You'll need to explain (a) what output you want, and (b) where you are having difficulty. I'd suggest you simplify the problem a bit, and also think about yor question from the point of view of someone trying to answer it. I could write you some code that transformed your data into SVG, but (a) it would be quite unlike the SVG representation that you want to achieve, and (b) it wouldn't help you over your learning difficulties.

sorry not to make understand me… what I need specifically is how I can defining a XSLT to transform a document PMML into a SVG that allows me to visualize the model graphically, or a graph of pie, bar charts or any other.
sorry about my English because I don´t speak English very well

Your English isn't a problem.

If this were an assignment that I was being paid for, I would budget a couple of days for it, and I would start by asking for a more detailed statement of requirements.

But it's not an assignment I'm being paid for, it's a project of yours where you need help. So you need to explain where you are stuck, what part of the problem are you having difficulty with? What part of the XSLT language don't you understand?

I need exactly to transform previous pmml into a cluster graph and showing to both cluster that she gives this pmml me like exit in a system of coordinates x,y. but I don´t know how making it, and if you were so amiable to solve this problem for me , the problem is that I specifically need that example for in a moment and don´t know anything about the subject... please help me I need you very most.

I'm sorry, I do my best here to try and help people solve simple coding problems, but I can't write complete stylesheets for people, let alone design them from a very incomplete statement of requirements. That's consultancy, and I make my living from it.

This is my XML source:

and this is my XSLT source:

That I need is: how can I read the set value of Array tag because I try with this xslt code but I can't obtain the Array's values as number. for build the svg output.

Thanks for your help

It's a shame that the items in Array haven't been marked up as individual elements, that would have made your life easier.

In XSLT 2.0 it's easy to split the list into tokens using the tokenize() function. For XSLT 1.0 you need a recursive template to do the job, you can find one called str:tokenize at www.exslt.org.

Hello:

Thanks for your last reply. It help me so much.

But I have some another problem, when I store the value into variable "tokens" after do the "split" function, I not obtain all values of the array, I just obtain the first value for each iteration.

I did this code in static form:

    <?xml version="1.0" encoding="UTF-8"?>
  <xsl:stylesheet version="1.0"
                  xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:str="http://exslt.org/strings"
                  extension-element-prefixes="str"
 xmlns:pmml="http://www.dmg.org/PMML-3_0">

    <xsl:import href="split/str.split.xsl"/>

    <xsl:template match="pmml:ClusteringModel">
        <svg width="200px" height="250px">
        <xsl:for-each select="pmml:Cluster ">

            <xsl:variable name="value" select="pmml:Array"/>

            <xsl:variable name="tokens">
                <xsl:call-template name="str:split">
                    <xsl:with-param name="string" select="$value"/>
                    <xsl:with-param name="pattern" select="','"/>
                </xsl:call-template>
            </xsl:variable>

            <g id="bar" transform="translate(0,200)">
                <xsl:for-each select="$tokens">

                        <xsl:variable name="XY1" select="token[1]"/>
                        <rect x="{$XY1 * 100}" y="-{$XY1 * 100}"
                                fill="black" width="0.1"
                                height="0.1" stroke="black"
                                stroke-width="2"/>

                        <xsl:variable name="XY2" select="token[2]"/>
                        <rect x="{$XY2 * 100}" y="-{$XY2 * 100}"
                                fill="black" width="0.1"
                                height="0.1" stroke="black"
                                stroke-width="2"/>

                        <xsl:variable name="XY3" select="token[3]"/>
                        <rect x="{$XY3 * 100}" y="-{$XY3 * 100}"
                                fill="black" width="0.1"
                                height="0.1" stroke="black"
                                stroke-width="2"/>

                        <xsl:variable name="XY4" select="token[4]"/>
                        <rect x="{$XY4 * 100}" y="-{$XY4 * 100}"
                                fill="black" width="0.1"
                                height="0.1" stroke="red"
                                stroke-width="2"/>

                        <xsl:variable name="XY5" select="token[5]"/>
                        <rect x="{$XY5 * 100}" y="-{$XY5 * 100}"
                                fill="black" width="0.1"
                                height="0.1" stroke="red"
                                stroke-width="2"/>

                </xsl:for-each>
            </g>
        </xsl:for-each>
        </svg>
    </xsl:template>

</xsl:stylesheet>


 Now my question is how I can obtain the same result in dynamic form?

You seem to be using comma as a separator in your call to str:split whereas your data uses a space. Don't know if that's the whole problem though.

A conformant XSLT 1.0 processor will not allow you to use a result tree fragment in this way; you need to convert it to a nodeset using the exslt:node-set() function. Some processors allow you to get away with it. But since it's outside the standard, it may not be doing what you expect.

A useful diagnostic is to insert

<debug>
  <xsl:copy-of select="$tokens"/>
<debug>
