使用sabberworm / PHP-CSS-Parser解析css文件 [英] parsing a css file with sabberworm/PHP-CSS-Parser
问题描述
我使用这个类来解析.css文件。
https://github.com/sabberworm/PHP-CSS-Parser
我认为这很容易,但这个类很复杂,我完全绿色的面向对象编程,所以我有一个问题。
I use this class to parse a .css file. https://github.com/sabberworm/PHP-CSS-Parser I thought it's easy but this class is complicated and I'm completly green in object oriented programing, so I have a problem.
(...)包括所有类文件等。
(...) including all class files etc.
$oParser = new CSSParser(file_get_contents('files/sample.css'));
$oDoc = $oParser->parse();
$selectors=$oDoc->getAllRuleSets();
$nazwy=$oDoc->getContents();
foreach($selectors as $selektor=> $val)
{
$w=$val->getSelectors();
echo "<h3>$selektor</h3>";
$tmp=$val->getRules();
foreach($tmp as $nazwa => $attrib)
{
$wartosc= $attrib->getValue();
echo "<br>$nazwa:$wartosc;";
}
}
此代码将输出如下
<h1>0</h1>
color:red;
margin:10px;
<h1>1</h1>
color:green;
margin:20px;
这几乎确定,但我想要选择器名称(例如div #someid),而不是当前css块的索引。
it's almost ok but I want selectors names (eg div #someid) instead of index of current css block.Have any idea how to get those?
推荐答案
使用 echo< h3>implode (','$ w)。< / h3>
。
原因如下: $ val
表示一个声明块,它是一个具有多个逗号分隔的选择器的规则集(键 $ selektor
只包含声明块的索引这对于大多数使用是完全任意的)。要获得选择器,使用 $ val-> gtSelectors()
(你做的)。这将为您提供所有选择器的数组。
The reason is as follows: $val
represents a declaration block which is a rule set with several comma-separated selectors (The key $selektor
only contains the index of the declaration block which is completely arbitrary for most usages). To get the selectors, use $val->getSelectors()
(which you did). This will get you an array of all selectors.
声明块:
h1, h2 { value: 1; }
将被解析为 CSSDeclarationBlock
对象与选择器数组['h1','h2']。要返回最初定义的选择器,请使用 implode
。
will thus be parsed into a CSSDeclarationBlock
object with the selector array ['h1', 'h2']. To get back the selectors as they were originally defined, use implode
.
