[Exist-open] Antw: Xquery Update Extension Error
|
From: Markus S. K. <mar...@bs...> - 2010-12-09 09:19:47

Hello again,
I need to add some code to make understanding my problem easier. The
following is a fragment of the XQuery code I want to run:
<code>
let $node := doc($docPath)//TEI:placeName[@xml:id eq
$id]
return (
if (matches($element, "-NAM$")) then (
let $oldValue := $node/text()[1],
$newValue :=
request:get-parameter($element, ()),
$values := concat($oldValue, "_old | ",
$newValue, "_new")
return
<update>
<id>{$id}</id>
<val>{$values}</val>
{update replace $oldValue with
$newValue}
</update>
)
else if (matches($element, "-DAT$")) then (
let $oldValue := $node//TEI:date/text(),
$newValue :=
request:get-parameter($element, ()),
$values := concat($oldValue, "_old | ",
$newValue, "_new")
return
<update>
<id>{$id}</id>
<val>{$values}</val>
{update replace $oldValue with
$newValue}
</update>
)
else if (matches($element, "-SRC$")) then (
let $oldValue := $node//TEI:ptr/@target,
$newValue := concat("#",
request:get-parameter($element, ())),
$values := concat($oldValue, "_old | ",
$newValue, "_new")
return
<update>
<id>{$id}</id>
<val>{$values}</val>
{update replace $oldValue with
$newValue}
</update>
)
else ()
)
</code>
While the first and the third if-statements work perfectly fine, the
second one doesnt. The TEI namespace is declared and the content I am
getting returned through $values is always correct, so I assume that the
XPath must be just fine as well.
I have tried to exchange "update replace" with "update value", to add
[1] to text() or to use "$node//TEI:date/." instead. But the problem
remains: I either get a 'Error 500 An unknown error occurred: Array
index out of range: -1' (for server trace see below) or a 'Type
mismatch: an element can only be replaced by an element.' error. Here is
an example of one of the nodes I need to update (document is in TEI
namespace, sending xml:id with specific additions like "-DAT" via
POST):
<code>
<placeName xml:id="ODB_S00017413_NAM001" xml:lang="de-DE" type="main"
cert="high">
Niederthann
<note type="source">
<date ana="#notBefore">2001-04-08T10:15:00</date>
<bibl>
<ptr target="#HAB/Laube"/>
</bibl>
</note>
</placeName>
</code>
I thought that maybe the text of the date-element was the problem so I
changed it to something simple but didnt help either. Any help would be
very much appreciated because I am pretty stuck with this problem.
Thanks in advance!
Regards,
Markus

Hi,
having a problem updating a text node within a TEI XML document using
the Xquery Update Exentions on a standalone server. The approach works
perfectly fine with other (parent) nodes and even updating the node
itself is working. Just cant replace the text using 'update replace /
value' because I am getting a "HTTP ERROR: 500 An unknown error
occurred: Array index out of range: -1" (cf. output of server further
down).
The XPath expression is correct. Do you happen to have any idea how to
solve this? Thanks for your help,
Markus
