Does this support xpath selectors ? about visdom HOT 4 OPEN

@mdrokz sorry for the late reply, this crate does not support xpath selectors. If this requirement is common, I plan to take the time to add this feature recently.

from visdom.

@mdrokz I have added a new feature branch to support xpath selectors. The query methods in this crate used to only accept the type &str as a selector parameter, so i add a new trait TryIntoSelector to allowed more types that implement the trait as a selector too. However, the whole logic of query methods is based on css selectors, it is not easy to add the processing logic of xpath selector. I think a simple but not so efficient way is to convert the xpath selectors into the corresponding css selectors, a small number of xpath selectors may not have corresponding css selectors, this may require expanding the capabilities of css selectors. It will takes a lot of work to fully support xpath selectors, if you have a better solution, we can discuss it here.

Thank you very much for your willingness to contribute code to this crate. You can fork the repo, and checkout a new branch from the feature branch, add code to support xpath selectors and also some unit tests code, then make a PR.

I'm worried that it may take up a lot of your time to implement this feature. If you don't have much time on this, you can also tell me, i can do some of the work together. Thanks again!

Hey @fefit thank you for taking your time to work on this feature, i will fork the project and checkout the branch when i get some time im currently working a full time job so i will be doing this on my spare time i will let you know if i encounter any issues or need your help once i see the branch.
