Re: Retrieving text and anchor nodes

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,"<A [^<]*</A>")
let $strings :=
for $rs in $rawstrings
let $s1 := if (contains($rs,"</U>")) then substring-after($rs, "</U>") else $rs
let $s2 := if (contains($s1,"</B>")) then substring-after($s1, "</B>") else $s1
where not (contains($s2,"<"))
return $s2
return $strings

Thanks. That is close to what I want, but I also want to get the
preceding sibling text() node. For the first matching anchor in this
example it should be "Newburyport, Merrimack River 420 48.7' 700 51.9'
7.8 9.0 4.2 ".

Try:

let $nodes :=
document("http://www.co-ops.nos.noaa.gov/tides04/tab2ec1b.html";)/
A[text()="Predictions"]/@HREF

This says to first extract those A tags whose text content is
"Predictions" and then grab the HREF attribute from each of them.
