Thanks Wendell, Joel, and Graydon! I will use your suggestions and see what I get and whether I can apply the lessons to other places I need to get rid of white space. I am at least a little gratified that this is not an easy problem causing the bumps on my forehead. Joel, to answer your question (incompletely), given <p> <anchor> </anchor> The rain in <bold> <underline> Spain </underline> </bold> <italic> is </italic> wet. </p> I'd likely want <p><anchor> </anchor> The rain in <bold> <underline> Spain </underline> </bold> <italic> is </italic> wet.</p> That is, remove the leading and trailing spaces caused by indentation, and assume every other space weirdness that occurs between the first non-whitespace character and the last non-whitespace character in <p> is correct. The tricky bit is the <anchor> element--space after or no space after?--which luckily is not analogous to a structure I will face in the paragraph case, but I may when I get to tables (yay!). In tables I fear that some line breaks will be junk and others used to get rendering they want, which will be near impossible to tease out.

I am not sure IB would use xsl:analyze-string here since asB you observe it can be (um) pesky. I might do something as simple as <xsl:template match=" text()[. is ancestor::p/descendant::text()[1]]"> B <xsl:value-of select=" replace($str,'^\s*','') "/> </xsl:template> But the match might have to be greedier if the inline markup is also deep,B and this is only the front end. This is not an easy problem since the (very smart) computer doesn't know the difference between "white space that matters" and "white space that doesn't matter". Indeed its whole notion of "white space" is somewhat problematic. So I'm not sure who's actually smarter. :-) Cheers, Wendell
