Leave your existing template as it is and add:
<xsl:template match="strong[normalize-space(.) = '']" mode="inline"/>
Note that the marks between the "=" and "]" are two single-quotes.
Due to the non-trivial match pattern, this will be a higher-priority
template than your existing one, so it will override it for the cases
that it matches. The normalize-space() function will trim whitespace
from the start and end and collapse it in the middle, so it's very
handy for "text content other than whitespace" tests.

Despite doing XSLT work for the past few years I still feel like a novice. I
have hit the wall on a specific problem which I should think would be easy to
solve.
BACKGROUND
I am processing a XML file that I want to convert to HTML. Everything works
fine unless there is an empty <strong /> tag in it. This happens because the
source document originated from Adobe InCopy and in cutting a pasting a bold
style that is applied to the space between characters is left in the
document. My XSLT ends up creating a <strong /> tag in this case which is
disliked by web browsers, they see this as a "begin strong tag" resulting in
bolding that is never turned off.
My XSLT is taking a intermediary XML file, not the XML generated directly
from InCopy.
MY CODE
When I get to processing the contents of the document I use a bunch of
xsl:template tags. I never know if any paragraphs will have strong, em, or br
tags within it.
Here is a snippet of the XML document being processed:
<Main_Body>
<strong>For the Quads</strong>
</Main_Body>
<Main_Body>Place one foot on a step or bench so the quadricep is
parallel to the floor.
Place the Stick on the top of the quadricep and slowly roll it
on top of the muscle
while applying pressure. Continue rolling for about 30
seconds. Switch legs and
repeat.</Main_Body>
Here is a snippet of the XSLT code:
<xsl:template match="SubHead1" mode="inline">
<h4 class="headline"><xsl:apply-templates mode="inline"/></h4>
</xsl:template>
<xsl:template match="SubHead2" mode="inline">
<h5 class="subheadline"><xsl:apply-templates
mode="inline"/></h5>
</xsl:template>
<xsl:template match="Main_Body" mode="inline">
<p><xsl:apply-templates mode="inline"/></p>
</xsl:template>
<xsl:template match="strong" mode="inline">
<strong><xsl:apply-templates mode="inline"/></strong>
</xsl:template>
<xsl:template match="em" mode="inline">
<em><xsl:apply-templates mode="inline"/></em>
</xsl:template>
<xsl:template match="a" mode="inline">
<xsl:copy-of select="." copy-namespaces="no"/>
</xsl:template>
<xsl:template match="br" mode="inline">
<br/>
</xsl:template>
My problem is that if 'match="strong"' and if the string of the strong tag is
empty, I don't want to generate any results. I have attempted to use the
xsl:if tag but it doesn't work because I am already in the contents of the
<strong> tags. I have been attempting to put in some sort of conditional
statement in the xsl:template when match="strong" to say 'if there is no
content don't do anything'. I just can't think of any way of writing that.
Or perhaps my approach is just wrong.
