Hi Mike,
thanks for the effort - this recreates the issue for me and is certainly a bug, as you said. I'll have a look at it.

Hi
A bit laborious to recreate but .. here goes:
basexclient ... insert nodes then run:
xquery /
<a> <b/> <d> <e test="here"/> </d> </a> Query executed in 0.2 ms.
No problem - I see what I expect. Then run this:
xquery insert node <c>{http:send-request( <http method='get'
status-only='false'/>, "http://internet.org.uk" ) }</c> into /a
Query executed in 502.05 ms.
xquery /
<a> <b/> <d> <e test="here"/> </d> <c> <http:response xmlns:http="http://expath.org/ns/http-client" status="200" message="OK"> ... ... SNIPPED THE MIDDLE BODY OUT AS IT'S THE HTML RETURNED FROM THE SITE ... </c> </a> Query executed in 1.7 ms.
xquery insert node <f/> into /a/d
Query executed in 1.34 ms.
xquery /
<a> <b/> <d> <e test="here"/> <f/> </d> <c> <http:response xmlns:http="http://expath.org/ns/http-client" status="200" message="OK"> <http:header name="Expires" value="Mon, 26 Jul 1997 05:00:00 GMT"/> <http:header name="Last-Modified" value="Mon, 02 Apr 2012 15:47:39 GMT"/> <http:header name="Set-Cookie" value="mosvisitor=1"/> ... ... ... </c> </a> Query executed in 1.72 ms.
xquery delete node /a/d
Query executed in 1.54 ms.
xquery insert node <d/> into /a
Query executed in 1.56 ms.
xquery insert node <h test='hello'><i/></h> into /a/d
Query executed in 1.76 ms.
xquery /

So, item 'h' suddenly gains a namespace.
Sorry it's a bit convoluted to recreate, but it gets the results I see.
Cheers Mike

Ok, I see the problem, unfortunately I still can't replicate the issue with our current repository version. I started with a document like this:
*<a> <b/> </a>*
and used the following insert statements:
*insert node <c xmlns='newns'/> into /a*
and afterwards ...
*insert node <d/> into /a*
Still, there's no namespace linked to <d/>. Can you replicate the issue with this example or change it in a way that it replicates it?

Yep - this definitely causes problems. Insert a node that includes a namespace and all subsequent nodes end up with a namespace inserted. So ... I think this presents a bug:
<root> <nodes without namespace/> <new nodes work well/> </root>
vs.
<root> <nodes without namespace/> <node with namespace/> <new nodes automatically get spurious namespace/> </root>
Hope that helps - not sure how best to fix or work around this at the moment though.

Hi Lukas/Christian
It's the built-in one as far as I'm aware - I haven't done anything special to add or remove any parsers. But that's sent me down a path where I can get it reliably.
It appears that it's coming from another query that I run to check the state of a web-site. As soon as I run the following query, BaseX inserts the namespace for every inserted node thereafter:
insert node <webpage url="http://internet.org.uk" name="primaryDomain">{ http:send-request( <http:request method='get' status-only='false'/>, "http://internet.org.uk" )} </webpage> into doc($DB)/root/webpages
As soon as I have any node after the above query has run, BaseX inserts the namespace. Otherwise it doesn't. If I delete all the nodes within the <webpage> tags, things return to normal again.
Is there an easy way to do the above without adding any namesakes (I don't actually want to include them from the web query either)? This should solve the problem.
Cheers Mike

Hi Mike,
Leo just came up with another idea: Which kind of parser are you using in BaseX?
If you use the HTML parser for parsing XML, the strange behaviour you came across might indeed be expected ... If you're not sure which parser you are using, just take a look at our documentation [1].

It's mad - I don't add a namespace, the source document is a text file without a namespace - and the log shows that I don't add it ... but it appears. No idea why.

So it seems that the once added namespace is propagated to other documents? I believe there must be at least one document with the mentioned namespace in your database; otherwise I can't explain where it should come from (afaik, the string "http://www.w3.org/1999/xhtml" isn't hard-coded anywhere in the project)...

The initial XML file contains the initial nodes with which to
populate the XML database (root plus numerous other nodes). The PHP code inserts additional nodes as it runs. For every node I add, I create an audit entry to allow me to determine who and how the database built over time.
initialdb.xml contains, therefore:
<root> <auditlog/> </root>
You're right - ignore 'test' - I meant WYP in the database - as in
drop database WYP create database WYP test/initialdb.xml
Apologies for any confusion caused.
It's really weird - I can't get this to fail consistently - but when
it starts inserting the namespace attribute, it then continues to do so.

The database you're creating seems to be called "test"; what's
"initialdb.xml"?

OK 0.05 msThe log info implies you're having "root" and "auditlog" nodes, and the addressed database is called "WYP", is that right? Could you pass us on the missing snippets?
