Hi Folks,
I am trying to stream-process this web site which emits a continuous stream of
XML:
http://xmpp.wordpress.com:8008/firehose.xml?type=text/plain
Ergo, I use xsl:stream like so:
<xsl:stream
href="http://xmpp.wordpress.com:8008/firehose.xml?type=text/plain">
...
</xsl:stream>
The XML that the web site delivers consists of an infinitely long sequence of
Atom <entry> elements. I want to iterate through them and keep a running count.
Ergo, I embed xsl:iterate inside xsl:stream like so:
<xsl:stream
href="http://xmpp.wordpress.com:8008/firehose.xml?type=text/plain">
<xsl:iterate select="stream/atom:entry ">
<xsl:param name="count" select="1" as="xs:integer"/>
...
</xsl:iterate>
</xsl:stream>
However, that results in Saxon throwing this error:
The body of the xsl:stream instruction is not guaranteed streamable according
to W3C rules
* Context item expression (.) in a navigational context is free-ranging
I conclude that xsl:iterate cannot be used in stream-processing. Correct?
