Try this:
XML:
<?xml version="1.0" encoding="UTF-8"?>
<Books>
<book>
<price>20</price>
</book>
<book>
<price>10</price>
</book>
<book>
<price>5</price>
</book>
<book>
<price>100</price>
</book>
</Books>
XSLT:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<xsl:value-of select="/Books/book[not(price > ../book/price)]/price"/>
</xsl:template>
</xsl:stylesheet>
cheers

Subject: [xsl] Finding the lowest 'price' element
Hi all,
I have several book elements, in which each book element has a
'price' child element.
<book>
<price>20</price>
</book>
<book>
<price>10</price>
</book>
.
.
.
Now, I need to find the lowest 'price' element using XSLT?
One solution which i think is:
1. first sort the above xml document using <xsl:sort>
2. Now we get a new tree with all the price elements in
ascending order.
3. Now we will find the first 'price' element which is the
lowest using the "position()" function.
Here the result tree is again fed with a new stylesheet(to find
the first position), to the xslt processor.
Is there any better solution than this?
Thanks in advance!!
