I'm going to store the XPath result set into a "variable," and then iterate the "variable," thusly:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:wt="http://www.example.com" exclude-result-prefixes="wt">

In this example, we are storing the result node set into a "variable," and then proving that the entire set was stored in the "variable." It results in the following output:

I mean these guys don't even have durations! How did they get past the bouncer?
It's probably because we hired a promiscuous bouncer.
We'll just work around that by hiring a second bouncer to stand inside the gate and check invitations:
<h1>Less Than, or Equal to, Ten Hours</h1>
<xsl:variable name="less_than_ten_hours" select="wt:weetest/wt:elementwrapper[(floor(substring-before(wt:data_duration, ':'))+floor(substring-before(substring-after(wt:data_duration, ':'),':')))<=10]"/>
<xsl:for-each select="$less_than_ten_hours">
<xsl:if test="wt:data_duration!= ''">
<xsl:call-template name="render_one"/>
</xsl:if>
</xsl:for-each>
Which results in:
<h1>Less Than, or Equal to, Ten Hours</h1>
<div class="alt_1">
<div class="duration_display">The duration is 1 hour and 5 minutes long.</div>
<div class="display"><a href="http://www.example.com/wee_test.html">Test (cat 1)</a></div>
</div>
<div class="alt_1">
<div class="duration_display">The duration is 10 hours long.</div>
<div class="display">Test (cat 2)</div>
</div>
Whew! That did it! Go Me! Go Me!
<cough> uh, sir...
<h1>Less Than, or Equal to, Ten Hours</h1>
<div class="alt_1">
<div class="duration_display">The duration is 1 hour and 5 minutes long.</div>
<div class="display"><a href="http://www.example.com/wee_test.html">Test (cat 1)</a></div>
</div>
<div class="alt_1">
<div class="duration_display">The duration is 10 hours long.</div>
<div class="display">Test (cat 2)</div>
</div>
This is why we need to solve the problem in the XPath expression; not in a patched-in bit of e-spackling.
We need to sober up the bouncer, not hire a second one:
<h1>Less Than, or Equal to, Ten Hours</h1>
<xsl:variable name="less_than_ten_hours"
select="wt:weetest/wt:elementwrapper[((floor(substring-before(wt:data_duration, ':'))+floor(substring-before(substring-after(wt:data_duration, ':'),':')))<=10)and(wt:data_duration!= '')]"/>
<xsl:for-each select="$less_than_ten_hours">
<xsl:call-template name="render_one"/>
</xsl:for-each>
Which results in:
<h1>Less Than, or Equal to, Ten Hours</h1>
<div class="alt_1">
<div class="duration_display">The duration is 1 hour and 5 minutes long.</div>
<div class="display"><a href="http://www.example.com/wee_test.html">Test (cat 1)</a></div>
</div>
<div class="alt_0">
<div class="duration_display">The duration is 10 hours long.</div>
<div class="display">Test (cat 2)</div>
</div>
That's better.

In the original test for less-than, I specified the "<" as "<". This is because XML don't want us to use the "<" character for anything but opening elements.
Awkward, but understandable. It works fine, just looks bad. However, this is at the end of a line of gobbledygook that makes me wince, so I'm not gonna cry over it.
<div class="alt_1">
<div class="duration_display">The duration is 10 hours long.</div>
<div class="display">Test (cat 2)</div>
</div>
Should have been:
<div class="alt_1">
<div class="duration_display">The duration is 10 hours long.</div>
<div class="display">Test (cat 2)</div>
</div>
