[xml] xmlReaderReadOuterXml() and xmlReaderReadInnerXml()

[jwert ilstechnology com]

Hello list,

Here are functional implimentations for xmlReaderReadOuterXml() and
xmlReaderReadInnerXml().

I have tested both and they work, the "inner" version seems to be
overcomplicated, but I don't know the APIs well enough to know what else to
do.  I'm also sure there is some better error checking that I can do, but
again, I'm not familiar with the API to know what I should throw for
errors.

If there are suggestions on how it can be improved, I'll work on it as I
have time, but as Daniel said, some implimentation is better than none. =]

Here is the code:
-----------------------------------
xmlChar *
xmlTextReaderReadInnerXml(xmlTextReaderPtr reader ATTRIBUTE_UNUSED) {
    xmlChar *resbuf;
    xmlNodePtr node,cur_node;
    xmlBufferPtr buff, buff2;
    xmlDocPtr doc;

    xmlTextReaderExpand(reader);
    doc = reader->doc;
    buff = xmlBufferCreate();

for(cur_node=reader->node->children;cur_node!=NULL;cur_node=cur_node->next)
{
            node = xmlDocCopyNode(cur_node, doc, 1);
            buff2 = xmlBufferCreate();
            xmlNodeDump(buff2, doc, node, 0, 0);
            xmlBufferCat( buff, buff2->content);
            xmlFreeNode(node);
            xmlBufferFree(buff2);
    }
    resbuf = buff->content;
    return resbuf;
}

xmlChar *
xmlTextReaderReadOuterXml(xmlTextReaderPtr reader ATTRIBUTE_UNUSED) {
    xmlChar *resbuf;
    xmlNodePtr node;
    xmlBufferPtr buff;
    xmlDocPtr doc;

    node = reader->node;
    doc = reader->doc;
    xmlTextReaderExpand(reader);
    node = xmlDocCopyNode(node, doc, 1);
    buff = xmlBufferCreate();
    xmlNodeDump(buff, doc, node, 0, 0);

    resbuf = buff->content;
    buff->content = NULL;

    xmlFreeNode(node);
    xmlBufferFree(buff);
    return resbuf;
}
