Implement is in 'xmloff', and each element processing is divided into several steps:
1 )processElement() : Process element 2) _startElement() : Start element 3) processSubContexts() : Sub elements process, if this element is a parent element. Every sub element processing will be divided into three steps. 4)_createChildContext(): Create Sub Context 5)_processSubContext(): Process sub element 7)_collectSubContext(): Collect the sub element's result data 9) _characters(): Process element's content 10)_endElement(): End element
11)commit(): commit the result data to parent element
And every parent element has three solutions to process sub elements:
a) Serial processing
b) Parallel processing
c) delayed processing
In the 'content.xml' stream,
it is 'c)' the top parent element of display element.
In the 'settings.xml/styles.xml' stream,
it is 'b)' the top parent element of setting/style element.
And 'meta.xml', 'settings.xml', 'styles.xml', 'content.xml' It is serial processing.
