Problems converting XML to JSON using XSLT
Only write the comma if there is another cd element in your xml.
So basically you have to wrap that comma in a xsl:if statement like this: <xsl:if test="./following-sibling::cd">,</xsl:if>
So your stylesheet will look something like that:
<?xml version="1.0" encoding="UTF-8"?><xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> <xsl:template match="/"> {"catalog":[ <xsl:for-each select="catalog/cd"> {"title":" <xsl:value-of select="title" /> ","artist":" <xsl:value-of select="artist" /> "}<xsl:if test="./following-sibling::cd">,</xsl:if> </xsl:for-each> ] } </xsl:template></xsl:stylesheet>
