etree xpath处理中文乱码问题解决

不知道为啥突然碰到一个页面etree xpath获取到的中文是乱码。最后靠加HTMLParser参数搞定。代码如下

    @staticmethod
    def getXpath(xpath, content):  
        hparser = etree.HTMLParser(encoding='utf-8')

        tree = etree.HTML(content,hparser)
        out = []
        results = tree.xpath(xpath)
        for result in results:
            if  'ElementStringResult' in str(type(result)) or 'ElementUnicodeResult' in str(type(result)) :
                out.append(result)
            else:
                out.append(etree.tostring(result))
        return out
