RE: Arrays in xforms

standard xpath allows sequences, you can split a string using xpath functions such as tokenize()

As mentioned, XPath 2.0 has sequences, and you can split strings with
tokenize(). The only issue is that xforms:repeat only iterates over
nodes, and it can't iterate over strings. So you can't just write
<xforms:repeat nodeset="tokenize(...)">. Instead, you will have to:

* create nodes into an instance, e.g. using xforms:insert
* then point xforms:repeat to those nodes

Hello Ryan,

<xforms:output value="string-join(for $i in

tokenize(instance('cityvalues')/city, ',') return

string($i), '|')">

Can I set these values in repeat..?Bcz I have to have different functionality for each and every string.

Prameela.

What do you mean by "set these values in repeat"?

RE: Re: RE: RE: RE: Arrays in xforms

I.e. can I use the tokenized values in repeat similar to instance parsing?

For now, I used a JavaScript function to split and display those in
xform.But it would be nice if we do it with xform itself.

If you have a sequence of strings, and want to iterate with an
<xforms:repeat> on it, assuming the sequence in in $seq, you can do:

<xforms:repeat nodeset="for $s in $seq return xxforms:element('text',
$s)">

This gets your around the limitation of <xforms:repeat> wanting nodes
by creating an element for each string in your sequence.

RE: Re: RE: Re: RE: RE: RE: Arrays in xforms

Alex,

Thank you for your response.

I tried with the following code where instance('cityvalues')/city has set of
strings with delimiter ','

<xforms:repeat nodeset="for $v in tokenize(instance('cityvalues')/city,',')
return xxforms:element('text', $v)">
<xforms:variable name="val" ref="."/>
<xforms:setvalue ref="instance('listvalues')/value1" value="."/>
<a
href="http://localhost:8080/web/guest/home?p_p_id=organizeby_WAR_organizeby&
amp;p_p_lifecycle=0&p_p_state=normal&p_p_mode=view&p_p_col_id=co
lumn-1&p_p_col_count=1&_organizeby_WAR_organizeby_eventid={$val}.xml
&_organizeby_WAR_organizeby_oxf.path=%2Fportlet-welcome%2Fshowdetails.xh
tml"><xforms:output ref="."/></a> </xforms:repeat>

It gives no errors but when I try to print variable value, it gives
empty.Even no value is set into the instance.
If I use this <xforms:output ref="."/> in repeat there is no problem, iam
able to print it. But I need it in anchor tag.

I think I can manage it using substring function as repeat function works.
If there is a solution other than with substring , please do send.

Prameela.

<xforms:variable name="val" ref="."/>

The <xforms:setvalue> above, inside the <xforms:repeat> isn't doing anything. Actions must listen to an event, and they will run when that event is dispatched to their parent element. Even if your code is working, you might want to remove that <xforms:setvalue> just to prevent people reading this code from getting confused.
