Re: [xml] Remove whitespaces from text nodes

[spam spam spam spam free fr]

This solution works correctly, thank you.
It strips leading and trailing whitespace.

But now, I am wondering if there is a solution just using libxml2 (without libxslt).
In fact, I am requesting for a transformation of the XML document.
Indeed, the original node contains whitespaces and I want to remove them...
So I think the answer is "NO!", because this is the job of stylesheets to apply this transformation.

Can someone tell me if there is a way to apply a function which does this work in libxml2 ?

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>
