xpath - How do I replace sequences of whitespaces by one space but don't trim in XSLT? -


the function normalize-space removes leading , trailing whitespace , replaces sequences of whitespace characters single space. how can only replaces sequences of whitespace characters single space in xslt 1.0? instance "..x.y...\n\t..z." (spaces replaced dot readability) should become ".x.y.z.".

without becker's method, use discouraged character mark:

translate(normalize-space(concat('',.,'')),'','')

note: 3 function calls...

or character repeating expression:

substring(    normalize-space(concat('.',.,'.')),    2,    string-length(normalize-space(concat('.',.,'.'))) - 2 )

in xslt can declare variable:

<xsl:variable name="vnormalize" select="normalize-space(concat('.',.,'.'))"/> <xsl:value-of select="susbtring($vnormalize,2,string-length($vnormalize)-2)"/>
