Re: [Exist-open] Strange behaviour

[Jean-Christophe K. <jc...@ba...>]

Thanks for your answer.
You're right, I work with Cocoon.

If I try this :

http://localhost:8088/db/shakespeare/plays?_query=3D(::pragma%20exist:ser=
ialize%20omit-xml-declaration=3Dno::)for%20$doc%20in%20//PLAY[contains(TI=
TLE,'Tragedy')]%20return%20%3Ctest%3E{$doc/TITLE}%3C/test%3E

I have 3 results that are not displayed as usual in my FF browser (I=20
have a blank screen but source code is the following ) :

<?xml version=3D"1.0" encoding=3D"UTF-8"?>
<exist:result xmlns:exist=3D"http://exist.sourceforge.net/NS/exist"=20
exist:hits=3D"3" exist:start=3D"1" exist:count=3D"3"><test><TITLE>The Tra=
gedy=20
of Romeo and Juliet</TITLE></test><test><TITLE>The Tragedy of Hamlet,=20
Prince of Denmark</TITLE></test><test><TITLE>The Tragedy of=20
Macbeth</TITLE></test></exist:result>

If I try to read this with cocoon with the following :

<map:match pattern=3D"getTest">
     <map:generate=20
src=3D"http://localhost:8088/db/shakespeare/plays?_query=3D(::pragma%20ex=
ist:serialize%20omit-xml-declaration=3Dno::)for%20$doc%20in%20//PLAY[cont=
ains(TITLE,'Tragedy')]%20return%20%3Ctest%3E%3Cone%3E{$doc/TITLE}%3C/one%=
3E%3C/test%3E"/>
         <!--map:transform src=3D"stylesheets/identity.xsl"/-->=20

     <map:serialize type=3D"xml"/>
</map:match>

Then the content disappears. I obtain a blank screen with the following=20
source code :

<?xml version=3D"1.0" encoding=3D"UTF-8"?>
<exist:result xmlns:exist=3D"http://exist.sourceforge.net/NS/exist"=20
exist:hits=3D"3" exist:start=3D"1"=20
exist:count=3D"3"><test/><test/><test/></exist:result>

I can't say if it's Exist or Cocoon's fault.

For example, if I write $adoc instead of $doc inside the braces, no=20
error happens. Very strange.

Any ideas ?
