I have embedded XML in HTML and wanted to use find to traverse it, while this worked very well in IE7, on firefox3 was a mess, after some testing I realized it was because of self-closed tags. So the following XML

<Section id="6" name="Compliance">

<Requirement id="6.1">

<Description>Compliance</Description>

<AppliesTo>

<Characteristic></Characteristic>

</AppliesTo>

<Recommendations>

<General>Identify compliance required by your application</General>

<Java></Java>

<DotNET></DotNET>

<PHP></PHP>

</Recommendations>

</Requirement>

</Section>

will become

<Section id="6" name="Compliance">

<Requirement id="6.1">

<Description>Compliance</Description>

<AppliesTo>

<Characteristic></Characteristic>

<Recommendations>

<General>Identify compliance required by your application</General>

<Java>

<DotNET>

<PHP></PHP>

</DotNET>

</Recommendations>

</Requirement>

</Section>

</Java>

If I change the <Java/> tag to <Java></Java> traversing works fine.
