Add comma as delimiter when creating array of arra

My actual data is as follows :

<image name="101272.dcm">
<gobject type="Right"><polyline><vertex index="0" t="0.0" x="636.0" y="1920.0" z="0.0"/><vertex index="1" t="0.0" x="604.0" y="2296.0" z="0.0"/></polyline></gobject>
</image>
<image name="101280.dcm">
<gobject type="Right"><polyline><vertex index="0" t="0.0" x="1776.0" y="392.0" z="0.0"/><vertex index="1" t="0.0" x="1456.0" y="424.0" z="0.0"/></polyline></gobject>
</image>

I was successful in extracting all other data as required. But using the comma as delimiter is painful as Im a beginner in xslt.

Im using xslt version 2 and my code is :

<xsl:stylesheet version="2.0"
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output omit-xml-declaration="yes" indent="yes"/>
    <xsl:strip-space elements="*"/>
    <xsl:template match="/">
            seriesUID,annotationType,coordSys,data,name,label

        <xsl:for-each select="//gobject">
            <xsl:variable name="seriesUID" select="ancestor::image/@name"/>
            <xsl:value-of select="substring-before($seriesUID,'.dcm')"/>
            <xsl:value-of select="concat(',','polygon')"/>
            <xsl:value-of select="@annotationType"/>
            <xsl:value-of select="concat(',','Image')"/>
            <xsl:value-of select="@coordSys"/>
            <xsl:value-of select="concat(',','[')"/>
            <xsl:for-each select="polyline/vertex">
                <xsl:value-of select="concat('','[')"/>
                <xsl:value-of select="@x"/>
                <xsl:value-of select="@y"/>
                <xsl:value-of select="@z"/>
                <xsl:value-of select="concat(']','')"/>
            </xsl:for-each>
            <xsl:value-of select="concat(']','',',')"/>
            <xsl:value-of select="@type"/>
            <xsl:value-of select="concat(',','')"/>
            <xsl:value-of select="@label"/>
            <xsl:value-of select="concat(',','&#xA;')"/>
        </xsl:for-each>
    </xsl:template>
</xsl:stylesheet>

Generating below output :

seriesUID   annotationType  coordSys    data    name    label

1006780 polygon Image ["[3476.0,1196.0,0.0],"[3436.0,1036.0,0.0],] Right
1006810 polygon Image ["[3064.0,744.0,0.0],"[3300.0,912.0,0.0],] Right

Please help me eliminate the double quote marks and the last COMMA in the field data.

If you can only use XSLT 2.0, then this is how you could do it...

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">
<xsl:output method="text" />

<xsl:template match="/">
    <xsl:text>type,data,label&#10;</xsl:text>
    <xsl:apply-templates select="//parent" />
</xsl:template>

<xsl:template match="parent">
    <xsl:value-of select="@type" />
    <xsl:text>,"[</xsl:text>
    <xsl:value-of select="child1/child2/concat('[',@x,',',@y,',',@z,']')" separator="," />
    <xsl:text>]",hard coded&#10;</xsl:text>
</xsl:template>
</xsl:stylesheet>

EDIT: I am wondering if indeed you are using XSLT 2.0. Simply putting version="2.0" in a stylesheet won't achieve anything unless you have an XSLT processor that supports it.

If this is the case, here is an XSLT 1.0 version of the previous XSLT

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">
<xsl:output method="text" />

<xsl:template match="/">
    <xsl:text>type,data,label&#10;</xsl:text>
    <xsl:apply-templates select="//parent" />
</xsl:template>

<xsl:template match="parent">
    <xsl:value-of select="@type" />
    <xsl:text>,"[</xsl:text>
    <xsl:for-each select="child1/child2">
        <xsl:if test="position() > 1">,</xsl:if>
        <xsl:value-of select="concat('[',@x,',',@y,',',@z,']')" />        
    </xsl:for-each>
    <xsl:text>]",hard coded&#10;</xsl:text>
</xsl:template>

</xsl:stylesheet>

You should be able to adapt this to your new XML hopefully.

Note: To see what XSLT processor and version you actually have, see this question...

How can I check which XSLT processor is being used in Solr?
