Converting a string sequence to elements

<result>A B C</result>

<foo>
    <bar>A</bar>
    <bar>B</bar>
    <bar>C</bar>
</foo>

Jim,

I don't understand the answer, which was, "select/itemset/copy will work." Can someone tell me what that means, please?

i think it's a kind of "XPath shortcut" to denote a certain method to include the itemset details for the select. The following message shows a combination of xforms:item (as initial entry), xforms:itemset to reference a set of elements that contain the different entry/value pairs, and a xforms:copy to "import" the entry/value children of that itemset.

http://www.nabble.com/xforms%3Acopy-workaround-p15512467.html

This is "select/itemset/copy". select/itemset/value is represented by the example at the end of that doc chapter:

http://www.orbeon.com/ops/doc/reference-xforms-ng#xforms-controls-list

And select/item/value means to put the selection list items directly into the xforms:select as xforms:item.

But i suppose you will need to use the delete/insert workaround as in the xforms-copy sandbox example

http://www.orbeon.com/ops/xforms-sandbox/sample/xforms-copy

Using an xforms:select places all the selected strings into one XML element, separated by spaces. Is there some way to iterate through those strings and surround each one with an XML element?

For example, if the xforms:select puts the strings A, B, and C into

<result>A B C</result>

how can I convert that into the following?

<foo>
    <bar>A</bar>
    <bar>B</bar>
    <bar>C</bar>
</foo>

Thanks,
-Jim

If i understood it correctly, the solutions proposed in the mentioned thread don't work with the string output. Both work with the selected elements.

Your way might be better, but I just don't understand what you're saying I should do with a multiple selection to get the effect I want. Could you give me an example maybe?

If you really want to work with the concatenated string, there are different ways. You could split it up using JavaScript or XSLT and process the results. A quite elegant way might be to use a nightly build and apply the xxforms:iterate function [1] after tokenizing the string. Something like

<xforms:action
        ev:event="DOMFocusOut"
        xxforms:iterate="tokenize(/nodeWithSelection, ' ')">
    <xforms:insert
        context="instance('main-instance')"
        nodeset="book"
        origin="instance('template-instance')"/>
    <xforms:setvalue
        ref="instance('main-instance')/book[last()]/title"
        value="context()"/>
    <xforms:setvalue
        ref="instance('main-instance')/book[last()]/author"
        value="context()/following-sibling::author"/>
</xforms:action>

but i don't know whether this will work.

That looks interesting. Just yesterday I needed a way to iterate through a set of strings and use each of those strings to form a hyperlink, but I wasn't able to get it working. I finally had to use a repeat, which gives the first link an undesirable orange-ish background. I didn't have an event that triggered the action, so maybe that was the problem. Is it possible to iterate without a triggering event?

Thanks,
