="true"/>
    </xs:restriction>
   </xs:simpleType>
 
    The issue is that, when sector id is NULL, std::exception was threw out instead of xml::exception I supposed. I can't get any useful infomation from this exception. Seems the XSDe will not check the length of hexBinary I defined in the schema which could be checked in my own code when setting values, my question is how can I check if the hexBinary is NULL before std::exception was threw out?
    Thanks so much!
                                                                                   Lei, Qiu

Hi,

You can check the buffer's size. For example:

void hexBin104Type_pimpl::
post_hexBin104Type ()
{
  ::xml_schema::buffer* v = post_hex_binary ();

  if (v->size () == 0)
  {
    // empty buffer
  }
  else
  {
    ...
  }

  delete v;
}
