I have this Nunit formated file

<test-results name='IEUnit Tests' total='6' failures='0' not-run='0'
date='6/12/2007' time='2:46 PM'>
<test-suite name='AdministrationPasswordTest' success='true' time='35.396'>
<results>
<test-case name='testChangePasswordFailEmptyForm' executed='true'
success='true' time='5.065'></test-case>
<test-case name='testChangePasswordFailOldPasswordKO' executed='true'
success='true' time='5.066'></test-case>
<test-case name='testChangePasswordFailNewPasswordTooShort' executed='true'
success='true' time='5.049'></test-case>
<test-case name='testChangePasswordFailNewPasswordNotRepeated' executed='true'
success='true' time='5.05'></test-case>
<test-case name='testChangePasswordFailNewPasswordKO' executed='true'
success='true' time='5.066'></test-case>
<test-case name='testChangePassword' executed='true' success='true'
time='10.1'></test-case>
</results>
</test-suite>
</test-results>

it is found and processed by the plugin, but the output is nearly empty:
<?xml version='1.0' encoding='UTF-8'?>
<result>
<suites>
<suite>
<name>AdministrationPasswordTest</name>
<duration>0.0</duration>
<cases/>
</suite>
</suites>
<duration>0.0</duration>
</result>

FYI, here's the xsl I'm using with Bamboo to convert the file in a more JUnit
format:
<?xml version="1.0" encoding="utf-8"?>

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes" encoding="utf-8" version="1.0"
cdata-section-elements="failure" />

<xsl:template match="test-results">
<xsl:element name="testsuite">

<xsl:attribute name="errors">0</xsl:attribute>

<xsl:attribute name="skipped"><xsl:value-of select="@not-run"
/></xsl:attribute>

<xsl:attribute name="tests"><xsl:value-of select="@total" /></xsl:attribute>

<xsl:attribute name="time"><xsl:value-of

<xsl:attribute name="name"><xsl:value-of select="@name" /></xsl:attribute>

<xsl:apply-templates select="current()/test-suite/results" mode="resultsMode" />

</xsl:element>
</xsl:template >

<!-- DECLARING WHAT TO DO WHEN FINDING A "RESULTS" ELEMENT -->
<xsl:template mode="resultsMode" match="results">

<xsl:apply-templates select="current()/test-case" mode="testCaseMode" />
</xsl:template>

<!-- DECLARING WHAT TO DO WHEN FINDING A "TEST-CASE" ELEMENT -->
<xsl:template mode="testCaseMode" match="test-case">

<xsl:element name="testcase">
<xsl:attribute name="time"><xsl:value-of select="@time" /></xsl:attribute>

<xsl:attribute name="name">in file <xsl:value-of
select="current()/../../@name" />.js, <xsl:value-of select="@name"
/></xsl:attribute>

<xsl:apply-templates select="current()/failure" mode="failureMode" />
</xsl:element>

</xsl:template>

<!-- DECLARING WHAT TO DO WHEN FINDING A "FAILURE" ELEMENT -->
<xsl:template mode="failureMode" match="failure">

<xsl:element name="failure">
<xsl:attribute name="type">IEunit failure</xsl:attribute>

<xsl:attribute name="message"><xsl:value-of select="current()/message/."
/></xsl:attribute>
</xsl:element>
</xsl:template>

</xsl:stylesheet>

Hope this helps
