<p>ESQuery is a library for querying the AST output by Esprima for
patterns of syntax using a CSS style selector system. Check out the
demo:</p>
<p><a href="https://estools.github.io/esquery/">demo</a></p>
<p>The following selectors are supported:</p>
<ul>
<li>AST node type: <code>ForStatement</code></li>
<li><a
href="http://dev.w3.org/csswg/selectors4/#universal-selector">wildcard</a>:
<code>*</code></li>
<li><a
href="http://dev.w3.org/csswg/selectors4/#attribute-selectors">attribute
existence</a>: <code>[attr]</code></li>
<li><a
href="http://dev.w3.org/csswg/selectors4/#attribute-selectors">attribute
value</a>: <code>[attr="foo"]</code> or <code>[attr=123]</code></li>
<li>attribute regex: <code>[attr=/foo.*/]</code> or (with flags)
<code>[attr=/foo.*/is]</code></li>
<li>attribute conditions: <code>[attr!="foo"]</code>,
<code>[attr&gt;2]</code>, <code>[attr&lt;3]</code>,
<code>[attr&gt;=2]</code>, or <code>[attr&lt;=3]</code></li>
<li>nested attribute: <code>[attr.level2="foo"]</code></li>
<li>field: <code>FunctionDeclaration &gt; Identifier.id</code></li>
<li><a
href="http://dev.w3.org/csswg/selectors4/#the-first-child-pseudo">First</a>
or <a
href="http://dev.w3.org/csswg/selectors4/#the-last-child-pseudo">last</a>
child: <code>:first-child</code> or <code>:last-child</code></li>
<li><a
href="http://dev.w3.org/csswg/selectors4/#the-nth-child-pseudo">nth-child</a>
(no ax+b support): <code>:nth-child(2)</code></li>
<li><a
href="http://dev.w3.org/csswg/selectors4/#the-nth-last-child-pseudo">nth-last-child</a>
(no ax+b support): <code>:nth-last-child(1)</code></li>
<li><a
href="http://dev.w3.org/csswg/selectors4/#descendant-combinators">descendant</a>:
<code>ancestor descendant</code></li>
<li><a

<code>parent &gt; child</code></li>
<li><a
href="http://dev.w3.org/csswg/selectors4/#general-sibling-combinators">following
sibling</a>: <code>node ~ sibling</code></li>
<li><a

<code>:matches([attr] &gt; :first-child, :last-child)</code></li>
<li><a href="http://dev.w3.org/csswg/selectors4/#subject">subject
indicator</a>: <code>!IfStatement &gt; [name="foo"]</code></li>
<li>class of AST node: <code>:statement</code>,
