Looping through all values of a propertyTypePickerMultiple in XSLT

I'm using a propertyTypePickerMultiple as Macro Paramater,
but how do I split all these properties so that I can get the values of these properties?

Hi Bram

I can't remember xich character that seperates the values, but maybe you could something like this:
```
<xsl:variable name="ids" select="concat(macro/propertyTypePickerMultiple,',')"/>

<xsl:variable name="split" select="umbraco.library:Split($ids, ',')"/>
```
I used something like this earlier, when I used the multipleContentPicker, where the id's where seperated by commas. You could try to write out the $split to see how the values are split up in some fine XML.

Thanks Kim,

How do I loop through the items of 'split now?
```
<xsl:for-each select="$split">
  <xsl:value-of select="$split"/><br />
</xsl:for-each>
```
this returns just the whole string all the items

try:
```
<xsl:for-each select="$split/value">
```

Try this:
```
<xsl:template match="/">  
  <xsl:variable name="ids" select="concat(macro/propertyTypePickerMultiple,',')"/>

  <xsl:variable name="split" select="umbraco.library:Split($ids, ',')"/>
  <xsl:apply-templates select="$split//value" />
</xsl:template>


<xsl:template match="value">
  <xsl:variable name="itm" select="umbraco.library:GetXmlNodeById(.)"/>
  ...
  ...
</xsl:template>
```
In the new template, we can make a new variable called $itm. This variable should contain the XML from the node with the right id. And the template will be looped for every id in your $split. A good idea is to make a textarea and print out the $itm, to check that it contains the right XML. Like this:
```
<textarea>
  <xsl:copy-of select="$itm" />
</textarea>
```
This textarea shall of course be placed inside the <xsl:template match="value">

Does it make sense?

nice bl_ndp_lot but that return only the first item.

It use thes properties:

the properties: siteDescription, siteName, pageAlt, pageTitle

and I get this response:

- siteDescription
- siteDescription
- siteDescription
- siteDescription
- siteDescription

with this XSLT
```
the properties: <xsl:value-of select="$properties"/><br />
<xsl:variable name="ids" select="concat(macro/properties,',')"/>
<xsl:variable name="split" select="umbraco.library:Split($ids, ',')"/>

<xsl:for-each select="$split/value">
   - <xsl:value-of select="$split/value"/><br />
</xsl:for-each>
```

except of the fact that I return now 5 value (the for values I selected + one empty one) the solution of Kim works

Sounds great Bram.

Actually you can use another selection in your apply-templates, to make sure that you're not looping trhough the empty <value>-tag at the end. Try this one instead:
```
<xsl:apply-templates select="$split//value[./text() != '' and umbraco.library:GetXmlNodeById(./text())/@nodeName != '']"/>
```
Your other template should still match "value", so no change there.

Glad I could help :)
