XPath queries in Google Chrome console
Evaluating $x returns ...
function $x(xpath, [startNode]) { [Command Line API] }So, the syntax is $x('my/path', a).
Important is that, $x returns an array but startNoderequires a DOM node, so you have to take an element of the first query. The following sample demonstrates the behavior on the current page.
a = $x("//*[@id='question-header']")> [ <div id="question-header">…</div> ]b = $x(".//*[@href]/text()", a[0])> [ "XPath queries in Google Chrome console" ]Update: Here is the documentation.
