Name-value pairs in xml root tag
Hi there,
Is it possible to use JAXP API to retrieve schema and prefix name-value
pairs in the root element tag? for example,
<?xml version="1.0" encoding="UTF-8"?>
<test:inputParameters xsi:type="test:ArrayOfParameterType"
xmlns="http://rules.bellaliant.icn/testing"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:cbebi-v1-5="http://ossj.org/xml/Common-CBEBi/v1-5"
xmlns:cbecore-v1-5="http://ossj.org/xml/Common-CBECore/v1-5"
xmlns:cbeproduct-v1-5="http://ossj.org/xml/Common-CBEProduct/v1-5"
xmlns:cbeservice-v1-5="http://ossj.org/xml/Common-CBEService/v1-5"
xmlns:co-v1-5="http://ossj.org/xml/Common/v1-5"
xmlns:om-v1-0="http://ossj.org/xml/OrderManagement/v1-0"
xmlns:test="http://rules.aliant.ca/testing"
/>
I can get _xsi:type="test:ArrayOfParameterType"_ from the input parameter
org.xml.sax.Attributes passed on to startElement() method. But can I get the
rest of the n-v pairs in any of the PSVIProvider or TypeInfoProvider APIs?
(I did a quick search, but could not find one)
thanks,
David

Um... why not? The startPrefixMapping() calls come first. You should always
have all the information you need to do prefix -> uri mapping on any
startElement()..

There are plenty of samples, FAQs and articles which show how to use or
talk about how to use these things in isolation, but you'd probably have to
connect the dots yourself.

Hi Michael,
I thought this would solve my problem. But I run into an order issue.
What I want is to be able to match from a uri to its prefix while parsing
through an xml. It seems startPrefixMapping() is paired with startElement().
So if there is a xsi:type attribute of the element pointing to a new type
yet been parsed, I won't be able to find the prefix in the uri -> prefix
hashtable I have been keep tracking.
It seems to me that a SAX parser may not work for what I want. Is there a
sample using a DOM parser to traverse a DOM tree and still be able to use
JAXP to get TypeInfo and ElementPSVI?
thanks a lot,
David

Namespace declarations are normally reported in SAX through the
startPrefixMapping() [1] and endPrefixMapping() [2] callbacks.

(java.lang.String,%20java.lang.String)
[2]

(java.lang.String)

I used the sample handler in jaxp.TypeInfoWriter. Looks like it should be
straight forward; I must have overlooked sth ... Can you just quickly point
out which object I should use?
thanks a lot,

Those are all namespace declarations. If you register the right SAX
handler, you should have no trouble seeing them.
