Major Description
There were some changes in the GraphML format between TinkerPop 2 and TinkerPop 3. joshsh has started work on an XSLT to transform between the two formats.
I performed an initial test of the transform using this code within the Gremlin Console.
import javax.xml.parsers.DocumentBuilderFactory
import javax.xml.transform.TransformerFactory
import javax.xml.transform.dom.DOMSource
import javax.xml.transform.stream.StreamSource
import javax.xml.transform.stream.StreamResult
stylesheet = new File('/tmp/tp-graphml-convert.xslt')
datafile = new File('/tmp/tp2-graphml.xml')
outfile = new File('/tmp/tp3-graphml.xml')
tFactory = TransformerFactory.newInstance()
stylesource = new StreamSource(stylesheet)
transformer = tFactory.newTransformer(stylesource)
source = new StreamSource(datafile)
result = new StreamResult(new FileWriter(outfile))
transformer.transform(source, result)

Example TinkerPop 3 GraphML: https://github.com/apache/tinkerpop/blob/3.1.5/data/tinkerpop-classic.xml
