Re: Mixed Content Substring()

Your description wasn't very clear, it woul dhave been easier if you'd
have shown the desired output.

<foo>
<bar type="ant"><rub type="glyph">A.</rub> This is a test.</bar>
<bar type="ant"><rub type="glyph">A.</rub>   Another test.</bar>
<bar type="res"><rub type="glyph">R.</rub> This is a test.</bar>
<bar type="res"><rub type="glyph">Res.</rub> This is a test.</bar>
<bar type="res"> Certainly another test.</bar>
<bar type="res"><rub type="glyph">Ant.</rub> Boring test.</bar>
<bar type="ant">This is a test.</bar>
<bar type="hymn"><rub type="glyph">Y.</rub> Lah di Dah.</bar>
</foo>

In most cases above that is a space, but sice you had a normalize-space 
in one of your suggestions I assume you want the first non space letter
in a text node child of bar, which is something like

substring(normalize-space(text()[normalize-space()]),1,1)
