Описание
class 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.
