XML forming question

[jounindude]

Here is some XML I made. I keep getting a not well formed error. What's wrong (ignore the absence of style info and a DTD):

<?xml version="1.0" encoding="UTF-8"?><geometry><coordplane><point><x="3"/><y="7"/></point><line><m="1"/><b="4"/></line><segment id="segment1"><x1="2"/><y1="2"/><x2="5"/><y2="3"/></segment></coordplane></geometry>

What exactly are you thinking with

<x="3"/><y="7"/>

<m="1"/><b="4"/>

<x1="2"/><y1="2"/><x2="5"/><y2="3"/>

?XML doesn't have such a construct.You could write those down as elements, i.e.

<x>3</x><y>7</y>

<m>1</m><b>4</b>

<x1>2</x1><y1>2</y1><x2>5</x2><y2>3</y2>

or as attributes to their parent element, i.e.

<point x="3" y="7" />

<line m="1" b="4" />

<segment id="segment1" x1="2" y1="2" x2="5" y2="3" />

or maybe, just maybe, as arributes in a new element, like for example "coordinate", i.e.

<coordinate x="3" y="7" />

<coordinate m="1" b="4" />

<coordinate id="segment1" x1="2" y1="2" x2="5" y2="3" />

Pretty much anything else. Your current construct simply doesn't exist in XML.
