[xslt] Indentation with <xsl:output method="xml" indent="yes"/>

[Vincent Lefevre <vincent+gnome vinc17 org>]

Hi,

I don't understand how indentation is done with
<xsl:output method="xml" indent="yes"/>. Perhaps a bug?

*** test.xml:

<?xml version="1.0"?>
<page name="index">
  <page name="p1"/>
  <page name="p2"/>
</page>

*** test.xsl:

<?xml version="1.0"?>

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

<xsl:output method="xml" indent="yes"/>

<xsl:template name="pages">
  <file name="a"/>
  <file name="b"/>
</xsl:template>

<xsl:template match="page">
  <page>
    <alternates>
      <xsl:call-template name="pages"/>
    </alternates>
    <xsl:apply-templates/>
  </page>
</xsl:template>

</xsl:stylesheet>

Here's what I get (Linux, Debian/unstable):

dixsept:~> xsltproc test.xsl test.xml
<?xml version="1.0"?>
<page><alternates><file name="a"/><file name="b"/></alternates>
  <page><alternates><file name="a"/><file name="b"/></alternates></page>
  <page><alternates><file name="a"/><file name="b"/></alternates></page>
</page>

I wonder why I don't get the same form as with xmllint --format:

dixsept:~> xsltproc test.xsl test.xml | xmllint --format -
<?xml version="1.0"?>
<page>
  <alternates>
    <file name="a"/>
    <file name="b"/>
  </alternates>
  <page>
    <alternates>
      <file name="a"/>
      <file name="b"/>
    </alternates>
  </page>
  <page>
    <alternates>
      <file name="a"/>
      <file name="b"/>
    </alternates>
  </page>
</page>
