concatenating attribute values in XML

concatenating attribute values in XML

[Pablo Rodriguez]

Dear list,

I have the following definition:

    \startxmlsetups xml:image:sidebyside
        \blank\startalign[center]
            \dontleavehmode
            \externalfigure[\xmlattribute{#1}{./p/img}{src}]
                [width=.5\textwidth]
            %~ \xmlconcat{#1}{./p/img}{ }
        \stopalign\blank
    \stopxmlsetups

How can I define the external figure so I concatenate the image file
names in the code above?

I mean, \xmlconcat is great, but I don’t see how I could make it work to
get values from the src attribute.

Many thanks for your help,

Pablo

why do you want to pass multiple names to \externalfigure

Many thanks for your reply, Hans.

My code was wrong, I need two external figures, not one. I only get the
same image repeated twice. I don’t know how to solve it.

This is what I have in the XML file:

    <div class="sidebyside">
        <p><img src="img/first-image.png" />
           <img src="img/second-image.png" /></p>
    </div>

This is what I tried in the environment file:

    \startxmlsetups xml:sidebyside
        \blank\startalign[center]
            \dontleavehmode
            \externalfigure[\xmlattribute{#1}{./p/img}{src}]
                [width=.5\textwidth]
            \externalfigure[\xmlattribute{#1}{./p/img}{src}]
                [width=.5\textwidth]
        \stopalign\blank
    \stopxmlsetups

And this is what I need in pure ConTeXt:

    \blank\startalign[center]
        \dontleavehmode
        \externalfigure[img/first-image.png][width=.5\textwidth]
        \externalfigure[img/second-image.png][width=.5\textwidth]
    \stopalign\blank

How could I achieve the second? (Concatenation is the only thing that
comes to my mind.)

Many thanks for your help,

Pablo

Sorry, Hans. Today I realize I was saying nonsense.

I solved it with:

    \xmlsetsetup{\xmldocument}
        {[contains(@class,'sidebyside')]/p}
        {xml:sidebyside}

    \xmlsetsetup{\xmldocument}
        {[contains(@class,'sidebyside')]/p/img}
        {xml:image:sidebyside}

    \startxmlsetups xml:sidebyside
        \blank\startalign[center]
            \dontleavehmode
            \xmlflush{#1}
        \stopalign\blank
    \stopxmlsetups

    \startxmlsetups xml:image:sidebyside
        \externalfigure[\xmlatt{#1}{src}][width=.495\textwidth]
    \stopxmlsetups

Sorry for the noise,

Pablo
