	Hello!
	I want to parse an existing XML document. Here is how the XML should
look like:

<options>
    <general>
        <value1>some text</value1>
        <value2>another text</value2>
        <value3>another text 2</value3>
    </options>
</general>

	I remove a node in this way (node is pointing to "general" node):

if ( !xmlStrcmp( node->name, (const xmlChar*)"value2") )
{
	xmlNodePtr node_to_del = node;
	node = node->next;
	
	xmlUnlinkNode( node_to_del );
	xmlFreeNode( node_to_del );
	
	continue;
}

	But when I save the file with xmlSaveFormatFile( CONF_FILE, doc, 1 ) a
blank line appears:

<options>
    <general>
        <value1>some text</value1>
	
        <value3>another text 2</value3>
    </options>
</general>

	I'm inserting a new node in this way (orig_node is same as node):

xmlNewChild( orig_node, NULL, (const xmlChar*)"value4", (const
xmlChar*)"Just another text" );

	And here is the result in saved file:

<options>
    <general>
        <value1>some text</value1>
	
        <value3>another text 2</value3>
    <value3>another text 2</value3></options>
</general>

	There is no problem to parse and edit the file in my program. But I'm
trying to make a config file and it is possible someone to edit it so I
want to make an ordered output.
	What is wrong with my code?
	Thanks in advance!

	Best regards,
	Petyo Milotinov
