What stops you from parsing tokens from a stream like a SAX parser for JSON?

[ ["aaa", "bbb"], { "name", "foo" } ]

    Start array
    Start array
    String aaa
    String bbb
    End array
    Start object
    Key name
    String foo
    End object 
    End array

Nothing, really, but I don’t have the bandwidth to write JSAX. I wonder why it hasn’t already been done by someone more qualified than I am. I suspect that I’d find out, if I started doing it.

You can do that, in a specialized manner, with PHP, and Streaming JSON Parser[0]. I use that, in one of my server projects[1]. It claims to be JSON SAX, but I haven’t really done an objective comparison, and it specializes for file types. It works for my purposes.

Streaming JSON parsers certainly exist. I'm just pointing out there's nothing about JSON that makes it inherently harder to stream than an XML tree.

In response to "Json is just a packing format that does have that [streaming] limitation".
