# Titanium.XML.Comment
Represents the contents of an XML comment.
# Overview
Implements the DOM Level 2 API (opens new window) on Android and iOS with some non-standard extensions.
# Properties
# apiName READONLY
The name of the API that this proxy corresponds to.
The value of this property is the fully qualified name of the API. For example, Titanium.UI.Button
returns Ti.UI.Button
.
# attributes READONLY
A map of this node's attributes.
As defined by the DOM specification, only Titanium.XML.Element nodes have attributes.
For all other node types, this property is always null
.
# bubbleParent
Indicates if the proxy will bubble an event to its parent.
Some proxies (most commonly views) have a relationship to other proxies, often established by the add() method. For example, for a button added to a window, a click event on the button would bubble up to the window. Other common parents are table sections to their rows, table views to their sections, and scrollable views to their views. Set this property to false to disable the bubbling to the proxy's parent.
Default: true
# childNodes READONLY
A Titanium.XML.NodeList of this node's children.
# data
The character data of the node that implements this interface. Throws an exception during setting if this node is readonly.
# length READONLY
The number of characters that are available through data and the substringData method. This may have the value zero, i.e., Titanium.XML.CharacterData may be empty.
# lifecycleContainer
The Window or TabGroup whose Activity lifecycle should be triggered on the proxy.
If this property is set to a Window or TabGroup, then the corresponding Activity lifecycle event callbacks will also be called on the proxy. Proxies that require the activity lifecycle will need this property set to the appropriate containing Window or TabGroup.
# localName
Local part of the qualified name of this node.
The local part of the qualified name that comes after the colon. That is, the name without the namespace prefix.
# nodeName READONLY
Name of this node.
Certain node types have constant values defined by the DOM specification:
- Text node:
#text
- Comment node:
#comment
- CDATA section node:
#cdata-section
- Document node:
#document
- Document fragment node:
#document-fragment
# nodeType READONLY

, CDATA_SECTION_NODE
,
ENTITY_REFERENCE_NODE
, ENTITY_NODE
, PROCESSING_INSTRUCTION_NODE
, COMMENT_NODE
,
DOCUMENT_NODE
, DOCUMENT_TYPE_NODE
, DOCUMENT_FRAGMENT_NODE
, NOTATION_NODE
.
# nodeValue
Content (value) of this node.
As defined in the DOM specification, the node value is always null
for
Document, DocumentFragment, DocumentType, Element, Entity, EntityReference, and
Notation nodes.
# ownerDocument READONLY
This node's owning document.
Note that a node always has an owning document, even if it is not part of the document tree.
For more on node ownership, see ownerDocument issues in the W3C DOM FAQ.
# prefix
Namespace prefix of this node.
Read-only on iOS, read-write on other platforms.
# text READONLYDEPRECATED
DEPRECATED SINCE 2.0.0
Use textContent instead.
Content (value) of all text nodes within this node.

Remove a range of characters from the node. Upon success, data and length reflect the change. Throws an exception if this node is readonly, if offset is negative, offset is beyond the data's length, or if count is negative.
Parameters
Name | Type | Description |
---|---|---|
offset | Number | The offset from which to start removing. |
count | Number | The number of characters to delete. If the sum of offset and count exceeds length then all characters from offset to the end of the data are deleted. |
Returns
- Type
- void
# fireEvent
Fires a synthesized event to any registered listeners.
Parameters
Name | Type | Description |

# removeEventListener
Removes the specified callback as an event listener for the named event.
Multiple listeners can be registered for the same event, so the
callback
parameter is used to determine which listener to remove.
When adding a listener, you must save a reference to the callback function in order to remove the listener later:
var listener = function() { Ti.API.info("Event listener called."); }
window.addEventListener('click', listener);
To remove the listener, pass in a reference to the callback function:
window.removeEventListener('click', listener);

---|---|---|
name | String | Name of the event. |
callback | Callback<Titanium.Event> | Callback function to remove. Must be the same function passed to |
