属性

actualEncoding

Deprecated. Actual encoding of the document, is a readonly equivalent to encoding.

config

Deprecated. Configuration used when DOMDocument::normalizeDocument() is invoked.

doctype

The Document Type Declaration associated with this document.

documentElement

This is a convenience attribute that allows direct access to the child node that is the document element of the document.

documentURI

The location of the document or null if undefined.

encoding

Encoding of the document, as specified by the XML declaration. This attribute is not present in the final DOM Level 3 specification, but is the only way of manipulating XML document encoding in this implementation.

formatOutput

Nicely formats output with indentation and extra space. This has no effect if the document was loaded with preserveWhitespace enabled.

implementation

The DOMImplementation object that handles this document.

preserveWhiteSpace

Do not remove redundant white space. Default to true. Setting this to false has the same effect as passing LIBXML_NOBLANKS as option to DOMDocument::load() etc.

recover

Proprietary. Enables recovery mode, i.e. trying to parse non-well formed documents. This attribute is not part of the DOM specification and is specific to libxml.

resolveExternals

Set it to true to load external entities from a doctype declaration. This is useful for including character entities in your XML document.

standalone

Deprecated. Whether or not the document is standalone, as specified by the XML declaration, corresponds to xmlStandalone.

strictErrorChecking

Throws DOMException on errors. Default to true.

substituteEntities

Proprietary. Whether or not to substitute entities. This attribute is not part of the DOM specification and is specific to libxml.

警告

Enabling entity substitution may facilitate XML External Entity (XXE) attacks.

validateOnParse

Loads and validates against the DTD. Default to false.

version

Deprecated. Version of XML, corresponds to xmlVersion.

xmlEncoding

An attribute specifying, as part of the XML declaration, the encoding of this document. This is null when unspecified or when it is not known, such as when the Document was created in memory.

xmlStandalone

An attribute specifying, as part of the XML declaration, whether this document is standalone. This is false when unspecified.

xmlVersion

An attribute specifying, as part of the XML declaration, the version number of this document. If there is no declaration and if this document supports the "XML" feature, the value is "1.0".

注释

注意:

此 DOM 扩展采用 UTF-8 编码。在 ISO-8859-1 编码下,使用 utf8_encode()utf8_decode() 来处理,其它编码下使用 iconv 函数处理。

注意:

When using json_encode() on a DOMDocument object the result will be that of encoding an empty object.
