    • getDocumentURI

      public String getDocumentURI()
      The location of the document or null if undefined or if the Document was created using DOMImplementation.createDocument. No lexical checking is performed when setting this attribute; this could result in a null value returned when using Node.baseURI .
      Beware that when the Document supports the feature "HTML" [DOM Level 2 HTML] , the href attribute of the HTML BASE element takes precedence over this attribute when computing Node.baseURI.

      Since:
      DOM Level 3
    • getStrictErrorChecking

      public boolean getStrictErrorChecking()
      An attribute specifying whether error checking is enforced or not. When set to false, the implementation is free to not test every possible error case normally defined on DOM operations, and not raise any DOMException on DOM operations or report errors while using Document.normalizeDocument(). In case of error, the behavior is undefined. This attribute is true by default.
      Specified by:
      getStrictErrorChecking in interface Document
      Since:
      DOM Level 3
    • getXmlEncoding

      getXmlEncoding in interface Document
      Since:
      DOM Level 3

      getXmlStandalone in interface Document
      Since:
      DOM Level 3
    • getXmlVersion

      Since:
      DOM Level 3

    • renameNode

      public Node renameNode(Node n, String namespaceURI, String qualifiedName) throws DOMException

      Parameters:
      n - The node to rename.
      namespaceURI - The new namespace URI.
      qualifiedName - The new qualified name.
      Returns:
      The renamed node. This is either the specified node or the new node that was created to replace the specified node.
      Throws:
      DOMException - NOT_SUPPORTED_ERR: Raised when the type of the specified node is neither ELEMENT_NODE nor ATTRIBUTE_NODE, or if the implementation does not support the renaming of the document element.
      INVALID_CHARACTER_ERR: Raised if the new qualified name is not an XML name according to the XML version in use specified in the Document.xmlVersion attribute.
      WRONG_DOCUMENT_ERR: Raised when the specified node was created from a different document than this document.
      NAMESPACE_ERR: Raised if the qualifiedName is a malformed qualified name, if the qualifiedName has a prefix and the namespaceURI is null, or if the qualifiedName has a prefix that is "xml" and the namespaceURI is different from " http://www.w3.org/XML/1998/namespace" [XML Namespaces] . Also raised, when the node being renamed is an attribute, if the qualifiedName, or its prefix, is "xmlns" and the namespaceURI is different from "http://www.w3.org/2000/xmlns/".

    • setStrictErrorChecking

      public void setStrictErrorChecking(boolean strictErrorChecking)
      An attribute specifying whether error checking is enforced or not. When set to false, the implementation is free to not test every possible error case normally defined on DOM operations, and not raise any DOMException on DOM operations or report errors while using Document.normalizeDocument(). In case of error, the behavior is undefined. This attribute is true by default.

    • setXmlStandalone

      public void setXmlStandalone(boolean xmlStandalone) throws DOMException
      An attribute specifying, as part of the XML declaration, whether this document is standalone. This is false when unspecified.

      Note: No verification is done on the value when setting this attribute. Applications should use Document.normalizeDocument() with the "validate" parameter to verify if the value matches the validity constraint for standalone document declaration as defined in [XML 1.0].

      Specified by:
      setXmlStandalone in interface Document
      Throws:
      DOMException - NOT_SUPPORTED_ERR: Raised if this document does not support the "XML" feature.
      Since:
      DOM Level 3
    • setXmlVersion

      public void setXmlVersion(String xmlVersion) throws DOMException
      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". If this document does not support the "XML" feature, the value is always null. Changing this attribute will affect methods that check for invalid characters in XML names. Application should invoke Document.normalizeDocument() in order to check for invalid characters in the Nodes that are already part of this Document.
      DOM applications may use the DOMImplementation.hasFeature(feature, version) method with parameter values "XMLVersion" and "1.0" (respectively) to determine if an implementation supports [XML 1.0]. DOM applications may use the same method with parameter values "XMLVersion" and "1.1" (respectively) to determine if an implementation supports [XML 1.1]. In both cases, in order to support XML, an implementation must also support the "XML" feature defined in this specification. Document objects supporting a version of the "XMLVersion" feature must not raise a NOT_SUPPORTED_ERR exception for the same version number when using Document.xmlVersion.
      Specified by:
      setXmlVersion in interface Document
      Throws:
      DOMException - NOT_SUPPORTED_ERR: Raised if the version is set to a value that is not supported by this Document or if this document does not support the "XML" feature.
