Hi Today I played with xml_recv function and with xml processing functions.
xml_recv function ensures correct encoding from document encoding to server encoding. But the decl section holds original encoding info - that should be obsolete after encoding. Sometimes we solve this issue by removing decl section - see the xml_out function. Sometimes we don't do it - lot of functions uses direct conversion from xmltype to xmlChar. Wrong encoding in decl section can breaks libxml2 parser with error ERROR: could not parse XML document DETAIL: input conversion failed due to input error, bytes 0x88 0x3C 0x2F 0x72 line 1: switching encoding: encoder error This error is not often - but it is hard to find it - because there is small but important difference between printed XML and used XML. There are possible two fixes a) clean decl on input - the encoding info can be removed from decl part b) use xml_out_internal everywhere before transformation to xmlChar. pg_xmlCharStrndup can be good candidate. Comments? Regards Pavel
