Embed hyperlinks in io.ascii.write html output? #4006
Description
I need to write out the contents of an astropy table to html, using:
ascii.write(sample, 'sample.html', format='html')
some cells of the table need to contain hyperlinks, which I can construct via string:
urlstring = '<a href="file:///linkpath"> linktext </a>'
the problem is that when the string is written out into HTML, the < and > characters are converted to < and >:
<td><a href="file:///linkpath"> linktext </a></td>
How can I have those characters printed into the HTML literally, or otherwise embed links in the html outputs of tables?
Apologies if this is a noob question, but that's what I am.

Hmm--looks like the HTML writer always escapes the raw strings for HTML related characters. However I could see this as an argument for a "raw" mode to just write strings from a table without escaping. If so, I think this should be enabled on a per-column basis.
This would require an update to the
XMLWriterclass to allow data to be written to an element without HTML entity escapes. It would also require an update to theastropy.io.ascii.html.HTMLclass to accept an optional sequence of columns in which to allow raw HTML, and an update toHTML.writeto support that.I think also as a security concern, insecure tags like
<script>or<iframe>should be disabled even in raw HTML mode, unless explicitly whitelisted (this is why I bumped this up to effort-medium).pllim commentedon Jul 24, 2015
Meanwhile,
sedcan be used to manually fix the<a href=...>and</a>tags. http://www.gnu.org/software/sed/manual/sed.html#The-_0022s_0022-Commandmrobberto commentedon Dec 24, 2015
the functionality is present in pandas "to_html" writer. A pandas table "pd" containing html links can be printed to html setting "escape=False"
pd.to_html('fileout.html',escape=False)
Unfortunately, pandas writes vanilla html without sorting headers etc., so it would still be nice to get this added to astropy

c/c @taldcroft ?

Definitely 👍 on the idea. I've wanted this myself a few times, so a PR would definitely be welcome.
