recursive use tag doesn´t work in batik - in Firefox 3.5 it´s ok
hi,
i have an svg file which looks very similar like the one at the end of this
message.
when i load this with Firefox 3.5 everything looks like expected.
But Batik only displays the file in the first use tag. The use tags inside
the first
one are ignored. Can anyone help me out of this ?

It's not a matter of tolerance, it's a matter of conformance to the
specification. ;-)
I created a reduced test case and was about to file an issue in the
Mozilla bug tracker when I noticed this fixed post Firefox 3.5 (tested
with 3.6b1pre and 3.7a1pre nightly builds), so just wait until the
next release or get a nightly build! :-)
I'm attaching the reduced test case anyway, in case anyone wants to
take a look or bumps into the same issue again.
Regards,
Helder

It's awkward to me that it works in Firefox, as far as I know the use
element [1] should be empty and therefore no child content is
expected... :-|

Just remove the nesting from your use elements. Basically, change those
<use>
<use>
<use/>
</use>
</use>
To something like:
<use/>
<use/>
<use/>
Hope this helps,
Helder

As Helder mentions the problem is the nested use elements. If you
check the SVG standard it doesn't allow the use element to contain
other graphical elements (http://www.w3.org/TR/SVG/struct.html#UseElement
):
<!ENTITY % SVG.use.content
"(( %SVG.Description.class; )*, ( %SVG.Animation.class;
%SVG.use.extra.content; )*)"
>
<!ELEMENT %SVG.use.qname; %SVG.use.content; >
So a use element can have desc/title/metadata and animation
elements as children. In fact you will get a validation error
in Batik if you enable using a validating XML parser (and add
appropriate DTD, etc):
The content of element type "use" must match
"(((desc,((title,metadata?)|(metadata,title?))?)|(title,((desc,metadata?)|(metadata,desc?))?)|(metadata,((desc,title?)|(title,desc?))?))?,(animate|set|animateMotion|animateColor|animateTransform)*)".
