DOMDocument->getElementById()
DOMDocument->getElementById() -- Searches for an element with a certain id
Описаниеclass DOMDocument { DOMElement getElementById ( string elementId ) } This function is similar to
DOMDocument->getElementsByTagName() but
searches for an element with a given id.
According to the DOM standard this requires a DTD which defines the
attribute ID to be of type ID. You need to validate your document with
DOMDocument->validate()
or DOMDocument->validateOnParse before using this function.
