counting characters when dealing with XML

counting characters when dealing with XML

[Pablo Rodriguez]

Dear list,

I have a question when dealing with XML.

Is there any way to write a conditional based on the number of
characters in a given field?

I mean, the following field:

    \xmltext{#1}{h1[@class='subtitle']}

If subtitle > 60 chars, then fontsize = 10pt.
If subtitle > 50 chars, then fontsize = 12pt.
If subtitle > 40 chars, then fontsize = 14pt.
If subtitle > 30 chars, then fontsize = 16pt.

How could I write these conditionals?

Many thanks for your help,


Pablo

let tex do the work .. counting is not accurate for this anyway

\starttexdefinition AutoFontSize #1
     \begingroup
         \setbox\scratchbox\hbox{#1}
         \normalexpanded {
             \definedfont[Regular*default at
                 \ifdim\wd\scratchbox>30em 10pt\else
                 \ifdim\wd\scratchbox>25em 12pt\else
                 \ifdim\wd\scratchbox>20em 14pt\else
                 \ifdim\wd\scratchbox>15em 16pt\fi\fi\fi\fi
             ]
         }
         #1
     \endgroup
\stoptexdefinition

\starttext
     \dostepwiserecurse{30}{80}{2}{\AutoFontSize{\dorecurse{#1}{x}}\par}
\stoptext

Many thanks for your reply, Hans.

I don’t need total accuracy with this.

Many thanks for your help again,
