Hi,
I wrote a small function for this purpose some time ago.
I didn't test it with the last versions of libxml2 nor did I ensure that this
code if correct but it gives you the idea of a method that you can use to
remove blank nodes.
The usage is for instance:
doc = xmlReadFile (xmlfile, NULL, 0);
if (doc == NULL)
{
/* Deal with error... */
return 1;
}
glbRemoveBlankNodes (xmlDocGetRootElement(doc));
Hope this helps,
Best regards,

int
glbRemoveBlankNodes (xmlNodePtr n)
{
xmlNodePtr cur;
xmlNodePtr next;
if (n == NULL)
return 0;
cur = n->children;
while (cur)
{
next = cur->next;
if (xmlIsBlankNode (cur))
{
xmlUnlinkNode (cur);
xmlFreeNode (cur);
}
else
glbRemoveBlankNodes (cur);
cur = next;
}
return 0;
}
