无法读取嵌套xml标记的属性（QXmlStreamReader）

Question

我有XML文件（我必须简化它）：

<Line line1_attr1 = "value1" line1_attr2 = "value2">
    <Term line1_term1_attr1 = "term1value1" line1_term1_attr2 = "term1value2">
        term content
    </Term>
    <Term line1_term2_attr1 = "term2value1" line1_term2_attr2 = "term2value2">
        term content
    </Term>
</Line>
<Line line2_attr1 = "value1" line2_attr2 = "value2">
    <Term line2_term1_attr1 = "term1value1" line2_term1_attr2 = "term1value2">
        term content
    </Term>
    <Term line2_term2_attr1 = "term2value1" line2_term2_attr2 = "term2value2">
        term content
    </Term>
</Line>

属性存储在两个QMaps中：mapString（Line的属性）和MapTerm（Term的属性）。 我可以读取Line标记的属性，但不能读取Term标记的属性。 不是这个

if(token == QXmlStreamReader::StartElement)
{
    if (xml.name() == "Line")
    {
        QXmlStreamAttributes attrib = xml.attributes();
        for(auto e : mapString->keys())
        {
              mapString->insert(e, attrib.value(e).toString());
        }
        continue;
        if (xml.name() == "Term")
        {
            QXmlStreamAttributes attrib = xml.attributes();
            for(auto e : mapTerm->keys())
            {
                  mapTerm->insert(e, attrib.value(e).toString());
            }
            continue;
        }                  
    }

也不是

if(token == QXmlStreamReader::StartElement)
{
    if (xml.name() == "Line")
    {
        QXmlStreamAttributes attrib = xml.attributes();
        for(auto e : mapString->keys())
        {
              mapString->insert(e, attrib.value(e).toString());
        }
        continue;       
    }
    if (xml.name() == "Term")
    {
        QXmlStreamAttributes attrib = xml.attributes();
        for(auto e : mapTerm->keys())
        {
              mapTerm->insert(e, attrib.value(e).toString());
        }
        continue;
    } 

正在运行， if（xml.name（）==“Term”）中的代码未执行。
