错误：lxml.etree.XMLSyntaxError：预期为'>'

我在字符串中有此XML数据：

<?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)

我收到此错误：

root = etree.fromstring(stringOutput.string.encode('utf-8'), parser=utf8_parser)
  File "lxml.etree.pyx", line 3032, in lxml.etree.fromstring (src/lxml/lxml.etree.c:68106)
  File "parser.pxi", line 1785, in lxml.etree._parseMemoryDocument (src/lxml/lxml.etree.c:102455)
  File "parser.pxi", line 1673, in lxml.etree._parseDoc (src/lxml/lxml.etree.c:101284)
  File "parser.pxi", line 1074, in lxml.etree._BaseParser._parseDoc (src/lxml/lxml.etree.c:96466)
  File "parser.pxi", line 582, in lxml.etree._ParserContext._handleParseResultDoc (src/lxml/lxml.etree.c:91275)
  File "parser.pxi", line 683, in lxml.etree._handleParseResult (src/lxml/lxml.etree.c:92461)
  File "parser.pxi", line 622, in lxml.etree._raiseParseError (src/lxml/lxml.etree.c:91757)
lxml.etree.XMLSyntaxError: expected '>', line 11, column 11

我认为问题可能出在字符串中的双引号上。是否可以？使用xpath查找元素的正确代码应该是什么样的？

限定属性值的双引号是完全可以的，但是method缺少end标记的元素则不是。这是将您的XML修改为格式正确的文件：

<?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>
