Loading XML records into a database

摘要

A method includes receiving a request to store an extensible markup language (XML) document in a repository. The XML document includes a plurality of markup elements. The method includes extracting a plurality of nodes from the XML document. Each node corresponds to a respective one of the plurality of markup elements, and the plurality of nodes are stored in a same memory block. The method further includes determining a set of memory requirements for each node. Each set of memory requirements includes a first memory space required to store a respective node, a second memory space required to store a set of direct child nodes of the respective node, and a third memory space required to store all descendant nodes of the respective node. The method includes storing each node in respective records in the repository based on each corresponding set of memory requirements for each node.

1. A method, comprising:
receiving a request to store an extensible markup language (XML) document in a repository, wherein the XML document comprises a plurality of markup elements; extracting a plurality of nodes from the XML document, wherein each node corresponds to a respective one of the plurality of markup elements; determining a set of respective memory requirements for each node, each set of memory requirements comprising:
a first memory space required to store a respective node;a second memory space required to store a set of direct child nodes of the respective node; anda third memory space required to store all descendant nodes of the respective node; and loading the XML document into the repository, comprising:
loading a first node into a first record;determining whether the memory space of the first record is sufficient to store a second node and descendant nodes of the second node based on the corresponding set of memory requirements of the second node;in response to determining that the memory space of the first record is not sufficient to store the second node and the descendant nodes of the second node, loading the second node into a second record.
