Getting Started: 5. CSS Queries

XPath is very powerful but CSS Selectors are more concise sometimes.

Concise syntax

$eggs   = $food('egg');
$fruits = $food('fruit[price="expensive"');

Extended syntax

$eggs   = $food->query('egg');
$fruits = $food->query('fruit[price="expensive"]');

Pro Tip:
Like for XPath, query() supports a variable number of CSS queries. In addition, XPaths and CSS Selectors can be mixed in the same query.

$food('//title', 'chapters > chapter');

The supported CSS selectors are:

• #id
• .class
• E[attr="val"]
• *
• :root
• namespace|E
• E E
• E > E
• E + E
• E ~ E
• E , E

Note:
Remember that CSS selectors are translated internally to XPath and this operation adds some overhead. If you need the best performances possible, go with XPath.
