将大型xml数据集导入symfony2应用程序

Question

I have a fairly large xml file - 7G - to import into a symfony2 app, storing in mongodb.

Are there any symfony2 components, or preferred ways to do this?

Answer 1

Try XMLReader - http://www.php.net/manual/en/book.xmlreader.php .

As far as I know XMLReader streams the file rather than reading the whole file in before doing anything with it.

From there you can convert it to a simplexml object if you would prefer it like http://posterous.richardcunningham.co.uk/using-a-hybrid-of-xmlreader-and-simplexml

Not sure about a Symfony specific component though.
