xpath sequence methods and subscripts

[rvj]

1. anyone got an example of how to return the results of a sequence method
such as tokenize ?

<assign var="?alltokens" expr="tokenize('in the beginning') />

2. or how to return the second "token" - some kind of subscript on data??

<assign var="?secondtoken" expr="data(tokenize('in the beginning'),2)
/>

I guess it's subsequence !

.....is this the correct syntax to return "the"?

<assign var="?secondtoken" expr="subsequence('in','the','beginning'),2)"
/>

or

<assign var="?secondtoken" expr="subsequence(tokenize(@phrase),2)"

where @phrase is "in the beginning"

I am not sure what technology you are trying to use. This is the Mozilla
newsgroup for XML. tokenize is a function supported in XPath and XSLT
2.0 and in XQuery 1.0 but as far as I know Mozilla does only support
XSLT and XPath 1.0 which does not know any sequences.

In XPath 2.0 to access the second item in the sequence $foo is simply
$foo[2]
so
tokenize('in the beginning', ' ')[2]
should give you the string 'the'.
