275824 - Essential node navigation in XSLT fails

Status: RESOLVED DUPLICATE of bug 187620

(Core :: XSLT, defect)

Description

[mitchgould]

Although many examples from "XSLT Quickly" by Bob Ducharme succeed in Mozilla,
some others fail without an error message, resulting in a gray client window.
This includes important node-navigation tasks in XSLT (attached).

[Jonas Sicking (:sicking) No longer reading bugmail consistently]

The problem is that the stylesheet doesn't create a complete document. The
stylesheet tries to create a bunch of text, but this text is insert directly in
the root of the document. However, since textnodes aren't allowed there they are
ignored.

Note that the stylesheet isn't broken per se. XSLT does allow you to create
results that aren't complete documents. So it could be argued that we should be
able to deal.

To work around this place a element around the created contents, like:
<xsl:template match="item[3]">
<result>
~~~~ Start of item element's template ~~~~
...
~~~~ End of item element's template ~~~~
</result>
</xsl:template>


or add an <output method="text">
