regex |AND| left over data

[Attila Horvath]

All - two quick questions...

1) regex

I am trying to use character range query in regex-pression like:
 a)...
   <xs: restriction base="xs:string">
     <xs:pattern value="[\x00-\x7F]{0,10}"/>
   </cs:restriction>
 |OR|
 b)...
   <xs: restriction base="xs:string">
     <xs:pattern value="[&#x00-&#x7F]{0,10}"/>
   </cs:restriction>
 - either way both throw error(s) re: invalid regex expression syntax.
 - what is correct syntax for range of hex values?

2) my CSV files has CR/LF at end of last line in file
 - when parsing, I get numerous warnings ultimately "left over data"
...starting at byte xyz (0x0d0a...)
 a) how to consume (parse) last two bytes and avoid warnings
 b) how to reconstitute (unparse) so last two bytes are included

Thx in advance
