I have used two syntax to access the another nodes children in umbraco 4.0.3 on my current page.

Here is the two syntax:-

1st one is:-

<xsl:variable name="First" select="umbraco.library:GetXmlNodeById(1234)" />

2nd one is:-

<xsl:variable name="Second" select="count($currentPage/ancestor-or-self::node/descendant-or-self::node[@nodeTypeAlias = 'test1'] )"/>

And output of these two variables is same:-

<xsl:value-of select="$First "/>

<xsl:value-of select="$Second "/>

In my example output is:

8

8

And then I used these variables value in function getRandom($First ) , getRandom($Second ) 

<xsl:variable name="randomPositions" select="random:getRandom($First)" />

<xsl:variable name="randomPositions1" select="random:getRandom($Second)" />

random:getRandom($First) function works properly

but  random:getRandom($Second)  function gives error  when  I used variable "Second" in this function , I think it is not getting value from "Second" variable. In my xslt file I have to use  <xsl:variable name="Second" select="count($currentPage/ancestor-or-self::node/descendant-or-self::node[@nodeTypeAlias = 'test1'] )"/> 

this syntax, but its not work

Please help me , I got stuck by this error , It wasted a lot of my time.

Any help should be appreciable , Thanks in advance.
