Name
normalize-space()
Removes extra whitespace from its argument string.
Syntax
[1.0] stringnormalize-space(
string?
)
[2.0] xs:stringnormalize-space(
xs:string?
)
Inputs
An optional string. If the argument is omitted, the normalize-space()
function uses the
string value of the context node.
[2.0] If the argument is the empty
sequence, normalize-space()
returns a zero-length string.
Output
The argument string, with whitespace removed as follows:
All leading whitespace is removed.
All trailing whitespace is removed.
Within the string, any sequence of whitespace characters is replaced with a single space.
If the string is all whitespace, a zero-length string is returned.
[2.0] In XSLT 2.0, passing the empty
sequence to normalize-space()
returns the empty
sequence.
Defined in
[1.0] XPath section 4.2, “String Functions.”
[2.0] XQuery 1.0 and XPath 2.0 Functions and Operators section 7.4, “Functions on String Values.”
Example
Here is a short example that demonstrates how normalize-space()
works:
<?xml version="1.0"?>
<!-- normalize-space1.xsl --> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output method="text"/> <xsl:variable name="newline"> <xsl:text>
</xsl:text> </xsl:variable> <xsl:variable name="testString"> <xsl:text> This is a string that had 		 lots of 


 whitespace. </xsl:text> </xsl:variable> <xsl:template match="/"> <xsl:text>
Tests of the normalize-space() function:</xsl:text> <xsl:text>

 normalize-space(' </xsl:text> ...
