Reading SVG file using PHP

[Anon]

Hello everyone,

I am trying to list all the ids in <g> tags between <!-- Map Layers --> and <!-- Map Layers End --> comments in my SVG file using PHP. my sample svg file looks like this.

<svg>
<g id="resources">.....</g>

<!-- Map Layers -->
<g id="abc">......</g>
<g id="xyz">......</g>
<g id="upy">......</g>
<!-- Map Layers End -->

<g id="whatever">....</g>
</svg>

Can anyone tell me what should I do? Any help in this regard is highly appreciated.

Thanks,
Irfan
