preceding-sibling::node()[self::text()][1]
Actually this should read:
preceding-sibling::node()[1][self::text()]

The node, whose last character we are testing for being a whitespace,
needs to be selected like this:
preceding-sibling::node()[self::text()][1]
And in case there is no such node, a new text node needs to be added,
containing only a single space -- this can be easily done overriding
the identity rule.

One strategy in XSLT 2.0 would be to test for the existence of a space at
the end of the preceding node and add a space if it's not there:
<xsl:template match="unittitle">
<xsl:copy><xsl:apply-templates/></xsl:copy>
</xsl:template>
<xsl:template match="unitdate">
<xsl:choose>
<xsl:when test="preceding-sibling::node()[1][matches(., '\s$')]">
<xsl:value-of select="."/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="concat(' ', .)"/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
which will give you
<unittitle>Statements 2001</unittitle>
<unittitle>Statements 2001</unittitle>
but the following should accomplish the same thing with more concision and
is more robust as it will handle multiple spaces before <unitdate> if they
occur:
<xsl:template match="unittitle">
<xsl:copy>
<xsl:value-of select="string-join((normalize-space(text()),
unitdate), ' ')"/>
</xsl:copy>
</xsl:template>

Is it possible to test a character immediately preceding a node? I
have an element with child-elements, my trouble is that sometimes
there is a space before the child-element, sometimes not. For example
I might have:
<unittitle>Statements <unitdate>2001</unitdate></unittitle>
or
<unittitle>Statements<unitdate>2001</unitdate></unittitle>
The XSLT that I'm forking from has instructions to insert a space
before <unitdate>, which sometimes results in two spaces in the
output. I'd like to use an xsl:choose to test for a space immediately
preceding <unitdate>. Is this possible? I'm using XSLT 2.0.
Thanks,
Nathan
