HOWTO indent java code in PDF (with example)

Hi, I'm new in XSL:FO.

I'm programming a tool that tackes a java code file and translates it in XML.

This is my input java code, CiaoMondo.java:

class CiaoMondo extends Object {
    public static void main (String[] args) {
        System.out.println("Hello, World!!");
    }
}

and this is my result in XML, CiaoMondo.xml:

<?xml version="1.0" ?>
<source color="#FFFFFF" size="2" family="Courier New, Courier">
<br/><word color='#00FF00'>class</word> CiaoMondo <word color='#00FF00'>extends</word> Object {
<br/><ht num="1"/><word color='#00FF00'>public</word> <word color='#00FF00'>static</word> <base color='#0000FF'>void</base> main (String[] args) {
<br/><ht num="2"/>System.out.println(&quot;Hello, World!!&quot;);
<br/><ht num="1"/>}
<br/>}
</source>

where

the tag <ht num=.../> counts tabs to indent the code

and the other tags for sysntax colouring.

The templates that translate XML in HTML, are this:

<xsl:template match="source" mode="build-source">
  <table border="1">
    <tr><td>
      <font>
        <xsl:attribute name="color"><xsl:value-of select="@color" /></xsl:attribute>
        <xsl:attribute name="size"><xsl:value-of select="@size" /></xsl:attribute>
        <xsl:attribute name="face"><xsl:value-of select="@family" /></xsl:attribute>
        <xsl:apply-templates select="*|text()" mode="build-source" />
      </font>
    </td></tr>
  </table>
</xsl:template>

<xsl:template match="//word" mode="build-source">
  <font>
    <xsl:attribute name="color">
          <xsl:value-of select="@color" />
    </xsl:attribute>
    <xsl:apply-templates select="*|@*|comment()|processing-instruction()|text()" mode="build-source" />
  </font>
</xsl:template>

<xsl:template match="//base" mode="build-source">
  <font>
    <xsl:attribute name="color">
          <xsl:value-of select="@color" />
    </xsl:attribute>
    <xsl:apply-templates select="*|@*|comment()|processing-instruction()|text()" mode="build-source" />
  </font>
</xsl:template>

<xsl:template match="//specialw" mode="build-source">
  <font>
    <xsl:attribute name="color">
          <xsl:value-of select="@color" />
    </xsl:attribute>
    <xsl:apply-templates select="*|@*|comment()|processing-instruction()|text()" mode="build-source" />
  </font>
</xsl:template>

<xsl:template match="//ht" mode="build-source"><xsl:call-template name="htloop" /></xsl:template>

<xsl:template name="htloop" mode="build-source">
<xsl:param name="count" select="1" />
  <xsl:param name="numTabs" select="@num" />
  <xsl:if test="$count &lt;= $numTabs">
    <xsl:text disable-output-escaping="yes">&amp;#xa0;&amp;#xa0;&amp;#xa0;&amp;#xa0;</xsl:text><xsl:call-template name="htloop">
      <xsl:with-param name="count" select="$count+1" />
    </xsl:call-template>
  </xsl:if>
</xsl:template>

This work fine for me!

But, the problem is now to have the same page in PDF.

Any help would be extremly appriciated!!

Thanks,
