I am using htlatex to convert TeX to HTML output.

I try to keep the LaTeX equations unchanged when using the \[...\] command.

my cfg:

\Preamble{xhtml,mathml,NLM,-xtpipes,NoFonts,refcaption,DocBook}

\newtoks\eqtoks 
\def\AltMath#1\]{\eqtoks{\[#1\]}% 
   \HCode{\the\eqtoks}}
\Configure{[]}{\expandafter\AltMath}{} 

\begin{document}
\EndPreamble

But i am not getting the required equivalent of the LaTeX code in the HTML output. Lots of errors are reported during the compilation:

How to rectify the errors? How to get the HTML equivalent of the LaTeX Math coding? Please advise.

  • i've edited the text of the question, since your native language is most likely not english. if i have misinterpreted your intention, please point out the problems and i'll be happy to fix them. – barbara beeton Jun 22 '16 at 13:50
  • is this question resolved? – Runar Jun 30 '16 at 11:58

I think all of your errors here are simply the same error repeated over and over. You use a lot of \[math\] which is used for displaymath, when I think you really want inline math, with \(math\). And I don't think this question has much to do with htlatex since the document won't compile anyway. Have a look at Are ( and ) preferable to dollar signs for math mode?

Here I just simply replaced all instances of \[ and \] with the correspending \( and \). You should also replace any $math$-pair, according to mentioned article. It might be this is not how you intended it to look like, but I'm not psychic.

I also commented out the usage of the caption-package, cannot really see that you are using it directly, and it threw an error on the command htlatex file.tex, but after commenting it out, no error was produced.

Note: I have zero experience with htlatex, and even thought I did manage to produce a working .html-file as requested without any errors, somebody with more experience should elaborate.

Note that fixltx2e is not needed anymore, for releases beyond 2015.Loading it will just throw this warning:

Package fixltx2e Warning: fixltx2e is not required with releases after 2015 (fixltx2e) All fixes are now in the LaTeX kernel.

You have also an overfull \hbox. Since you are producing a '.html'-file, I don't think it matters.

  • @runatrollet I need a two output 1)math should be converted MathML Code 2) and the same math latex code is needed. so i am using this above option \[ \]. Now i am changing as per your ideas like \[ \] replaced \( \) . fixltx2e to be comment. Change cfg file \[ \] to \( \). I am using the compilation commands like htlatex sam.tex my. But still the error to be throw ! Missing $ inserted. How to rectify this issue. please advice – CS Kumar Jun 22 '16 at 09:48
  • I commented out \usepackage{caption} from my answer since it ran an error on htlatex file.tex and then it produced an html file, which seems to be a correct file. – Runar Jun 22 '16 at 13:18
