i try it with

count(object/node[@meta='27']/data

you count data????

[(@meta='13' and contains(.,'a'))
with a meta attribute of 13 and containing an 'a'

and (@meta='14' and contains(.,'b'))])

!and! with a meta attribute of 14 and containing an 'b'

your are looking for:
<data meta="13" meta="14">ab</data>

This would help:

<xsl:value-of select="
count(object/node[@meta=27 and ((data[@meta=13] and contains(.,'a')))
and (data[@meta=14] and contains(.,'b'))])" />

i try it with
count(object/node[@meta='27']/data[(@meta='13' and contains(.,'a'))
and (@meta='14' and contains(.,'b'))])

That counts data elements having a meta attribute of 13 and a meta
attribute of 14. No element has two meta attributes, so you get no
matches.

You want to count nodes:

count(object/node[...])

where the node has a data child with @meta='13' and which contains 'a':

data[@meta='13' and contains(., 'a')]

and similarly

data[@meta='14' and contains(., 'b')]

so put those two conditions in the predicate.
