Re: Parsing large file

[John Harrison]

 

So, this means similar to XMLBeans.

 

I undersand the reason why XMLBean does this( Loading everything in memory) to preserve the sequence so that it is easy to traverse back and forth.

 

But for me it is too every expensive to put everything in memory.(500,000-750,000 objects)

I guess I have look for alternate parse, Unless some one suggest that this can be achieved using XMLBeans!

 

Regards

John

From vtd-xml.sourceforge.net:

"Its memory usage is typically between 1.3x~1.5x the size of the XML
document, with 1 being the XML itself."

Which implies storing it in memory as well?
