我可以用Firefox和硒xpath 2.0吗？ [英] Can I use xpath 2.0 with firefox and selenium?

问题描述

我看到其他问题提到xpath 2.0，这显然简化了字符串表达式。我使用Firefox 3.5.5和Selenium 1.0.1。

I saw other questions referring to xpath 2.0, which apparently simplifies string expressions. I'm using Firefox 3.5.5 and selenium 1.0.1.

• 如何检查我的Firefox和Selenium版本是否支持它？


• Selenium是否遵循Firefox的内置Xpath实现？
在这种情况下，如果我开始使用另一个（也许是较老的）selenium浏览器，我会遇到预期xpath 2.0的问题吗？

• How can I check if my versions of Firefox and Selenium support it?
• Does Selenium defer to Firefox's built-in Xpath implementation?
• In that case, if I start using another (perhaps older) browser with selenium, will I run into problems by expecting xpath 2.0?

推荐答案

默认情况下，selenium使用浏览器自带的XPath版本。你可以使用Selenium自带的一个版本，用JavaScript编写。这看起来实现了XPath 1.0，基于对源代码的观察。

By default, selenium uses the "native" version of XPath that comes with the browser. You can make it use a version that comes with Selenium, written in JavaScript. This seems to implement XPath 1.0, based on glancing at the source.
