Element[] to QName to topic?

[Jan Torben Heuer-4]

Hi,

How can I parse topics that are supplied via soap? I want to add them later
with NotificationProducer#addTopic(QName);

The xml-code may look like:
<wsbn:Topic
dialect="http://docs.oasis-open.org/wsn/t-1/TopicExpression/Simple"
xmlns:tsas="http://www.opengis.net/ses/1.0.0/">
        <tsas:Measurements>mytopic</tsas:Measurements>
</wsbn:Topic>

But I'm not sure how else the topic can be provided.
Is there already topic-parsing-code in muse that I can reuse?


Thanks,

Jan

Hi Jan,

The XmlUtils.getQName / getQNameFromChild functions can retrieve QNames for you.  These search up the path to collect the namespaces mentioned by the QNames.  Note these are QNames in the xsd fashion i.e. prefix:localName and the prefix -> namespace mapping must be in a parent element.

cheers,
Chris

The method signature is: XmlUtils.getQName(Element) - however the topic is
parsed as DefferedTextImpl which is a node but not an Element. Did I miss
something? My topic looks like:

<wsbn:Topic
dialect="http://docs.oasis-open.org/wsn/t-1/TopicExpression/Simple"
xmlns:tsas="http://www.opengis.net/sas/1.0.0/">
                                tsas:Measurements
</wsbn:Topic>

is that correct?

Hi Jan,

the wsbn:Topic element is the one that you pass in.  It should then get the QName from the element fully.  Note that this only helps with simple topic expressions not the full expression syntax (which can't return a single QName).  FYI Muse doesn't support the full expression syntax (nested namespaces etc).

cheers,
Chris
