RE: XUpdate and the '&' character

[Jeroen Breedveld]

Hi,

Not using & shouldn't work at all because then the XML document
isn't wellformed. 
I did some tests on the online XUpdate-demo on
http://www.x-hive.com/xupdate

this: (note & before http://myserver ...)
 
<xu:modifications version="1.0" xmlns:xu="http://www.xmldb.org/xupdate";>
  <xu:update
select="/addresses/address/town">&amp;http://myserver.cgi?parameter1=min
eparameter2=0</xu:update>
</xu:modifications>

results in this:

<?xml version="1.0"?>

<addresses>
  <address name="Andreas">
    <town>&</town>
  </address>
  <address name="Lars">
    <town>&</town>
  </address>
</addresses>

It appears that when a text-node contains character entities, SAX breaks
the string up in to pieces that for some reason aren't all processed by
XUpdate, only the first part is. If this is true it is a bug in XUpdate.


greetings,

Jeroen

 | Hi!
 | 
 | I_m attempting to use XUpdate to update a node in our 
 | Xindice database and I
 | _m having the following problem:
 | 
 | I_m using the following XUpdate:
 | 
 | <xu:modifications version="1.0" 
 | xmlns:xu="http://www.xmldb.org/xupdate";>
 |              <xu:update
 | select="//RootNode/TestNode">http://myserver.cgi?parameter1=m
 | ine&parameter2=
 | 0</xu:update>
 | </xu:modifications>
 | 
 | to update the contents of the node TestNode.  When I query 
 | the database to
 | see whether the update has been successful I find that the 
 | node text has
 | been truncated from  the _&_  onwards i.e. it has been updated to
 | http://myserver.cgi?parameter1=mine 
<http://myserver.cgi/?parameter1=mine>
and not http://myserver.cgi?parameter1=mine&parameter2=0
<http://myserver.cgi/?parameter1=mine&parameter2=0>  as expected.

I_ve tried replacing the _&_ with _&amp;_ in the XUpdate query to see if
that makes any difference_and it doesn_t!

Can anybody suggest a way that I can update this node successfully?

Thanks in advance,
