a question about declaration

[zhefenfei]

when read a file , I wanna save it , invoke -> doc.save(../test.xml). Then ,the declaration is <? version = "1.0">,original declaration is <? version = "1.0" encoding = "utf-8">,just like the encoding has been lost when read file...

By default, declarations are not processed. You need to use parse_default | parse_declaration flag during parsing, which will preserve the declaration node along with all its attributes including encoding.
