Hello, I have a simple SVG graph generated by GraphViz:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN"
"http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
<!-- Generated by graphviz version 2.26.3 (20100126.1600)

<!-- Title: G Pages: 1 -->
<svg width="138pt" height="168pt"
viewBox="0.00 0.00 138.00 168.00" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
<g id="graph1" class="graph" transform="scale(1 1) rotate(0) translate(4 164)">
<title>G</title>
<polygon fill="white" stroke="white" points="-4,5 -4,-164 135,-164 135,5 -4,5"/>
<!-- Node1 -->
<g id="node1" class="node"><title>Node1</title>
<a xlink:href="http://localhost/viz/applet.php" xlink:title="Internet">

<text text-anchor="middle" x="65" y="-116.4" font-family="Times New Roman,serif" font-size="14.00">'.$Internet.'</text>
</a>
</g>

<path fill="none" stroke="black" d="M65,-82.2678C65,-73.5404 65,-64.358 65,-55.8964"/>
<polygon fill="black" stroke="black" points="68.5001,-55.6524 65,-45.6524 61.5001,-55.6525 68.5001,-55.6524"/>
</a>

</g>
</svg>
I want to change some atributes: for example " VOIP calls: 4 "
-changing "4" to value from Database(LDAP) without refreshing whole SVG graph
<a xlink:title="Bandwidth: 1544kbps Using link: 12% VOIP calls: 4 Packet rate: 10000 Packet loss: 2">
Thank you for your answers
