DOM Processing Instruction class.
The ProcessingInstruction interface represents a "processing instruction", used in XML as a way to keep processor-specific information in the text of the document.

CL_DomProcessingInstruction::CL_DomProcessingInstruction | ( | ) |
Constructs a DOM Processing Instruction handle.
CL_DomProcessingInstruction::CL_DomProcessingInstruction | ( | CL_DomDocument & | doc, |
const CL_DomString & | target, | ||
const CL_DomString & | data | ||
) |
Constructs a DomProcessingInstruction.
doc | = Dom Document |
target | = Dom String |
data | = Dom String |
CL_DomProcessingInstruction::CL_DomProcessingInstruction | ( | const CL_SharedPtr< CL_DomNode_Generic > & | impl) |
Constructs a DomProcessingInstruction.
impl | = Shared Ptr |
CL_DomProcessingInstruction::~CL_DomProcessingInstruction | ( | ) |
|
inherited |
Adds the node new_child to the end of the list of children of this node.
If the new_child is already in the tree, it is first removed.
|
inherited |
Returns a duplicate of this node, i.e., serves as a generic copy constructor for nodes.
The duplicate node has no parent.
Cloning an Element copies all attributes and their values, including those generated by the XML processor to represent defaulted attributes, but this method does not copy any text it contains unless it is a deep clone, since the text is contained in a child Text node. Cloning any other type of node simply returns a copy of this node.
deep | If true, recursively clone the subtree under the specified node; if false, clone only the node itself (and its attributes, if it is an Element). retval: The duplicate node. |
|
inherited |
Searches the node tree upwards for the namespace URI of the given qualified name.
|
inherited |
Searches the node tree upwards for the prefix name for the namespace URI.
|
inherited |
A NamedNodeMap containing the attributes of this node (if it is an Element) or null otherwise.
|
inherited |
Returns a NodeList that contains all children of this node.
If there are no children, this is a NodeList containing no nodes. The content of the returned NodeList is "live" in the sense that, for instance, changes to the children of the node object that it was created from are immediately reflected in the nodes returned by the NodeList accessors; it is not a static snapshot of the content of the node. This is true for every NodeList, including the ones returned by the getElementsByTagName method.
CL_DomString CL_DomProcessingInstruction::get_data | ( | ) | const |
The content of this processing instruction.
This is from the first non white space character after the target to the character immediately preceding the ?>.
|
inherited |
The first child of this node.
If there is no such node, this returns a null node.
|
inherited |
The last child of this node.
If there is no such node, this returns a null node.
|
inherited |
Returns local part of the qualified name of this node.
For nodes of any type other than ELEMENT_NODE and ATTRIBUTE_NODE and nodes created with a DOM Level 1 method, such as create_element from the Document interface, this is always an empty string.
|
inherited |
Returns the namespace URI of this node.
|
inherited |
The node immediately following this node.
If there is no such node, this returns a null node.
|
inherited |
Returns the node name.
The return value vary according to the node type as follows:
|
inherited |
Returns the node type (one of those in the NodeType enum).
|
inherited |
Returns the node value.
The return value vary according to the node type as follows:
|
inherited |
The Document object associated with this node.
This is also the Document object used to create new nodes. When this node is a Document this is null.
|
inherited |
Returns the parent of this node.
All nodes, except Document, DocumentFragment, and Attr may have a parent. However, if a node has just been created and not yet added to the tree, or if it has been removed from the tree, this is null.
|
inherited |
Returns the namespace prefix of the node.
For nodes of any type other than ELEMENT_NODE and ATTRIBUTE_NODE and nodes created with a DOM Level 1 method, such as create_element from the Document interface, this is always an empty string.
|
inherited |
The node immediately preceding this node.
If there is no such node, this returns a null node.
CL_DomString CL_DomProcessingInstruction::get_target | ( | ) | const |
The target of this processing instruction.
XML defines this as being the first token following the markup that begins the processing instruction.
|
inherited |
Returns true if this node (if its an element) has any attributes.
|
inherited |
Returns true if this node has any children.
|
inherited |
Inserts the node new_child before the existing child node ref_child.
If refChild is a null node, inserts new_child at the end of the list of children.
If newChild is a DocumentFragment object, all of its children are inserted, in the same order, before ref_child. If the new_child is already in the tree, it is first removed.
new_child | The node to insert. |
ref_child | The reference node, i.e., the node before which the new node must be inserted. retval: The node being inserted. |
|
inherited |
Returns true if this is an attribute node.
|
inherited |
Returns true if this is a CDATA section node.
|
inherited |
Returns true if this is a comment node.
|
inherited |
Returns true if this is a document node.
|
inherited |
Returns true if this is a document fragment node.
|
inherited |
Returns true if this is a document type node.
|
inherited |

|
inherited |
Returns true if this is an entity node.
|
inherited |
Returns true if this is an entity reference node.
|
inherited |
Returns true if this is a notation node.
|
inherited |
Returns true if this is a null node.
|
inherited |
Returns true if this is a processing instruction node.
|
inherited |
Tests whether the DOM implementation implements a specific feature and that feature is supported by this node.
|
inherited |
Returns true if this is a text node.
|
inherited |
Returns the first child node with the specified node name.
Returns a null node if no child is found.
|
inherited |
Retrieves the first child node with the specified namespace URI and local name.
|
inherited |
Merges any adjacent Text nodes.
Puts all Text nodes in the full depth of the sub-tree underneath this node, including attribute nodes, into a "normal" form where only structure (e.g., elements, comments, processing instructions, CDATA sections, and entity references) separates Text nodes, i.e., there are neither adjacent Text nodes nor empty Text nodes.
This can be used to ensure that the DOM view of a document is the same as if it were saved and re-loaded, and is useful when operations (such as XPointer lookups) that depend on a particular document tree structure are to be used.
Note: In cases where the document contains CDATASections, the normalize operation alone may not be sufficient, since XPointers do not differentiate between Text nodes and CDATASection nodes.

Compare operator.
|
inherited |
Compare operator.
|
inherited |
Removes the child node indicated by old_child from the list of children, and returns it.
|
inherited |
Replaces the child node old_child with new_child in the list of children.
If the new_child is already in the tree, it is first removed.
new_child | The new node to put in the child list. |
old_child | The node being replaced in the list. retval: The node replaced. |

void CL_DomProcessingInstruction::set_data | ( | const CL_DomString & | data) |
Set data.
data | = Dom String |
|
inherited |
Sets the node value.
|
inherited |
Sets the namespace prefix of the node.
Note that setting this attribute, when permitted, changes the node_name attribute, which holds the qualified name, as well as the tag_name and name attributes of the Element and Attr interfaces, when applicable.
Note also that changing the prefix of an attribute that is known to have a default value, does not make a new attribute with the default value and the original prefix appear, since the namespace_uri and local_name do not change.
|
inherited |
Returns the Attribute interface to this node.
If the node is not an Attribute node, then it returns a null node.
|
inherited |
Returns the CDATA Section interface to this node.
If the node is not a CDATA Section node, then it returns a null node.
|
inherited |
Returns the Comment interface to this node.
If the node is not a Comment node, then it returns a null node.
|
inherited |
Returns the Document interface to this node.
If the node is not a Document node, then it returns a null node.
|
inherited |
Returns the Document Fragment interface to this node.
If the node is not a DocumentFragment node, then it returns a null node.
|
inherited |
Returns the Document Type interface to this node.
If the node is not a Document Type node, then it returns a null node.
|
inherited |
Returns the Element interface to this node.
