SVG parsing faulty

[coolum001]

Hi

First: Thank you for this plugin: I find it very useful

Second:

I am trying to include SVG images created by graphviz in a Notebook to be rendered in Pelican, using the %%svg cell magic

The cell input I am using as an example:

%%svg
<svg width="62pt" height="116pt"
 viewBox="0.00 0.00 62.00 116.00" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
<g id="graph0" class="graph" transform="scale(1 1) rotate(0) translate(4 112)">
<title>%3</title>
<polygon fill="white" stroke="none" points="-4,4 -4,-112 58,-112 58,4 -4,4"/>
<!-- a -->
<g id="node1" class="node"><title>a</title>
<ellipse fill="none" stroke="black" cx="27" cy="-90" rx="27" ry="18"/>
<text text-anchor="middle" x="27" y="-86.3" font-family="Times New Roman,serif" font-size="14.00">a</text>
</g>
<!-- b -->
<g id="node2" class="node"><title>b</title>
<ellipse fill="none" stroke="black" cx="27" cy="-18" rx="27" ry="18"/>
<text text-anchor="middle" x="27" y="-14.3" font-family="Times New Roman,serif" font-size="14.00">b</text>
</g>
<!-- a&#45;&gt;b -->
<g id="edge1" class="edge"><title>a&#45;&gt;b</title>
<path fill="none" stroke="black" d="M27,-71.6966C27,-63.9827 27,-54.7125 27,-46.1124"/>
<polygon fill="black" stroke="black" points="30.5001,-46.1043 27,-36.1043 23.5001,-46.1044 30.5001,-46.1043"/>
</g>
</g>
</svg>

This is rendered as expected in my Jupyter Lab notebook, and is generated by the simplest graphviz digraph (via dot)

digraph { a->b }

The following is a snip from the output HTML file created by Pelican (with plugin).

<div class="output_svg output_subarea ">
<svg height="116pt" viewbox="0.00 0.00 62.00 116.00" width="62pt" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
<g class="graph" id="graph0" transform="scale(1 1) rotate(0) translate(4 112)">
<title>%3
<polygon fill="white" points="-4,4 -4,-112 58,-112 58,4 -4,4" stroke="none" />
<!-- a -->
<g class="node" id="node1"><title>a
<ellipse cx="27" cy="-90" fill="none" rx="27" ry="18" stroke="black" />
<text font-family="Times New Roman,serif" font-size="14.00" text-anchor="middle" x="27" y="-86.3">a</text>
</g>
<!-- b -->
<g class="node" id="node2"><title>b
<ellipse cx="27" cy="-18" fill="none" rx="27" ry="18" stroke="black" />
<text font-family="Times New Roman,serif" font-size="14.00" text-anchor="middle" x="27" y="-14.3">b</text>
</g>

You will notice that the <title> tags are not closed, which means the svg image is not shown. Manually editing the HTML file to close the <title> tags works fine. Note that the <title> tags are closed in the input svg.

Maybe there is special processing for <title> tag, assuming it is HTML, and not recognising that an SVG <title> tag is different?

I am running JupyterLab 1.2.4, Pelican 3.7.1, the plugin was downloaded at 2 Aug 2019

Happy to supply more info if needed
