Re: XSLT: check if value is whitespace(s)

if check in xsl
Off the top of my head it seems the easiest would be to use the translate function within the select attribute of a variable to convert spaces into non-spaces (nothing) and then use a simple boolean test to determine what to do next if it returns false... For example...

<xsl:variable name="testWhiteSpace" select="translate(foo/bar, ' ', '')" />

<xsl:if test="$testWhiteSpace">
...do something
</xsl:if>

Untested.

Hope this helps!

Hi,

is there a way to check if a given value is whitespace(s) only? A function maybe?

Thanks,
Ralph
