Hi,

 

Note that the built-in XML data source implementation uses DOM to parse the XML content. If you are using large amounts of XML data, then this XML data source is not recommended, as the DOM model is all kept in memory.

 

You should try implement a custom-made XML data source that parses your XML data using SAX, which would allow you to workaround the memory limitations.

 

If you want to know more about implementing data sources, you could take a look at the implementations that we ship with our product, including the ones in the /demo/sample/datasource sample.

 

I hope this helps.
