Loadable units for lazy manifestation of XML documents
First Claim
1. A method of lazily manifesting an XML document, the method comprising the steps of:
- receiving a first request that requests a first node;
in response to receiving said first request, manifesting only a portion of said XML document within an in-memory representation of said XML document;
wherein each portion of multiple portions of said XML document belong to a separate loadable unit;
receiving one or more requests for a particular node that is not represented by a node within said in-memory representation and that belongs to a respective loadable unit; and
for each particular request of said one or more requests, incorporating within said in-memory representation a node representing the particular node requested by said each particular request by performing steps that include;
manifesting all nodes that belong to the respective loadable unit, said all nodes that belong to said respective loadable unit including said particular node and one or more other nodes that corresponds to a sibling or descendant element of said particular node.

Abstract
Described herein is a system for “lazy” manifestation of XML documents. In lazy manifestation, only portions of an XML document that contain data of interest (e.g., a particular element or attribute requested by an application) are manifested. The term “manifesting a portion of an XML document” refers to creating an in-memory representation of the portion and incorporating it into existing in-memory representation of an XML document, if any. These portions are referred to herein as a loadable unit. A loadable unit is a set of one or more nodes in an XML document, where when there is need to manifest a node in the set, other nodes in the loadable unit are manifested too. Loadable units may, but not necessarily, correlate to content structures that store the nodes. A loadable unit may be the nodes whose content is contained in a row.
