Allow docs missing a root element to be created and printed. (@sjp, #126, #121).
xml_add_* methods now return invisibly. (@sjp, #124)
as_list() now preserves element names when attributes exist, and escapes XML attributes that conflict with special R attributes (@peterfoley, #115).
All C++ functions now use checked_get() instead of get() where possible, so NULL XPtrs properly throw an error rather than crashing. (@jimhester, #101, #104).
xml_integer() and xml_double() functions to make it easy to extract integer and double text from nodes (@jimhester, #97, #99).
xml2 now supports modification and creation of XML nodes. New functions xml_new_document(), xml_new_child(), xml_new_sibling(), xml_set_namespace(), , xml_remove(), xml_replace(), xml_root() and replacement methods for xml_name(), xml_attr(), xml_attrs() and xml_text() (@jimhester, #9 #76)

xml_find_one() has been deprecated in favor of xml_find_first() (@jimhester, #58, #92)
xml_read() functions now default to passing the document's namespace object. Namespace definitions can now be removed as well as added and xml_ns_strip() added to remove all default namespaces from a document. (@jimhester, #28, #89)
xml_read() gains a options argument to control all available parsing options, including HUGE to turn off limits for parsing very large documents and now drops blank text nodes by default, mimicking default behavior of XML package. (@jimhester, #49, #62, #85, #88)
xml_write() expands the path on filenames, so directories can be specified with '~/' (@jimhester, #86, #80)
xml_find_one() now returns a 'xml_missing' node object if there are 0 matches (@jimhester, #55, #53, hadley/rvest#82).

xml_name() and xml_text() always correctly encode returned value as UTF-8 (#54).
Improved configure script - now works again on R-devel on windows.
Compiles with older versions of libxml2.,
Make configure script more cross platform.
Add xml_length() to count the number of children (#32).
