Interface IElement

Inherited Members
Namespace: Telerik.Windows.Documents.FormatProviders.Html.Parsing.Dom
Assembly: Telerik.Windows.Controls.RichTextBox.dll

Syntax

public interface IElement : INode

Properties

TagName

The name of the element. For example, in: 

 <elementExample 
id="demo"> ... </elementExample> , 
tagName
has

the value 

"elementExample"
. Note that this is case-preserving in XML, as are all of the operations of the DOM. The HTML DOM returns the 
tagName
of an HTML element in the canonical uppercase form, regardless of the case in the source HTML document.

Declaration
string TagName { get; }
Property Value
System.String

Methods

Declaration
IAttr GetAttributeNode(string name)
Parameters
System.String name

Returns
IAttr

GetAttributeNodeNS(String, String)

Retrieves an 

Attr
node by local name and namespace URI. HTML-only DOM implementations do not need to implement this method.

Declaration
IAttr GetAttributeNodeNS(string namespaceUri, string localName)
Parameters

Returns
IAttr

The 

Attr
node with the specified attribute local name and namespace URI or 
null
if there is no such attribute.

GetAttributeNS(String, String)

string GetAttributeNS(string namespaceUri, string localName)
Parameters
System.String namespaceUri

System.String localName

Returns
System.String

The 

Attr
value as a string, or the empty string if that attribute does not have a specified or default value.

GetElementsByTagName(String)

Returns a 

NodeList
of all descendant

with a given tag name, in the order in which they are encountered in a preorder traversal of this 
Element
tree.

Declaration
INodeList GetElementsByTagName(string name)
Parameters
System.String name

Returns
INodeList

A list of matching 

Element
nodes.

GetElementsByTagNameNS(String, String)

Returns a 

NodeList
of all the descendant 

Elements
with a given local name and namespace URI in

the order in which they are encountered in a preorder traversal of this 

Element
tree.
HTML-only DOM implementations do not need to implement this method.

Declaration
INodeList GetElementsByTagNameNS(string namespaceUri, string localName)
Parameters
System.String namespaceUri

System.String localName

Returns
INodeList

A new 

NodeList
object containing all the matched 

Elements
.

HasAttribute(String)

Returns 

true
when an attribute with a given name is specified on this element or has a default value, 
false
otherwise.

Declaration
bool HasAttribute(string name)

Returns 

true
when an attribute with a given local name and namespace URI is specified on this element or has a default value, 

false
otherwise. HTML-only DOM implementations do not

need to implement this method.

Declaration
bool HasAttributeNS(string namespaceUri, string localName)
Parameters
System.String namespaceUri

System.String localName

Returns
System.Boolean 

true
if an attribute with the given local name 
       and namespace URI is specified or has a default value on this 
       element, <pre><code>false</code></pre> otherwise.

RemoveAttribute(String)

Declaration
void RemoveAttribute(string name)
Parameters
System.String name

RemoveAttributeNode(IAttr)

Removes the specified attribute node. If the removed 

Attr
has a default value it is immediately replaced. The replacing attribute has the same namespace URI and local name, as well as the original prefix, when applicable.

Declaration
IAttr RemoveAttributeNode(IAttr oldAttr)
Parameters
IAttr oldAttr

Returns
IAttr

The 

Attr
node that was removed.
Exceptions
DomException

NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
NOT_FOUND_ERR: Raised if 

oldAttr
is not an attribute of the element.

RemoveAttributeNS(String, String)

Parameters
IAttr newAttr

Returns
IAttr
