issue with css selector in lpath

issue with css selector in lpath

[Pablo Rodriguez]

Dear list,

I have the following code:

    \xmlsetsetup{\xmldocument}
        {{header, #header}}
        {xml:titlepage}

I guess this is right, but I get the following compilation error:

tex error       > tex error on line 303 in file pandoc-xhtml.tex: !
Illegal parameter number in definition of \14>:xml:pandoc

<to be read again>
h
<argument> ...en:h1}\xmlsetsetup {\xmldocument }{{header, ##h

eader}}{xml:titlepage}\xml...
\syst_setups_start_xml_indeed ...1\expandafter {#3
                                                  }
l.303 \stopxmlsetups

If I replace the code above with the following one, everything compiles
fine:

    \xmlsetsetup{\xmldocument}
        {{header, [id="header"]}}
        {xml:titlepage}

Am I missing something, or what am I doing wrong here?

Many thanks for your help,

Pablo

I think it's the "#header" without the name of an element before.
Try specifying an element you find in your document (i.e. "{{header,
tag#header}}"), just to see if it compiles.

If it compiles, it's likely you found a bug.

No, it doesn’t compile.

But {header, #header} shouldn’t be a problem, accorrding to
http://pragma-ade.com/general/manuals/xml-mkiv.pdf#page=34.

If this isn’t a bug, I wonder what I’m doing wrong.

Many thanks for your reply,

Pablo

Could you send a minimal (not) working example?

The error you get says that #header is read as a macro parameter, but
the "#" is not followed by a number, so the error.
Why "#header" is interpreted as a parameter? It smells like the "#" is
being parsed in a context with the wrong catcodes.

I would investigate the first (\xmldocument) and the third argument
(your xml:titlepage setup).

For the first one, I've always used the form:
\xmlsetsetup{#1}{{header, #header}}{xml:titlepage}

I'm reading from xml-mkiv.pdf, at page 19, that "The macro \xmldocument
expands to the current document id. There is also \xmlself which
expands to the current node number (#1 in setups)."

Could you modify your setup to use that form ("#1" i mean) and see if
it works?

Best wishes,
Massi

Here you have it:

    \startbuffer[demo]
    <doc>
        <header>
            <p>Document Title</p>
            <p>Text from paragraph.</p>
        </header>
        <div id="header">
            <p>Document Title</p>
            <p>Text from paragraph.</p>
        </div>
        <div class="header">
            <p>Document Title</p>
            <p>Text from paragraph.</p>
        </div>
    </doc>
    \stopbuffer

    \startxmlsetups xml:initialize
         \xmlsetsetup{#1}{doc|p}{xml:*}
         \xmlsetsetup{#1}{{header}}{xml:header}
         \xmlsetsetup{#1}{{.header}}{xml:header:class}
         %~ \xmlsetsetup{#1}{{#header}}{xml:header:id}
         \xmlsetsetup{#1}{{id="header"}}{xml:header:id}
    \stopxmlsetups

    \xmlregistersetup{xml:initialize}

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

    \startxmlsetups xml:header
       \startalign[left]\xmlflush{#1}\stopalign
    \stopxmlsetups

    \startxmlsetups xml:header:class
       \start\em\xmlflush{#1}\stop
    \stopxmlsetups

    \startxmlsetups xml:header:id
       \startalign[right]\xmlflush{#1}\stopalign
    \stopxmlsetups

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

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

.header works fine, it is only #header that breaks compiliation.

I hope Hans can fix it (or explain what I’m doing wrong).

Many thanks for your help,

Pablo

There's nothing to fix, as mentioned already # is kind of special in 
tex, so you need to escape it:

\xmlsetsetup{#1}{{\letterhash header}}{xml:header:id}

The same is true for % : \letterpercent.

Many thanks for your reply, Hans.

I got it now. xml-mkiv.pdf contains not escaped samples of css
identifier selectors, which contributes to the confusion.

Since the selector is basic in css (and escaping it gives a very weird
css), could you consider that it might not be required to escape # as
css selector?

(I would ask the same also for %, but I have never seen it in css.)

Many thanks for your help,

Pablo

then #1 would not work
