XSLT aggregating XML tag values and storing new tag

Question

I\'m new to xslt and trying to process below XML using XSLT :

F<         


        

Answer 1

Since XSLT variables are immutable, I'm unable perform below operation.

I don't see what variables, immutable or not, have to do with it. This is just straightforward XSLT:

XSLT 1.0

<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="utf-8" indent="yes"/>

<xsl:template match="/xml">
    <xsl:for-each select="characters">
        <word>
            <value>
                <xsl:for-each select="char">
                    <xsl:value-of select="."/>
                </xsl:for-each>
            </value>
            <coordinates>
                <xsl:value-of select="char[1]/@a"/>
                <xsl:text> </xsl:text>
                <xsl:value-of select="char[1]/@b"/>
                <xsl:text> </xsl:text>
                <xsl:value-of select="char[last()]/@y"/>
                <xsl:text> </xsl:text>
                <xsl:value-of select="char[last()]/@z"/>
            </coordinates>
            <avgWeight>
                <xsl:value-of select="sum(characters/char/@weight) div count(characters/char) "/>
            </avgWeight>
        </word>
    </xsl:for-each>
</xsl:template>

</xsl:stylesheet>
