xml - XPath - extract value from parent with highest node value -

this xml snippet

<financialsummary> <summarydate format="yyyymmdd">20111231</summarydate> <revenue currency="eur">1249164523</revenue> </financialsummary> <financialsummary> <summarydate format="yyyymmdd">20101231</summarydate> <revenue currency="eur">1242344523</revenue> </financialsummary> <financialsummary> <summarydate format="yyyymmdd">20091231</summarydate> <revenue currency="eur">324900932</revenue> </financialsummary>

im trying extract node content revenue node within financialsummary tag highest numeric summarydate value.

/financialsummary[summarydate = '20111231']/revenue

this xpath returns right = 1249164523

max(/financialsummary/summarydate)

this xpath returns right = 20111231

however when seek combine both nil returned

/financialsummary[summarydate = max(/financialsummary/summarydate)]/revenue

is there missing? solution puzzle?

extra information: tried contains instead of '=' no luck that

i think look answers question :

financialsummary[summarydate = max(./parent::*/financialsummary/summarydate)]/revenue

the context in predicate financialsummary. have in th tree others. look can homecoming several nodes, if have same date.

edit :

i remove first slash. consequence : have in right context (parent of financialsummary) launch xpath query.

xml xpath xsd xpath-2.0

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
