[xsl] Normalizing Whitespace When Not Using "xsl:value-of"

Is it possible to remove whitespace when inserting values without
using xsl:value-of?

This is my template. It outputs HTML meta tags, but I can't figure out
how to normalize the space when not using xsl:value-of. I'm using xslt
1.0.

Many thanks,
Nathan
