Don't know the C API, but in XSLT there's the function normalize-space()
and it does just what you want, so you might want to take a look at the
source of LibXSLT. Or use XSLT directly.


<xsl:stylesheet version="1.0"
        xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>

        <xsl:template match="text()" priority="2">
                <xsl:copy-of select="normalize-space()"/>
        </xsl:template>

        <xsl:template match="@*|node()">
                <xsl:copy>
                        <xsl:apply-templates select="@*|node()"/>
                </xsl:copy>
        </xsl:template>

</xsl:stylesheet>
