Re: XForms: Bind value of attribute?

Yes, you can use ref to bind a UI control to an attribute.  So instead of 
using a value element in your data, you could use a value attribute. Then, 
the refs on your select1 would say ref="@value" instead of ref="value".

XForms: Bind value of attribute?







My scenario is like this, I have a model:
<data>
<Animals>
<Cat appearance="full" name="Cat 1" ><value>Red</value></Cat>
<Cat appearance="compact" name="Cat 2"><value>Green</value></Cat>
<Cat appearance="minimal" name="Cat 3"><value>Brown</value></Cat>
</Animals>
</data>


Now I want to display the cat colors like this:
I want full select1 for Cat1 (appearance = full), compact select1 for
Cat 2, and minimal select1 for Cat 3. Does xForms support like
xsl:attribute element or something? We can ref any element, but can we
do the same for attribute? I am currently doing like this, which works,
but I was wondering if there was a better way.

<xf:repeat nodeset="Animals/Cat">
<!-Show full -->
<xf:group nodeset="current()[@apprearance='full']">
<xf:select1 ref="value" appearance="full">
                 <xf:label ref="../@name"/>
<xf:itemset nodeset="/data/Colors/data">
                   <xf:label ref="."/>
                   <xf:value ref="."/>
                 </xf:itemset>
</xf:select1>
</xf:group>

<!-Show Minimal -->
<xf:group nodeset="current()[@apprearance='compact']">
<xf:select1 ref="value" appearance="compact">
                 <xf:label ref="../@name"/>
<xf:itemset nodeset="/data/Colors/data">
                   <xf:label ref="."/>
                   <xf:value ref="."/>
                 </xf:itemset>
</xf:select1>
</xf:group>

<!-Show Compact -->
<xf:group nodeset="current()[@apprearance='compact']">
<xf:select1 ref="value" appearance="compact">
                 <xf:label ref="../@name"/>
<xf:itemset nodeset="/data/Colors/data">
                   <xf:label ref="."/>
                   <xf:value ref="."/>
                 </xf:itemset>
</xf:select1>
</xf:group>

</xf:repeat>
