svgマークアップの使用には、the DOMDocument classを使用することをおすすめします。あなたの推薦のためのHere's a fiddle.

<?php 

$svg = <<<SVG 
<g class="highcharts-legend" transform="translate(217,262)"> 
    <g clip-path="url(#highcharts-9)"> 
     <g transform="translate(0,0)"> 
      <g class="highcharts-legend-item"><text x="21" y="15"><tspan>1</tspan></text><rect x="0" y="4" width="16" height="12" fill="#f7a35c"></rect></g> 
      <g class="highcharts-legend-item"><text x="21" y="15"><tspan>2</tspan></text><rect x="0" y="4" width="16" height="12" fill="#f7a35c"></rect></g>
