[XXE] Preserving blank space and formatting in #PCDATA?

[Gene Selkov]

Hi Hussein,

I've got a small problem. I hope it is a small problem, as I simply
want XXE not to do something, and I wonder if there is an option I can
set. I want it to keep the exact formatting of the data in the ALT
element. Here's an example:

            <equation label="3">
              <alt role="tex">
\begin{chemistry}[carminsaeure]
%  formula(L,R,"Carmins""aure",HR,24)
  formula(L,R) {
    ring(,,H1=4=){
      vertex(,1,4,H0=2=){ 0: bond(r,,Ln) COOH_;
                     1: bond(r) HO_;
                     3: bond(r) Me_;
                   };
      vertex(,4,1,H3=5=){ 0: bond(r) OH_;
                     3: bond(r) OH_;
                     4: bond(r) atom("CO(CHOH)$_4$CH$_3$",L);
                     5: bond(r) OH_;
                   };
      0: bond(r,=C) O_;
      3: bond(r,=C) O_;
    }
  }
\end{chemistry}
              </alt>
              <graphic fileref="figures/carminsaeure.png"/>
            </equation>


This, when saved to a file, becomes:

<equation label="3">
          <alt role="tex">\begin{chemistry}[carminsaeure] formula(L,R) {
          ring(,,H1=4=){ vertex(,1,4,H0=2=){ 0: bond(r,,Ln) COOH_; 1: bond(r)
          HO_; 3: bond(r) Me_; }; vertex(,4,1,H3=5=){ 0: bond(r) OH_; 3:
          bond(r) OH_; 4: bond(r) atom("CO(CHOH)$_4$CH$_3$",L); 5: bond(r)
          OH_; }; 0: bond(r,=C) O_; 3: bond(r,=C) O_; } } \end{chemistry}
</alt>

          <graphic fileref="figures/carminsaeure.png" />
        </equation></para>


I've got two problems with this. One, the text becomes unreadable.
And, more often than not,  this breaks the TeX syntax.

Is there an easy solution to this?


Thanks,
