A simple issue that pops up when using
XML to represent object-oriented languages
is the mismatch between fields and attributes.
If a field has structure, it shouldn't be
an attribute. But when the expression is
simply repeatability (ie, the attribute
contains an array of string values), the
messy problem of spaces pops back out.
To me these are ugly hacks:
URL='"me1.jpg" "me2.png"' and
URL='"me.jpg""me2.jpg"'
and dicey because:
o they are vulnerable to authoring errors,
so weakening the XML document where it is
suppose to be strong: parse and go.
o they are vulnerable to the machinations
of XML-like systems such as the SOAP
processor which does nothing with the
entity declaration.
But considering that filenames can have
spaces in them in both MS and Unix operating
systems, other than stuffing %20 in the strings,
that is a likely solution.
Other than
<url>me1.jpg</url>
<url>me2.jpg</url>
what are better solutions?
