Research and Realization for Using Tree to Express XML Document Structure

XML has a strong ability of expression to a tree,we can use a tree to express a XML document completely.Operating to a document means operating to a tree,this is Document Object Model(DOM).Actually the fact is also like this,XML file will be shown like a tree no matter you use Internet Explorer or other XML editors to open it.So if we can express XML document by a tree not only it′s structure looks more directly and clear,moreover operate an object is much easier than operate a text.Microsoft has provided the XML object model,this object base allowed you to construct the XML grammar tree,and collect data from different position.This paper will make a deep discussion about how to display a XML document as a tree by using the tool of C#.Net.
