issue with lpath containing a hyphen

issue with lpath containing a hyphen

[Pablo Rodriguez]

Hans,

I have the following sample:

    \startbuffer[demo]
    <doc>
        <div id="a-b">
            is it working
        </div>
    </doc>
    \stopbuffer

    \startxmlsetups xml:initialize
        \xmlsetsetup{#1}{doc}{xml:*}
        \xmlsetsetup{#1}
            {div[@id='a\letterpercent-b']}
            {xml:a:b}
    \stopxmlsetups

    \xmlregistersetup{xml:initialize}

    \startxmlsetups xml:doc
        \xmlflush{#1}
    \stopxmlsetups

    \startxmlsetups xml:a:b
        \input knuth
    \stopxmlsetups

    \starttext
         \xmlprocessbuffer{main}{demo}{}
    \stoptext

The only way to get the Knuth in the quote is to remove "\letterpercent"
in the lpath.

I guess I must be doing something wrong in this sample. In my real
document, I cannot simply remove it, I get an error.

As a general consideration, houw about making not mandatory to escape
characters in lpaths? This would ease the traslation from XML code to
lpaths.

Many thanks for your help,

Pablo

so why do you use the \letterpercent then

It was a minimal sample taken from from a larger project.

I have just discovered that the compilation error has nothing to do with
the hyphen.

Then I have the question about lpaths: do I have to remove all instances
of \letterpercent?

They seem to work fine, but I had the impression that \letterpercent was
mandatory and now I don’t know whether it is allowed or simply forbidden.

Many thanks for your help,

Pablo

afaiks they are not needed unless you use lua function that use find or 
gsub
