A crude way would be to use normalize-space() only if there are no
element children:
<xsl:template match="title-group/article-title[not(*)]" mode="none">
<xsl:value-of select="normalize-space(.)"/>
</xsl:template>
<xsl:template match="title-group/article-title[*]" mode="none">
<xsl:copy-of select="."/>
</xsl:template>
More subtle is to recognize that you can safely remove leading whitespace from
the first text node, and trailing whitespace from the last:
<xsl:template match="title-group/article-title/text()[1]" priority="100">
<xsl:value-of select="replace(., '^\s+', '')"/>
</xsl:template>
<xsl:template match="title-group/article-title/text()[last()]"
priority="101">
<xsl:value-of select="replace(., '\s+$', '')"/>
</xsl:template>
<xsl:template match="title-group/article-title/text()[last()=1]"
priority="102">
<xsl:value-of select="normalize-space(.)"/>
</xsl:template>

hi-
i want to remove trailing whitespace from the contents of an element
(<article-title>), but because that element sometimes contains character-level
formatting elements (<italic>) as well as text, normalize-space is creating problems.
if i use normalize-space(), i lose the italics in the output. (i'm transforming to html.)
here's an example of where i want to remove whitespace (i want to remove the space
before</article-title>):
<title-group>
<article-title>Effect of a Brief Video Intervention on Incident Infection
among Patients Attending Sexually Transmitted Disease Clinics</article-title>
</title-group>
and here's the xsl code i've used:
<xsl:template match="title-group/article-title" mode="none">
<xsl:value-of select="normalize-space(.)"/>
</xsl:template>
this code works most of the time, but in a situation like this:
<article-title>A Global Survey of Gene Regulation during Cold Acclimation
in<italic>Arabidopsis</italic> <italic>thaliana</italic></article-title>
it ends up removing the italic formatting.
does anyone know of a way to strip the whitespace that i don't want (in the
first example) while keeping the character formatting that i do want (in the
second example)?
any pointers would be greatly appreciated.
thanks-
lynn
