ProcessingInstruction class

The class represents a “processing instruction”, used in XML as a way to keep processor-specific information in the text of the document.

Inheritance: ProcessingInstruction → CharacterData → Node

The ProcessingInstruction type exposes the following members:

Property	Description
node_type	Gets the node type.
parent_node	Gets the parent node.
base_uri	Gets the absolute base URI of this node or null if the implementation wasn’t able to obtain an absolute URI.
owner_document	Gets the document object associated with this node.
child_nodes	Gets the child nodes.
node_name	Gets the name of this processing instruction.
node_value	Gets or sets the value of this node, depending on its type.
text_content	Gets or sets the the text content of this node and its descendants.
local_name	Gets the local part of the qualified name of this node.
prefix	Gets or sets the namespace prefix of this node.
namespace_uri	Gets the namespace URI of this node.
has_child_nodes	Gets whether this node has any children.
previous_sibling	Gets the node immediately preceding this node. If there is no such node, this returns null.
next_sibling	Gets the node immediately following this node. If there is no such node, this returns null.
first_child	Gets the first child of this node. If there is no such node, this returns null.
last_child	Gets the last child of this node. If there is no such node, this returns null.

length	Gets the number of 16-bit units that are available through data. This may have the value zero, i.e., CharacterData nodes may be empty.
data	Gets or sets the character data of the node that implements this interface.

Method	Description
append_child(node)	Adds the node newChild to the end of the list of children of this node.
remove_child(node)	Removes the child node indicated by old child from the list of children.
replace_child(node, child)	Replaces the child node old child with new child in the list of children, and returns the old child node.
substring(offset, count)	Extracts a range of data from the node.
append_data(data)	Appends the string to the end of the character data of the node.
insert_data(offset, data)	Inserts a string at the specified offset.
delete_data(offset, count)	Removes a range of content from the node.
replace_data(offset, count, data)	Replaces the characters starting at the specified offset with the specified string.
