how to write svg file from inkscape ..??

Hello Team,

Now Inkscape Create SVG File Like
<g
     <path
       style="fill:#0000ff;fill-rule:evenodd;stroke:#000000;stroke-width:1px;stroke-linecap:butt;stroke-linejoin:miter;stroke-opacity:1"
       d="M 142.85715,340.93362 L 468.57144,340.93362 L 468.57144,558.07648 L 142.85715,558.07648 z"
       id="rect3097"
       Priority="4" />
    <path
       style="fill:#0000ff;fill-rule:evenodd;stroke:#000000;stroke-width:1px;stroke-linecap:butt;stroke-linejoin:miter;stroke-opacity:1"
       d="M 208.57143,689.50507 L 371.42857,689.50507 L 371.42857,780.93364 L 208.57143,780.93364 z"
       id="rect3099"
       Priority="3" />
  </g>
