How are empty text-nodes processed?

If i apply the following xslt 

<xsl:stylesheet version="2.0"
          xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output method="html" indent="yes"/>

    <xsl:template match="*">
        <xsl:copy><xsl:apply-templates/></xsl:copy>
    </xsl:template>

    <xsl:template match="b/*">
        <xsl:copy><xsl:apply-templates/></xsl:copy>
    </xsl:template>

    <xsl:template match="text()">text</xsl:template>

</xsl:stylesheet>

on the following xml 

<?xml version="1.0"?>

<a>
   <b></b>
</a>

the output is

<a>
    text
    <b></b>
    text
</a>

What i don't get: All the empty text-nodes between the elements get processed except the empty text-node inside the element b. I don't see any difference on how the child elements of a and b are processed.

Solution

  • There is no empty text node inside the b element, it is an empty element that has no child nodes at all. On the other hand, the a element has three child nodes, the first is a text node with whitespace (at least a line break and some space or tab characters), the second is the b element, the third is a text node with white space (at least a line break).

    Also where did you get that result with the indentation of the text output you have shown? At http://xsltransform.hikmatu.com/94hvTyG I get the output <a>text<b></b>text</a>
