Multiselect metadata propert in xml form

Question

Hi,
I have created an xml form to create news items for our company. I would like to add a custom metadata property that i have created that is multiselect.
Eg I have created a multi valued property named “sls_region” with allowed values All, America, Europe. I have assigned this property in custom parameter section of Editxsl file of xml form.
I have created a filter with “sls_region “property with all allowed values for property available in dropdown.
While uploading news whatever value is selected in dropdown of filter gets assigned to custom property of the form.
To make it more clear
sls_region has value All, America, Europe
If in filter dropdown America is selected …..custom property has value set as America
If in filter dropdown Europe is selected …..Custom property has value set as Europe
If in filter dropdown All is selected …..Custom property has value set as All
This is working fine .Code which I am using for this is
<xsl:param name="ext_mars:sls_region" />(Defined in custom parameters section)
<input size="30" type="hidden"> 
<xsl:attribute name="name">wcmprop.mars:sls_region</xsl:attribute>
<xsl:if test="$ext_mars:sls_region=' '">
                 <xsl:attribute name="value" /> </xsl:attribute>
            </xsl:if>
             <xsl:if test="$ext_mars:sls_region!=' '">
               <xsl:attribute name="value">
<xsl:value-of select="$ext_mars:sls_region"/></xsl:attribute>
            </xsl:if>
</input>
But I need to change functionality like when user select All in dropdown of filter, all available values for that custom property get sets in form.
If in filter dropdown All is selected …..Custom property should have value set as All, America, Europe
Please guide me how to modify above code to achieve this.

Thanks for responding
sls_region is a multi value  property with values ALL , America, Europe.
My current code which is working fine is like …whatever I select in my filter (a sender iview, custom developed component with multi value properties sls_region appearing as dropdown) get passed to receiver iview (basic search iview with a modified epcf receiver as collection renderer).
Receiver iview is used for both uploading news and searching news. To upload news I am using xml form. I have modified edit xsl of form ….by adding code as mentioned above in my thread in detail
So if in filter if I select America as region …..Uploaded news will have sls_region property set to America.
If All is selected uploaded news has sls_region set to All.
Code mentioned in my thread is working fine but now I need to modify it like ….
If I Select All in filter...Uploaded news should be set with all allowed values of  sls_region property i.e.  All, America, Europe.
To make it more clear if you look at my code above I want to add logic like
if (test="$ext_mars:sls_region=' '")
<xsl:attribute name="value" /> </xsl:attribute>
Else {
If (test="$ext_mars:sls_region = ‘All’)
Value of select = “All” and “America” and “Europe” means news  get uploaded with            available values of  sls_region
Else
<xsl:value-of select="$ext_mars:sls_region"/></xsl:attribute> only with what is selected in filter either America or Europe.
I want to set all allowed values of property sls_region in case when ‘”All” is selected in filter.
Hope this will help you to have a clear understanding of my problem.
