Question: jQuery('html').css('height') will show height in px. I would like to check if height is set to 100%. Is there any easy way?

Answer: 
You can use `xsl:text` to wrap the plain text you want to output.

```
<xsl:template match="author">
    <xsl:value-of select="@surname" />
    <xsl:if test="count(g)&gt;1">
        <xsl:text>,</xsl:text>
        <xsl:for-each select="g">
            <xsl:value-of select="substring(.,1,1)" />
            <xsl:text>.</xsl:text>
            <xsl:if test="position()!=last()">
                <xsl:text>\,<xsl:text>
            </xsl:if>
        </xsl:for-each>
    </xsl:if>
</xsl:template>

```
Whitespace in the stylesheet is significant only if one of the following conditions applies:

1. it is within an `xsl:text` element
2. it is part of the same text node as non-whitespace characters (as in your example)
3. there is an `xml:space="preserve"` attribute.
