Probably I am missing something...
Can there be an element with two attributes with same namespace uri
and localName
i.e.

<sampleElement ns:attr="First Value" ns:attr="Different value for same
namespace(ns) and same localname (attr)">
</sampleElement>

Is the above a valid piece of XML?


this is invalid XML w/ Namespaces - it is possible to have
<foo n:a='x' m:b='y' xmlns:n="k" xmlns:m="k" /> in pure XML 1.0 but it is invalid in XML 1.0 w/ Namespaces

just test it with XML Parser (make sure namespaces are enabled/disabled)

alek

If yes, what should one return when queried for value of ns:attr attribute.

Thank you

Hi Jaya,

I also expected the same reply :) :).

See my comments below.



Hi Eran!
I predicted this reply :-)
Then, at least the names should be changed. Otherwise
readability&usability of code is at stake.
We can have
public Iterator getAttributesNS(OMNamespace ns) to do what you wanted to
do.

And when syntactically only one attribute with a given qname
(namespace + localname) can exist in an element, calling a
getFirstAttribute(qname) wouldn't look nice.


You can construct a QName *only* giving the localName. So if I call
getAttributes(new QName("localName")), you will get all the attributes with
the same name, but with different namespace in a particular element.
Well, at the sametime I know that this is a rare situation ;).

Anyway, I like to have a method to get all the attributes with a given
namespace, with a given local name, with a give namespace uri. So the
intention behind me providing that method was to answer that.

Any suggestions for a different signature to cater the above problem ??



Can its signature be
changed to
public OMAttribute getAttribute(QName qname)


Nope this will return only the first matching one *only*. What is there are
more than one in a particular element ??

So for this purpose I have put

+ getFirstAttribute(QName):OMAttribute

If the suggested changes sound agreeable can you do them at your
earliest convenience.

Thank you

Nope.

public OMAttribute getFirstAttribute(QName qname) throws OMException


will


fullfil that thing.

But the public Iterator getAttributes(QName qname) method will do


something


different.

Well from this method what I expected was, one can just get give the
namespace and get all the attributes with that same namespace, like


that.


Well, I think I implemented this, but its now not in the source.

Let me look at this.

You are quite right, Jaya.  That should get fixed.

Hi!
I see the following method signature in OMElement.java
 public Iterator getAttributes(QName qname);

Should it not be something like
 public OMAttribute getAttribute(QName qname);

Can there be a list of (more than one) attributes with the same


qname


in an element? Am I mistaken somewhere?

Thank you
Jaya
