错误: lxml.etree.XMLSyntaxError:预期Error= '>‘>

Question

我把这个XML数据放在一个字符串中：

<?xml version="1.0" encoding="UTF-8"?>
<class name="C" kind ="concrete">
    <inheritance>
        <from name="A" privacy="public" />
        <from name="B" privacy="public" />
    </inheritance>
    <private>
        <methods>
            <method name="C" type="C" scope="instance">
                <arguments></arguments>
        </methods>
    </private>
</class>

我想找到一些使用xpath的元素。到目前为止，这是我的代码：

utf8_parser = etree.XMLParser(encoding='utf-8')
root = etree.fromstring(string.encode('utf-8'), parser=utf8_parser)
somelist = root.findall(xpathString)

我发现了一个错误：

root = etree.fromstring(stringOutput.string.encode('utf-8'), parser=utf8_parser)

lxml.etree.XMLSyntaxError: expected '>', line 11, column 11

我想问题可能是字符串中的双引号。有可能吗？使用xpath查找元素的适当代码应该是什么样的呢？

分隔属性值的双引号是完全正确的，但是缺少结束标记的method元素不是。下面是为格式良好而修复的XML：

<?xml version="1.0" encoding="UTF-8"?>
<class name="C" kind ="concrete">
    <inheritance>
        <from name="A" privacy="public" />
        <from name="B" privacy="public" />
    </inheritance>
    <private>
        <methods>
            <method name="C" type="C" scope="instance">
                <arguments></arguments>
            </method>
        </methods>
    </private>
</class>
