Parsing text nodes

Hi,

I have such XML document:

<rootNode>
    <line>
        <coords>73, 49; 203, 117;</coords>
    </line>
    <line>
        <coords>0, 0; 25, 60; 25, 120; 203, 120;</coords>
    </line>
    <line>
        <coords>73, 30; 235, 30; 235, 107;</coords>
    </line>
</rootNode>

How can I process each (and all) pairs of coordinates? Coordinates are
separated with semicolo and number of pairs in line can vary.
...
<xsl:for-each select="/rootNode/line">
<!-- What should go here to process line coordinates -->
</xsl:for-each>

Any ideas...
