I need to take output like below using xsl 1.0 or 2.0
<products>
<supplier>
<supplierid>1001</supplierid>
<totalprice>23</totalprice>
<items>
<item>Pencil</item>
<price>8</price>
</items>
<items>
<item>Pen</item>
<price>5</price>
</items>
<items>
<item>Bag</item>
<price>10</price>
</items>
</supplier>
<supplier>
<supplierid>1001</supplierid>
<totalprice>24</totalprice>
<items>
<item>Paper Box</item>
<price>7</price>
</items>
<items>
<item>Pen</item>
<price>4</price>
</items>
<items>
<item>Bag</item>
<price>13</price>
</items>
</supplier>
<supplier>
<supplierid>1002</supplierid>
<totalprice>26</totalprice>
<items>
<item>Sharpner Box</item>
<price>7</price>
</items>
<items>
<item>Pen</item>
<price>4</price>
</items>
<items>
<item>Bag</item>
<price>15</price>
</items>
</supplier>
</products>
Sort less price from "same suppliers" for example <supplierid>1001</supplierid>
Based on there sub nodes <items>
1001/23 and 1001/30 is same based on there <items><item>. we need to remove 1001/30 from the list. because it is high price

Answer 1

Based on the assumption that you like to sort suppliers based on their totalprice:
<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema" version="2.0">
<xsl:template match="/">
<products>
<xsl:for-each select="products/supplier">
<xsl:sort select="totalprice" data-type="number" order="ascending"/>
<xsl:copy-of select="."/>
</xsl:for-each>
</products>
</xsl:template>
</xsl:transform>

Answer 2

This will first sort based on supplierid and secondly based on their totalprice
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="#*|node()">
<xsl:copy>
<xsl:apply-templates select="#*|node()">
<xsl:sort select="supplierid"/> <!-- 1st level sorting -->
<xsl:sort select="totalprice"/> <!-- 2nd level sorting -->
<xsl:sort select="price"/> <!-- 3rd level sorting -->
</xsl:apply-templates>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
Note: You can use a free online tool called Online XSLT Test Tool to test your xml/xslt files.
