Thanks. I'll try that.
How can one find out what is and is not supported in your XQuery
implementation?

Ah, that's trickier.
Would be easy if our XQuery implementation supported the
preceding-sibling:: axis.
let $strings = $anchors/preceding-sibling::text()
Unfortunately, neither the Jaguar nor the Panther versions support this
axis.
Her is a brute force way to get what you want.
let $doc
:=document("http://www.co-ops.nos.noaa.gov/tides04/tab2ec1b.html";)
let $anchors := $doc/A[text()="Predictions"]
let $rawstrings:= tokenize($doc,"")
let $strings :=
for $rs in $rawstrings
let $s1 := if (contains($rs,"")) then substring-after($rs,
"") else $rs
let $s2 := if (contains($s1,"")) then substring-after($s1,
"") else $s1
where not (contains($s2,"<"))
return $s2
return $strings
