What is the difference between str(xslt(doc)) and xslt(doc).write() ?
The str() implementation of the XSLTResultTree class (a subclass of the ElementTree class) knows about the output method chosen in the stylesheet (xsl:output), write() doesn’t. If you call write(), the result will be a normal XML tree serialization in the requested encoding. Calling this method may also fail for XSLT results that are not XML trees (e.g. string results). If you call str(), it will return the serialized result as specified by the XSL transform. This correctly serializes string results to encoded Python strings and honours xsl:output options like indent. This almost certainly does what you want, so you should only use write() if you are sure that the XSLT result is an XML tree and you want to override the encoding and indentation options requested by the stylesheet.
