here want details of (tag) in 2nd case fetching (tag) + (tagx) + (tagy) details.

my input similar 2nd input...

its lil urgent... can solution this.

your problem in regular expressions you've written, allow <tagx> (for example) opening tag if there's `' that's supposedly closes on same line.

your problem using regular expressions in case, might bad result if xml is:

<tag></tag> <tagx></tagx> <tag></tag>

if tags inline, whole thing, careful.

i'd work (this works above example):

 <\s*tag((\s+[^<>]+\s*>)|(\s*>))[^<>]*<\s*\/tag\s*>

here, allow whitespaces valid, don't allow nested tags, above example work. moreover, if allow nested tags, no regex work. @ example:

<tag> <tagx> <tag> </tag> </tagx> </tag>

though, in example, <tag> <tagx> <tag> </tag> valid answer.

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
