由于对libxml2的不熟悉,发表了“LibXML2不支持中文”一文。经过不断的接触,发现LibXML2自身已经支持了中文编码.只是他的所有api 处理的数据都是UTF-8类型的,所以只要在读入和写入数据时进行相应转换即可!而且libxml2已融合了iconv,以下是代码!flags标示是读入(0)还是写入(1)!已测试通过
uint8_t *convert(uint8_t *in, char *encoding, uint8_t flags)
{
uint8_t *out;
int ret, size, out_size, temp;
xmlCharEncodingHandlerPtr handler;
size = (int) strlen( (char*)in ) + 1;
out_size = size * 2 - 1;
out = (uint8_t *)malloc((size_t) out_size);
if (out) {
handler = xmlFindCharEncodingHandler(encoding);
if (!handler) {
free(out);
out = NULL;
}
}
if (out) {
temp = size - 1;
if ( flags ) {
ret = handler->input(out, &out_size, in, &temp);
}else {
ret = handler->output(out, &out_size, in, &temp);
}
if (ret || temp - size + 1) {
if (ret) {
printf(\"conversion wasn't successful.\\n\");
} else {
printf(\"conversion wasn't successful. converted: \");
}
free(out);
out = NULL;
} else {
out =(uint8_t *) realloc(out, out_size + 1);
out[out_size] = 0; /*null terminating out */
}
} else {
printf(\"no mem\\n\");
}
return (out);
}
int main(int argc, char **argv)
{
uint8_t *content, *out, *in;
xmlDocPtr doc;
xmlNodePtr rootnode;
char *encoding = \"ISO-8859-1\";
//char *encoding = \"utf-8\";
if (argc <= 1) {
printf(\"Usage: %s content\\n\", argv[0]);
return (0);
}
content = (uint8_t *)argv[1];
out = convert(content, encoding, 1);
in = convert( out, encoding, 0 );
doc = xmlNewDoc( (xmlChar*)\"1.0\" );
printf( \"%s:%s\\n\", encoding, out );
printf( \"%s:%s\\n\", encoding, in );
