The return value can be: - if detection of the BOM succeeds, the codec name of the corresponding unicode charset is returned - if BOM detection fails, the xml declaration is searched for the encoding attribute and its value returned. the "<" character has to be the very first in the file then (it's xml standard after all). - if BOM and xml declaration fail, None is returned. According to xml 1.0 it should be utf_8 then, but it wasn't detected by the means offered here. at least one can be pretty sure that a character coding including most of ASCII is used :-/ t utf_32_beiiþiÿt utf_32_let utf_16_bet utf_16_letutf_8iïi»i¿iiÿÿÿÿNis‹ ^<\?xml # w/o BOM, xmldecl starts with # what's matched in the brackets will be named encstr [^"']+ # every character not delimiter (not overly exact!) ) # closes the brackets pair for the named group ["'] # attribute end delimiter .*? # some chars optionally (standalone decl or whitespace) \?> # xmldecl end tencstr(iiiþiÿ(iÿiþii(iþiÿNN(iÿiþNN(iïi»i¿N( tNonettelltseekttupletmaptordtreadtgettretcompiletVERBOSEtsearchtgroup( tfptbomDicttoldFPtbyte1tbyte2tbyte3tbyte4t bomDetectionRtbuffertxmlDeclPatternt xmlDeclREtmatch((sK/data/av2000/b2b/venv/lib/python2.7/site-packages/pyxb/utils/activestate.pytdetectXMLEncoding s6   *!
