Solve the problem that libXML2 does not support Chinese

When using libXML2 to process an XML file, the default load is encoded using UTF-8, so when modifying and saving as GB2312 encoding, you need to convert data to UTF-8 encoding, then modify and save!

Conversion uses iConV, the following is the conversion code

Char * Convertenc (Char * Encfrom, Char * Encto, Const Char * in) {Static Char BUFIN [1024], BUFOUT [1024], * SIN, * SOUT; INT MODE, LENIN, LENOUT, RET, NLINE; ICONV_T C_PT; IF ((c_pt = iconv_open) == (iconv_t) -1) {printf ("iconv_open false:% s ==>% s / n", encfrom, eNCTO); Return null;} iconv (c_pt , NULL, NULL, NULL, NULL); Lenin = Strlen (IN) 1; Lenout = 1024; SIN = (char *) in; sout = bufout; ret = iconv (c_pt, & sin, (size_t *) & lenin, & Sout , (size_t *) & lenout); if (RET == -1) {Return NULL;

}

Iconv_close (c_pt); return bufout;}

The following is an example

Test.xml

Read code

INT main (void) {xmldocptr doc = null; XMLNodePtr Cur = NULL;

DOC = XMLPARSEFILE ("Test.xml"); cur = xmldocgetrootelEment (DOC); Printf ("% S / N", Convert ("UTF-8", "GB2312", (char *) XMLNodeGetContent (CUR)))) } Modify, save the code

TEST2.XML
