Here is example for XML file.
<?xml version="1.0" encoding="UTF-8"?>
<blueprint xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<apg>
  <channel_object>
    <element1>test1</element1>
    <element2>test2</elemetn1>
  </channel_object>
  <category_system_object>
    <category_label>
	<string> </string>
    </category_label>
  </category_system_object>
</apg>


Here is my XSLT file.
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">


<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="no"/>
<xsl:strip-space elements="*"/>

<xsl:template match="/ | node() | @* | comment() |
processing-instruction()">
  <xsl:copy>
    <xsl:apply-templates select="@* | node()"/>
  </xsl:copy>
</xsl:template>


<xsl:template match="channel_object">
  <advanced_channel_object>
    <xsl:apply-template />
  </advanced_channel_object>
</xsl:template>

</xsl:stylesheet>


I strip out all white space in this transform since I will call
customized pretty-print XSLT later on the better print (that is out of
the scope of this problem).


Thanks,
Jessica

I can think of many different stylesheets that would transform a single
space to a zero-length string, but the chances are that none of them is
the
stylesheet you wrote. Show us some code!
