You cannot directly limit the results you get by an xpath statement, but you can test for the position of a node:

<xsl:if test="position() &lt; 11">Put your output in here</xsl:if>

with this example you have limited the nodes to 10 (lower than 11).

The second question is not clear to me. Do you mean you have an upload field in a document type defined where you upload a picture for one content node?

Would you specify this question a little bit more,

Thomas

Hmm.  Perhaps not the cleanest way, but

<xsl:for-each select="$currentPage/node">
<xsl:if test="position() &lt; 3">

Do something

</xsl:if>
</xsl:for-each>

This tests to see if the current position is is less than your desired amount before doing something, and is an easy way to limit results.  Does seem to be a waste of cycles though...

As for getting data from document types, this is fundamental.  Try the wiki for more detailed answers, such as  http://our.umbraco.org/wiki/how-tos/working-with-document-types

If the xslt is grabbing data on the document type making up the current page, something like this will bring it out

<xsl:value-of select="$currentPage/data [@alias='Blurb']" />

If not on the current page, have a look at http://umbraco.org/documentation/books/xslt-basics/xpath-axes-and-their-shortcuts

Best thing to do would be to look at how the runway and cws get their data on the page and work from there.

Hi Alan,

Sure it's possible to limit the number of results received from xslt. All you need is to build the xpath query... all depends on what you define as 'limit the number of results'. Can you give a more specific detailed requirement?

For example, let's start with a simple xslt that returns all child nodes for any page in a list (in xslt, that is referred to as the currentPage, which is a variable declared in almost any xslt example you can find in the dropdown when creating an xslt)

<ul><xsl:for-each select="$currentPage/node"><li><xsl:value-of select="@nodeName""/></li></ul>

Above snippet returns a list of child nodes starting from current page. If you'd like to limit the number of items in the list, you could eg.

<ul>
<xsl:for-each select="$currentPage/node [position() &lt; 6]">
<li><xsl:value-of select="@nodeName""/></li>
</ul>

Above snippet will only return the first 5 child nodes. Let's add another restriction. Now, we only want the first 5 child nodes that have a specific value 'MyValue' for a specific property (alias of property = 'propertyAlias'.

<ul>
<xsl:for-each select="$currentPage/node [position() &lt; 6 and string(data [@alias = 'propertyAlias'] = 'MyValue])">
<li><xsl:value-of select="@nodeName""/>
</li>
</ul>

Above snippet will return maximum of 5 child nodes.

Getting the data from the document type (I presume you're after data from the document), is just as easy as using

<xsl:value-of select="@attribute"/> 

or

<xsl:value-of select="data [@alias = 'propertyAlias']"/>

First statement can be used to get the value of an attribute, second example gets the value of a property defined on the document type.

For example, to get the id of the current page you're requesting, you'd write:

<xsl:value-of select="$currentPage/@id"/>

or

<xsl:value-of select="$currentPage/data [@alias = 'propertyAlias']"/>

If you need more help, just shout.

Cheers,
