Vishwajit, it sounds like you are expecting the stripNewline template
to modify the source document, actually removing the newlines from
it so that the following xsl:value-of will be able to recognize the
node you're looking for.  That approach will not work, because in XSL
you're not able to modify the source document.  (That would be a side-
effect, which you're not supposed to be able to do.)

I believe what you want to do here is

<xsl:template mode = "Attribs" match = "info">
<xsl:element name = "PO_NUMBER">
<xsl:value-of select="attr/atomicValue[normalize-space(../name)='ponumber']"/>
</xsl:element>
...
</xsl:template>
