A
Chilkat XML object represents a single node in an XML document.
As long as one node exists referencing the document, the entire
document remains in memory. When the last node referencing a document
is deleted (or garbage collected) the entire document is removed
from memory.
The
root node is always accessible from any document node with the
GetRoot method. GetParent returns the parent node, unless the
node is a root of an entire tree, in which case it returns NULL.
Siblings are available using the NextSibling and PreviousSibling
methods. The TreeId property contains an auto-assigned (non-persistent)
integer value that is the same for all nodes belonging to the
same XML document.
The
XML declaration:
<?xml
version="1.0" encoding="UTF-8" standalone="no" ?>
can
be accessed and modified from any node in the document via the
Encoding and Standalone properties.
Methods
that end in "2", such as GetParent2, NextSibling2, etc.
update the internal reference of the calling node. These methods
allow an XML document to be navigated without the continual creation
of new objects. (Your .NET garbage collector might not need to
run as often...)
