Xml query search by date or number

Question

table :tb column:pxml
<?xml version="1.0" encoding="GBK"?>
<model id="f379f851-b1f9-48bf-8ac7-dafd2b1cedb0" name="hotel" objid="8873dc02-cf83-4527-95bb-e3025469e4ba">
<property id="3100" name="thedate">
<value>2009-09-07</value>
</property>
<property id="3101" name="thenum">
<value>26</value>
</property>
</model>
sql:
select
extractValue(v.pxml,'//property[@name="thedate"]/value'),
extractValue(v.pxml,'//property[@name="thenum"]/value'),
from tb v
where
CONTAINS(v.pxml,'haspath(//property[@name="thenum" and value>="10" and value<="50"])')>0
and to_date(extractValue(v.pxml, '//property[@name="thedate"]/value'),
'yyyy-MM-dd') between to_date('2009-09-01', 'yyyy-MM-dd') and to_date('2009-09-30','yyyy-MM-dd')
the sql had two problems:
1), numeric range comparison wrong, simply finding out the result, but if you can directly =
2), the date type of comparison, I could not find XQUERY program, so use this alternative, the result is correct, but inefficient

You should check and compare the date field mapping with other fields that you have done the correct mapping like other fields , because there should be no issue if mapping is correct, is this entire custom page created by you ? or are you doing changes in existing custom page ?
