Hey there, This is out of the MSXML docs. "XSL Transformations (XSLT) provides a built-in function, normalize-space(), that strips leading and trailing white space from a string and normalizes multiple successive white space characters to a single space. It takes one argument, a string or node-set (the latter being converted to a string as necessary); if the argument is omitted, normalize-space() assumes the context node." samples: ------------- in your xml doc ------------- <generouswhitespace> There is a l o t of white space here! </generouswhitespace> ------------- in your xsl doc ------------- <xsl:template match="generouswhitespace"> [<xsl:value-of select="normalize-space(.)" />] </xsl:template> hth., Serdar ----- Original Message ----- From: "Saxena, Saurabh" <saurabh.saxena@i...> To: "'Rick Jelliffe'" <ricko@a...>; <xml-dev@l...> Sent: Wednesday, May 23, 2001 8:36 PM Subject: RE: whitespaces, need a help ! > HI > Even i am facing the same problem.Actually i have a tag in XML file as > <NAME>ABCD></NAME> > Later i am storing this in the database.Now the maximum length for this is > 8.(As defined in the schema file) > What is happening if there is a TAG value like > <NAME>ABCD </NAME> > Then also the validator validates this file successfully and this got > bounced when it goes to the database.Is there any way to trim these > leading/trailing whitespaces. > I can't add anything(extra code) in my XML file as they are > autogenerated.Can something be done at the schema file or in the code where > i am validating the file > regards > saurabh > > > -----Original Message----- > From: Rick Jelliffe [mailto:ricko@a...] > Sent: Wednesday, May 23, 2001 5:29 PM > To: xml-dev@l... > Subject: Re: whitespaces, need a help ! > > > From: Vladimir V.
