<p>

In the call graph viewer below, each node
|
|
is a function belonging to this package
|
|
and its children are the functions it
|
|
calls—perhaps dynamically.
|
|
</p>
|
|
<p>
|
|
The root nodes are the entry points of the
|
|
package: functions that may be called from
|
|
outside the package.
|
|
There may be non-exported or anonymous
|
|
functions among them if they are called
|
|
dynamically from another package.
|
|
</p>
|
|
<p>
|
|
Click a node to visit that function's source code.
|
|
From there you can visit its callers by
|
|
clicking its declaring <code>func</code>
|
|
token.
|
|
</p>
|
|
<p>
|
|
Functions may be omitted if they were
|
|
determined to be unreachable in the
|
|
particular programs or tests that were
|
|
analyzed.

<h2 id="Selector">type <a href="http://localhost:6060/src/github.com/andybalholm/cascadia/selector.go?s=219:254#L5">Selector</a></h2>
|
|
<pre>type Selector func(*<a href="../../../golang.org/x/net/html/index.html">html</a>.<a href="../../../golang.org/x/net/html/index.html#Node">Node</a>) <a href="../../../builtin/index.html#bool">bool</a></pre>
|
|
<p>
|
|
A Selector is a function which tells whether a node matches or not.
|
|
</p>
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|

<h3 id="Compile">func <a href="http://localhost:6060/src/github.com/andybalholm/cascadia/selector.go?s=1022:1064#L31">Compile</a></h3>
|
|
<pre>func Compile(sel <a href="../../../builtin/index.html#string">string</a>) (<a href="index.html#Selector">Selector</a>, <a href="../../../builtin/index.html#error">error</a>)</pre>
|
|
<p>
|
|
Compile parses a selector and returns, if successful, a Selector object
|
|
that can be used to match against html.Node objects.
|
|
</p>
|
|
|
|
|
|
|
|
|
|
|
|
<h3 id="MustCompile">func <a href="http://localhost:6060/src/github.com/andybalholm/cascadia/selector.go?s=1371:1408#L46">MustCompile</a></h3>
|
|
<pre>func MustCompile(sel <a href="../../../builtin/index.html#string">string</a>) <a href="index.html#Selector">Selector</a></pre>
|
|
<p>
|
|
MustCompile is like Compile, but panics instead of returning an error.
|
|
</p>
|
|
|
|
|
|
|
|
|
|
|
|
|
|

<h3 id="Selector.Filter">func (Selector) <a href="http://localhost:6060/src/github.com/andybalholm/cascadia/selector.go?s=2415:2481#L93">Filter</a></h3>
|
|
<pre>func (s <a href="index.html#Selector">Selector</a>) Filter(nodes []*<a href="../../../golang.org/x/net/html/index.html">html</a>.<a href="../../../golang.org/x/net/html/index.html#Node">Node</a>) (result []*<a href="../../../golang.org/x/net/html/index.html">html</a>.<a href="../../../golang.org/x/net/html/index.html#Node">Node</a>)</pre>
|
|
<p>
|
|
Filter returns the nodes in nodes that match the selector.
|
|
</p>
|
|
|
|
|
|
|
|
|
|
|
|
|
|
<h3 id="Selector.Match">func (Selector) <a href="http://localhost:6060/src/github.com/andybalholm/cascadia/selector.go?s=1999:2041#L73">Match</a></h3>
|
|
<pre>func (s <a href="index.html#Selector">Selector</a>) Match(n *<a href="../../../golang.org/x/net/html/index.html">html</a>.<a href="../../../golang.org/x/net/html/index.html#Node">Node</a>) <a href="../../../builtin/index.html#bool">bool</a></pre>
|
|
<p>
|
|
Match returns true if the node matches the selector.
|
|
</p>
|
|
|
|
|
|
|
|
|
|
|
|
|
|
<h3 id="Selector.MatchAll">func (Selector) <a href="http://localhost:6060/src/github.com/andybalholm/cascadia/selector.go?s=1589:1642#L56">MatchAll</a></h3>
|
|
<pre>func (s <a href="index.html#Selector">Selector</a>) MatchAll(n *<a href="../../../golang.org/x/net/html/index.html">html</a>.<a href="../../../golang.org/x/net/html/index.html#Node">Node</a>) []*<a href="../../../golang.org/x/net/html/index.html">html</a>.<a href="../../../golang.org/x/net/html/index.html#Node">Node</a></pre>
|
|
<p>
|
|
MatchAll returns a slice of the nodes that match the selector,
|
|
from n and its children.
|
|
</p>
|
|
|
|
|
|
|
|

|

<h3 id="Selector.MatchFirst">func (Selector) <a href="http://localhost:6060/src/github.com/andybalholm/cascadia/selector.go?s=2138:2191#L78">MatchFirst</a></h3>

<pre>func (s <a href="index.html#Selector">Selector</a>) MatchFirst(n *<a href="../../../golang.org/x/net/html/index.html">html</a>.<a href="../../../golang.org/x/net/html/index.html#Node">Node</a>) *<a href="../../../golang.org/x/net/html/index.html">html</a>.<a href="../../../golang.org/x/net/html/index.html#Node">Node</a></pre>
|

<p>

MatchFirst returns the first node that matches s, from n and its children.
