Hi Folks,
According to the XSLT specification, when using streaming the XSLT code can
only visit descendant nodes once. In the below code I copy all the child Book
elements (visit #1) and then I count the number of child Book elements (visit
#2). The code works without any errors. Why? It seems like I should have
gotten an error since I visited the child Book elements more than once.
<xsl:template match="BookCatalogue" mode="streaming">
<BookStore>
<xsl:copy-of select="Book"/>
<NumberOfBooks><xsl:value-of
select="count(Book)"/></NumberOfBooks>
</BookStore>
</xsl:template>
