Added support for XPath 1.0

[btd]

From test you can see usage.

No one working on xpath support?

The performance of CSS locator (selector) is significantly faster than Xpath.
It would also be easy to rewrite Xpath into CSS locator scripts. :)

For your reference:

In my test with HTMLUnit (using XPath) and Jsoup (using CSS locator), the result also shows the same!

[Testing Log]

Parsing E:/profiling.html using Xpath ...
Loading doc by HTMLUnit ...
Time spent: 8122.613623 milliseconds.

Searching doc by HTMLUnit ...
XPath: //div[@Class="alonesort"]/div[@Class="mc"]/dl[@Class="fore"]/dd/em/span/a
Matched Element Count: 1260
Time spent: 35.006174 milliseconds.

Parsing E:/profiling.html using CSS Selector ...
Loading doc by Jsoup ...
Time spent: 151.277634 milliseconds.

Searching doc by Jsoup ...
CSS Locator: div.alonesort > div.mc > dl.fore > dd > em > span > a
Matched Element Count: 1260
Time spent: 13.975146 milliseconds.

I think Jsoup is already good enough by supporting CSS locator!
The rule is also shorter and simpler in contrast to Xpath.

Thanks. My requirement is simple. Getting xpath or css selector in browser,
past it in code, get the content. Now using chrome, I can get xpath in dev
tools window easily.
When I try to translate the xpath to css selector, one problem is I don't
know how to handle tag[1], which mean the first tag with name 'tag'. :eq()
means the nth child.

Hi riczhao,

The equivalent expression of "tag[1]" in CSS Selector is "tag:nth-child(1)".
You can check the following links:

Hello,

Please document that JSoup does not currently support XPath, as it is not really clear while it should be at first glance.

I can get cssSelector using jSoup but am not able to get xpath:idrelative, xpath:attributes, xpath:location.
Though I am able to get xpath fixed with the code below:

StringBuilder absPath=new StringBuilder();
Elements parents = e.parents();

                for (int j = parents.size()-1; j >= 0; j--) {
                    Element element = parents.get(j);
                    absPath.append("/");
                    absPath.append(element.tagName());
                    absPath.append("[");
                    absPath.append(element.siblingIndex());
                    absPath.append("]");
                }

Help would be appreciated :)
