[xml] New programming question.

[Nathanael Noblet <nathanael gnat ca>]

Hello,
	I hope I have the right list for this question. I'm learning the  
libxml library for a project I'm attempting. I've enjoyed the many  
examples, unfortunately, I can't seem to get what I want to happen.  
Here's what I have. Please keep in mind that I am using this as a  
learning experience, and not for the basis of a real program, but to  
learn libxml programming.

static char *methodResponse = "<?xml  
version=\"1.0\"?><methodResponse><params></params></methodResponse>";


then in a test function I parse the above from memory like so

doc =  
xmlReadMemory(methodResponse,strlen(methodResponse),"noname.xml",NULL,0) 
;

I loop through the nodes till xmlStrcmp(cur_node->name,"params")  
returns true. Then I start to construct some more nodes like this

tmp_node = xmlNewNode(NULL,"param");
xmlNewChild(tmp_node,NULL,"int","1");
xmlAddChild(cur_node,tmp_node);


then I write out to a file like so:
xmlSaveFormatFile("path/to/file",doc,0);

What I expect to see is this
<?xml  
version=\"1.0\"?><methodResponse><params><param><int>1</int></param></ 
params></methodResponse>

instead I get
<?xml  
version=\"1.0\"?><methodResponse><params/><param><int>1</int></param></ 
methodResponse>

Is this because when I parse it initially there is nothing in the  
params node so it condenses it down to <params/>? How do I get it to  
add to that node? What do I not understand? Reading material or links  
to help me figure this out would be great.
