为什么这个svg在不同的上下文中呈现不同？

Question

I have the following SVG: http://bensouthgate.com/i/malthus2.svg

Which shows b(y) = d(y)

However, when I embed it in a page: http://bensouthgate.com/p/malthus.php

it shows b(y) = f(y) among other mistakes.

The way I am including it in the page is

<?php include '../i/malthus2.svg'; ?>

What is going on?

Edit: SVG was rendered here -> http://www.tlhiv.org/ltxpreview/

Answer 1

You're embedding more than one SVG directly within your HTML document and therefor the IDs of the various glyphs aren't unique anymore. The ID of the letter d in your second math-SVG is glyph0-2 but glyph0-2 is already defined in your first math-SVG for the letter f.

You have to ensure that all your IDs are absolutely unique if you want to include your SVGs directly in your HTML document.

An alternative would be to include the SVGs via the <img> tag.
