xml - How to use xsl/xpath to count all child elements for which a custom function returns true? -

i trying determine if items in list pass test.

i using following line:

<xsl:with-param name="passed" select="count($list/[fn:inrange(., 2, 5)]) = count($list)"/> 

i trying send every child node in list , applying range tool (custom function, works fine). keep getting syntax error.

the problem seems way calling it. specifically, following item:

count($list/[fn:inrange(., 2, 5)]) 

how can achieve want?

try expression instead...

count($list[fn:inrange(., 2, 5)]) 

alternatively, try writing whole expression this:

<xsl:with-param name="passed" select="not($list[not(fn:inrange(., 2, 5))]))"/>
