xxforms:serialize -- unparsable by Google Map API

I am attempting to share data between xforms and the Google Map api.

I have a xforms:textarea that references an instance. This all works
fine if I get the data from a URL to GXml.parse(), but when I pass the
data in a control, it does not parse.

(javascript):

var EventText = ORBEON.xforms.Document.getValue('event-text-ctrl');

var xml = GXml.parse(EventText)

Looking at this with the GMap log, the content is the same, except
that the URL content has broken lines in it and does not have an
XML declaration.

Could it be that GXml.parse() has a line length limit?

Is it possible to add the Saxon indent= and indent-spaces= to
xxforms:serialize?

xforms snippet:

        <!-- Holds the serialized copy of events for javascript processing  -->
        <xforms:instance id="event-text">
        <config xmlns="">
                        <text/>
                </config>
        </xforms:instance>
       
        <xforms:bind nodeset="instance('event-text')"
                xmlns:xs="http://www.w3.org/2001/XMLSchema">
                <xforms:bind nodeset="text" type="xs:string"
                        calculate="xxforms:serialize( instance('events'), 'xml' )"/>
        </xforms:bind>

...

<xforms:group ref="instance('event-text')">
   <xforms:textarea ref="text" id="event-text-ctrl" />
</xforms:group>

It is possible to work around the problem, in my case, by
serializing it as html:

calculate="xxforms:serialize( instance('events'), 'html' )

Cheers,
Hank

Could it be that the parser does not like the XML declaration? If that
is the case, I think it would be better serialize in XML and then
remove the declaration in the generated string.

Hi Alex,

OK, I tried this:

  calculate="substring-after( xxforms:serialize( instance('events'),  
'xml'), '?&gt;' )"/>

Which looks good according to the xforms-inspector -- skips over the
declaration.  However, it does not work.

So, I think the issue is that their parser has a line length
limit, and this could be embedded in the browser (I have
only tested Firefox so far, Google API docs say this function
is dependent on browser support.)

Thanks,
Hank

solution, but I am curious: what is the difference in this case
between the value returned with 'xml' and 'html', besides 'xml'
including an XML declaration?

Alex,

No prob.em...

In html mode, the output wraps to about 40 columns (in the inspector),
there are spaces between elements, e.g.:

<config xmlns:widget="http://www.orbeon.com/oxf/xml/ 
widget"><text><exist:result xmlns:exist="http://exist.sourceforge.net/ 
NS/exist" exist:hits="5419" exist:start="1" exist:count="10">  
<origin> <nass>-1</nass> <evid>14003864</evid> <etype></etype>  
<depdp>-999</depdp> <time>2003-11-15T03:38:19.780Z</time> ....

In xml mode, there are no spaces between elements, and the elements  
are all
"one one line" . e.g.:

<config xmlns:widget="http://www.orbeon.com/oxf/xml/widget"><text><?
xml version="1.0" encoding="UTF-8"?><exist:result xmlns:exist="http://
exist.sourceforge.net/NS/exist" exist:hits="5419" exist:start="1"  
exist:count="10"><origin><nass>-1</nass><evid>14003864</evid><etype/
 ><depdp>-999</depdp><time>2003-11-15T03:38:19.780Z</time><review>-</
review><msid>-1</msid><lat>33.467</lat><auth>cit_14003864</
auth><dtype>-</dtype><ms>-
......

not sure what that will look like, email client is breaking it up
on '-' characters.

Thanks,
Hank

I see. And I wouldn't think that this should make a difference. Like
you said, this looks like a "special requirement" (or bug?) in the
Google Maps API.
