Method: LibXML::XML::Reader#encoding

Defined in:
ext/libxml/ruby_xml_reader.c

#encoding ⇒ XML::Encoding::UTF_8

Returns the encoding of the document being read. Note you first have to read data from the reader for encoding to return a value

reader = XML::Reader.file(XML_FILE)
assert_nil(reader.encoding)
reader.read
assert_equal(XML::Encoding::UTF_8, reader.encoding)

In addition, libxml always appears to return nil for the encoding when parsing strings.

Returns:
