I am looking for given string, it has to be in *(*)
format, *
should not have space, no two words before (
.
I am searching MarkLogic DB to see if given column value is in [^\s]+\((?!\s)[^()]+(?<!\s)\)
format, if not replace it with this format.
I am still stuck at fetching data, and could not write the query to update
I am searching DB as
let $query-opts := cts:search(doc(),
cts:and-query((
cts:directory-query(("/xyz/documentData/"),"1"),
cts:element-query(
xs:QName("cd:clause"), (: <clause> element inside extended for checking query id :)
cts:and-query((
cts:element-attribute-value-query( xs:QName("cd:clause"), xs:QName("tag"), "Title" ), (: only if the <clause> is of type "Title" :)
cts:element-attribute-value-query( xs:QName("cd:xmetadata"), xs:QName("tag"), "Author")
))
)
))
for $d in $query-opts
return (
for $x in $d//cd:document/cd:clause/cd:xmetadata[fn:matches(@tag,"Author")]/cd:metadata_string
where fn:matches($x/string(), "[^\s]+\((?!\s)[^()]+(?<!\s)\)")
return
( <documents> {
<documentId> {$d//cd:cdf/cd:documentId/string()}</documentId>
}</documents>
)
)
It's throwing up error invalid pattern
The fn:matches
function does not support group modifiers like (?!
and (?<!
. Simplify your pattern, and capture false positives after the match with another match if necessary.
Doing an educated guess at what you are trying to do, I think you are looking for something like:
where fn:matches($x, '^.+\([^)]+\).*$') (: it uses parentheses :)
and fn:not(fn:matches($x, '^[^\s]+\([^\s)]+\)$')) (: but does not comply to strict rules :)
HTH!
