#include <libxml/parser.h>

int main(int argc, char** argv)
{
    xmlDtdPtr xmiDTD;
    xmlChar const * path;

    if (argc !=2)
    {
        printf("syntax: %s <dtdfile>\n", argv[0]);
        return 1;
    }

    path  = (xmlChar const *)argv[1];
    xmiDTD = xmlParseDTD(0, ((char const *)path));
    if(0==xmiDTD) {
        printf("error: xmiDTD=0\n");  
        return 1;
    }
    else
    {
        printf("valid\n");
    }
    return 0;
}

运行时用dtd文件名作参数，出现很多错误，前两个如下：
DTDs/UML-1.4.dtd:188: namespace error : colon are forbidden from entities names 'UML:AggregationKind'
<!ENTITY % UML:AggregationKind '(none|aggregate|composite)'>
                              ^
DTDs/UML-1.4.dtd:189: namespace error : colon are forbidden from entities names 'UML:CallConcurrencyKind'
<!ENTITY % UML:CallConcurrencyKind '(sequential|guarded|concurrent)'>

DTD 文件中出错的片段如下：

<!ELEMENT XMI.reference ANY>
<!ATTLIST XMI.reference %XMI.link.att;>

<!ATTLIST XMI xmlns:UML CDATA #IMPLIED>

<!-- ========= UML:Data_Types ========= -->
<!ENTITY % UML:AggregationKind '(none|aggregate|composite)'>                           这是188行
<!ENTITY % UML:CallConcurrencyKind '(sequential|guarded|concurrent)'>               这是189行

难道是最后两行不能有冒号?规范过时了与解析器不匹配？不明白

请高手帮我看看怎么回事，谢谢！

我还不能上传文件，dtd文件的位置在： http://www.omg.org/spec/UML/20010967/01-02-16.dtd
