lxml.etree.XMLSyntaxError: Start tag expected, '<' not found, line 1, column 1

This error message is indicating that the parser was expecting to find the beginning of an XML tag, but instead found some other character at the very beginning of the input.

This can happen if the input is not actually valid XML, or if there is some corruption or encoding issue causing the parser to interpret the input incorrectly.

To resolve the issue, you may need to review the input and ensure that it is valid XML, or track down any issues with the encoding or formatting of the input.

这个错误是由于在解析HTML文件时发生了标记不匹配的错误。根据错误信息，看起来是在第8行的meta标签和head标签不匹配导致的。在HTML中，每个标签都应该有一个开头标签和一个结束标签，并且这些标签应该按正确的嵌套顺序出现。

要解决这个问题，你可以检查一下HTML文件中的这两个标签的嵌套关系是否正确。确保每个开头标签都有对应的结束标签，并且它们的嵌套顺序是正确的。你可以打开test.html文件，检查第6行和第8行的标签是否正确闭合，或者查看是否有其他标签嵌套错误的情况。

另外，你也可以尝试使用其他的HTML解析库，比如BeautifulSoup，它对于处理HTML标记不匹配的情况有更好的容错能力。使用BeautifulSoup可以帮助你更轻松地解析HTML文件，并且提供了一些便捷的方法来处理标签嵌套问题。

您遇到的问题是XPath表达式中存在无效的断言（predicate），导致XPath解析错误。断言是XPath表达式中用于筛选节点的条件语句，应当符合XPath语法规则。

根据您提供的代码片段，我发现您的XPath表达式存在一些问题。首先，您的XPath表达式应该使用双引号或单引号将字符串括起来，而不是使用空格。其次，您的XPath表达式中缺少右括号。

请尝试使用如下的修正后的XPath表达式：

tel = xmsg.xpath('//ul[@class="1-txt none"]/li')

这个表达式将选择所有class属性为"1-txt none"的ul标签下的li标签。

如果问题仍然存在，请提供更多关于您的代码和XML结构的信息，以便我可以更好地帮助您解决问题。
