以下是我的程序代码:*******************************************************
procedure TForm1.Button5Click(Sender: TObject);
var
xmlobj:TDOMDocument40;
xmlsch:TXMLSchemaCache40;
namespace,xsdname,xmlname:string;
begin
namespace:='urn:records';
xsdname:='XLQ.xsd';
xmlname:='XLQ.xml';
xmlobj := TDOMDocument40.Create(nil);
xmlsch := TXMLSchemaCache40.Create(nil);
xmlsch.DefaultInterface.add(namespace,xsdname);
xmlobj.DefaultInterface.schemas := xmlsch.DefaultInterface;
xmlobj.DefaultInterface.async := False;
xmlobj.DefaultInterface.validateOnParse := True;
xmlobj.DefaultInterface.resolveExternals:=True;
xmlobj.DefaultInterface.load(xmlname);
if xmlobj.DefaultInterface.parseError.errorCode = 0 then
showmessage('格式正确')
else begin
showmessage('格式错误');
showmessage(xmlobj.DefaultInterface.parseError.reason
+xmlobj.DefaultInterface.parseError.srcText
+' line:'+IntToStr(xmlobj.DefaultInterface.parseError.line)
+' char:'+IntToStr(xmlobj.DefaultInterface.parseError.linepos));
end;
end;
*******************************************************
我在程序运行后出现以下错误:
“sstzclass”/union/ undeclared XSD type:'noneclass'
*******************************************************
我分析是我定义的xsd文件中的联合类型出现问题,但是我仔细检查我的xsd文件,对照
MSXML4.0的文档,我始终无法找到问题所在.请各位高手多多指点。如果可能的话，给我一个使用了union类型定义的xsd文件的示例。谢谢。
我的xsd的内容是:
