Re: [xml] Dump document to a buffer without xml version

[Iñigo Martínez <inigomartinez gmail com>]

I have find a solution/workaround by using xmlNodeDump with the root node:

xmlBufferPtr buf = xmlBufferCreate();
int size = xmlNodeDump(buf, doc, node, 0, 0);
printf ("%s\n", buf->content);
xmlBufferFree (buf);

I'm not sure if it is the correct way to do it thought.

Best regards,
