I have found the reason for one of my streaming problems.I am using uri-collection to read in a bunch of URIs. The xslt3 documentation indicates that one of the reasons uri-collection may be favored over collection() is that the former allows streaming.
However, running the following with the -t command indicates that uri-collection() is causing entire trees to be written into memory in Saxon 126.96.36.199, run through oxYgen:
<xsl:variable name="path" select="replace(base-uri(),'(.*/)[^/]+?.xml','$1')"/>
</xsl:stylesheet>I also tried using xsl:iterate and saxon:iterate [based on the information in the documentation for Saxon 9.3], and trees were being built in all cases.
I don't see how to use saxon:stream() in this case because the entire tree is being built by uri-collection() before the document ever sees saxon:stream().
