lxmlmeld

A mostly-compatible implementation of Meld3 using lxml as the parsing and serialisation engine.

I previously forked Meld3 and made it use lxml, but the code wasn't elegant as it didn't use much of lxml's additional features. This version is a from-the-ground-up rewrite based on the Meld3 documentation and test suite.

Key Differences

• fillmeldhtmlform() is not implemented (it's rather too magic)
• findwithattrib is not implemented (as unclear how it interacts with namespaces; use lxml's finders or xpath)
• replace() follows the meld3 syntax; the lxml call of the same name is renamed replace_child()
• The property parent doesn't exist; use getparent()
• You can pass lxml Elements or lists of Elements to replace(), content() and fillmelds()
• When using structure=True the content must be broadly parsable as XML
• repeat inserts adjacent to the original node, not at the end of the parent
• doctypes to the write_* functions can be plain strings
