XSLT等效于XML到JSON

Question

I have an application where I am parsing an XML document and want to translate it into a JSON document and embed that document directly into MongoDB. Normally going from XML <-> XML I'd use a tool such as XSLT for the translation. Is there currently a decent tool to translate XML -> JSON? Only has to be uni-directional. I won't be translating it back to XML anytime soon. I just want it formatted in a particular state that's embeddable into MongoDB for retrieval and representation to a serializer in the future.

Answer 1

The best available tool for translating XML into JSON, either in general or for a particular vocabulary, is XSLT. Use method="text" on your xsl:output element.

Answer 2

If you don't mind using ActiveSupport and Ruby Hash as intermediary:

require 'active_support/core_ext'
Hash.from_xml(xml).to_json

Note that it would be pretty easy to manipulate the data when it is a Hash if you need to do so.

Also, note that converting XML to a hash can be lossy (when it comes to namespaces and attributes). If you care about this, you might check out other XML parsers (like Crack or CobraVsMongoose ), or use XSLT to do the conversion.
