Ah in that case it's still stripping 1 backslash.

Here's a simple bit of maths:
<br><tex src="ax^2 + bx + c"></tex>
<br><br>But you can also do complicated stuff like:
<br><tex src="\\frac{-b \\pm \\sqrt{b^2 - 4ac}}{2a} "></tex>
<br><br><br>Or just keep things simple:
<br><tex src="\\frac{1}{3}"></tex>
<br><br><br>and like this:
<br><tex src="a \\neq 0"></tex>

Ends up as

<br><tex src="ax^2 + bx + c"></tex>
<br><br>But you can also do complicated stuff like:
<br><tex src="\frac{-b \pm \sqrt{b^2 - 4ac}}{2a} "></tex>
<br><br><br>Or just keep things simple:
<br><tex src="\frac{1}{3}"></tex>
<br><br><br>and like this:
<br><tex src="a \neq 0"></tex>

In preview.xml - data.xml shows the same after clicking publish

When just using just one slash in the editor there are no slashes in the XML – or when re-edited.

When using two, the Xml shows one – and so does the editor when re-opened, but then the preview doesn’t work. Publish, close the re-edit and finally all slashes are gone!


MAGIC!

OK, we so we know it is down to how the editor opens the file. That’s good detective work. It is not happening here. We need to dig around in the process by which the file is opened. Just to check:

If you do it as it should be, i.e. with one slash, what do you see in the saved .xml file on the server? One slash?
And what happens if you then re-edit that file (so it now breaks) and exit again?

- open the editor, make some working latex;
- preview – it works, right?
- don’t close the editor
- make it public, set access rights, publish it
- now hit it using the play_wxyz url as your end users would hit it.

DONE.

The LO works when using the play URL – and even when the editor is closed. The changes seem to save, right up until you attempt to re-open the editor and publish – then it seems to strip out the slashes and latex breaks. Of course, needing to constantly re-edit is a bit of a pain!!

That’s the puzzling bit. The file is saved when previewed, so it’s not how the file is being saved, it’s how the file is being opened: try this:

- open the editor, make some working latex;
- preview – it works, right?
- don’t close the editor
- make it public, set access rights, publish it
- now hit it using the play_wxyz url as your end users would hit it.

That fails (because we have just loaded up the xml)?
But preview still works (because we haven’t just loaded up the xml)?

Double use of HTML chars seems to break the latex whereas \\ or \\ works (until the editor is closed).

Hi Julian



Thanks for the suggestion. It does look like it's something to do with Windows messing around with the "\"s. I've managed to fiddle around to get it to display correctly:



It would appear double \\ is needed before special characters:



<tex src="ax^2 + bx + c"></tex>

<br><br>are given by the formula

<br><tex src="\\frac{-b \\pm \\sqrt{b^2 - 4ac}}{2a} <file:///\\frac%7b-b%20\pm%20\sqrt%7bb%5e2%20-%204ac%7d%7d%7b2a%7d%20> "></tex>

<br><br><br>where

<br><tex src="\\frac{1}{3}<file:///\\frac%7b1%7d%7b3%7d>"></tex>

<br><br><br>where

<br><tex src="a \\neq<file:///\\neq> 0"></tex>



Which then outputs:



[cid:image001.png at 01CBBD56.7B6513D0]



I don’t suppose there is another work around for this? I’m sure staff could get used to adding the extra “\”s where needed.



Cheers, Adam

After a bit of pre-processing the url that is called is:



latex[1] = 'http://www.forkosh.dreamhost.com/mathtex.cgi?\\png ' + escape(latex[1]) + '#.png';



where latex[1] is the src string, so this returns an image:



http://www.forkosh.dreamhost.com/mathtex.cgi?\png%20e=mc^2#.png<http://www.forkosh.dreamhost.com/mathtex.cgi?\png%20e=mc%5e2#.png>



A simple fraction

http://www.forkosh.dreamhost.com/mathtex.cgi?\png%20\frac{1}{3}#.png<http://www.forkosh.dreamhost.com/mathtex.cgi?\png%20\frac%7b1%7d%7b3%7d#.png>



the #.png is for flash, otherwise it doesn't know an image is coming back, and won't try and display one, so directly in the browser you can do this:

http://www.forkosh.dreamhost.com/mathtex.cgi?\png%20\frac{1}{3}<http://www.forkosh.dreamhost.com/mathtex.cgi?\png%20\frac%7b1%7d%7b3%7d>



It does appear that your '\' is being lost, i.e. not escaped on the way through somewhere.

Hello,



Xot has always generated one red error when it loads a project. Never sure why.



As for the problem, and by looking at the latex construction it would seem that the \ character isn't being sent properly.



Adam, your server is windows, so it may send it in a different way. Julian could you send Adam a URL with the latex as a string so he can access it directly and see what happens.



Failing that, click on the latex URL in fiddler and some new panels appear on the right hand side. One of those will show exactly what data has been sent.



If these fail, on the rising of the sun on Tuesday morning, look west and I shall appear ________________________________________

Subject: [Xerte] Re: Math Symbols



It’s not my project. I did look at the raw xml, but it has a load of escaped characters in there which make it more difficult to copy / paste into a mail.  I have sent your message to the owner of the project.

Subject: [Xerte] Re: Math Symbols



No chance of seeing the text as it appears in that Xerte LO?!



That document doesn’t really help at the moment as I can’t replicate the examples in Xerte until im sure what to include and what not to!



For example, the document tells you to write:



\documentclass{article}

\begin{document}

The square root of two: $\sqrt{2}$. I can type math!

\end{document}



To output:



[cid:image011.png at 01CBB980.AC292080]<mailto:[cid:image011.png at 01CBB980.AC292080]>



But in Xerte



<tex src="\documentclass{article}

\begin{document}

The square root of two: $\sqrt{2}$. I can type math!

\end{document}

">



Renders:



[cid:image012.png at 01CBB980.AC292080]<mailto:[cid:image012.png at 01CBB980.AC292080]>



And



<tex src="The square root of two: $\sqrt{2}$. I can type math!"> renders:



[cid:image013.png at 01CBB980.AC292080]<mailto:[cid:image013.png at 01CBB980.AC292080]>



<tex src="$\sqrt{2}$"> just renders:



[cid:image014.png at 01CBB980.AC292080]<mailto:[cid:image014.png at 01CBB980.AC292080]>



Any ideas? I could probably work out what I’m missing from that example Nottingham LATEX LO!

I don’t think there is anything ‘funny’ about the latex service we use. It is a third party service though, but we are working to implementing it ourselves,

Any chance of seeing the LATEX code to generate these equations:



http://www.nottingham.ac.uk/toolkits/play_595



My LO doesn’t seem to want to do fancy graphic ones (e.g. special chars) – do you need to tell latex to load a set of chars? I can get it to render things like e=mc2 but not much else:

Bl***y maths…



I’ve tried doing



<tex src="\usepackage{amsmath}”> to no avail.

Subject: [Xerte] Math Symbols



Hi all



Is anyone using Math / Scientific symbols in Xerte? I’ve had a request for help from a Maths lecturer who needs to use symbols.



I’ve had a go using <sub> and <sup> which works in XOT with “allow subscripts” ticked, and also came across an earlier list post pointing out HTML chars which seem to work, but I also came across some reference to Latex.



Does latex work in XOT? Last I read it seemed some service you chaps used had crashed?



If there is an easier way than using HTML syntax then let me know. I guess another alternative would be to use some other software and save them as images.



Cheers, Adam
