[xpath] 取得 最大最小值 xpath 1.0 min and max td

[xpath] 取得 最大最小值 xpath 1.0 min and max td

由於 chrome 內的 xpath 是使用 libxml2 所以目前是 xpath 1.0
怎麼取得 td list 中的最大最大值呢?

"No, Chrome uses XPath 1.0.
You can simplify your XPath expression to just a v2.0 function to see this:"
Google Chrome (or Chromium) still uses libxml2 thus is limited to XPath 1.0. Cf. this Readme from the source.
