Create xslt files programmatically

Question

I know that I can create xml files programmatically by using DOM api in java like the following:

DocumentBuilderFactory documentBuilderFactory = 
    DocumentBuilderFactory.newInstance();
DocumentBuilder documentBuilder = documentBuilderFactory.newDocumentBuilder();

Document document = documentBuilder.newDocument();
Element rootElement = document.createElement("map");
document.appendChild(rootElement);

Element em = document.createElement("string");
em.setAttribute("name", "FirstName");
....

But are there any API 's to construct an xslt tree? (an api like Dom for example)

I need somehing like this:

<?xml version="1.0" encoding="iso-8859-1"?>
<xsl:stylesheet version="1.1" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fo="http://www.w3.org/1999/XSL/Format" exclude-result-prefixes="fo">
<xsl:template match="root">
<fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format">
  <fo:layout-master-set>
    <fo:simple-page-master master-name="my-page">
      <fo:region-body margin="1in"/>
    </fo:simple-page-master>
  </fo:layout-master-set>

  <fo:page-sequence master-reference="my-page">
    <fo:flow flow-name="xsl-region-body">
      <fo:block>
        <fo:external-graphic width="100pt" height="100pt" content-width="50pt" content-height="50pt" src="images/shopping-cart_100.jpg"/>
      </fo:block>
      <fo:block>Good Morning, <xsl:value-of select="name" />!</fo:block>
      <fo:block>
        <fo:table>
             <fo:table-body>
                <fo:table-row>
                    <fo:table-cell border="solid 1px black" text-align="center" font-weight="bold">
                        <fo:block>

and:

              <xsl:for-each select="./friend">
                <fo:table-row>
                <fo:table-cell border="solid 1px black" text-align="center">
                    <fo:block>
                        <xsl:value-of select="position()" />
                    </fo:block>
                </fo:table-cell>
                <fo:table-cell border="solid 1px black" text-align="center">
                    <fo:block>
                        <xsl:value-of select="name" />
                    </fo:block>
                </fo:table-cell>
                <fo:table-cell border="solid 1px black" text-align="center">

Thanks in advance.

if you can construct xml, then you can construct xslt.. xslt is XML... — Matt Wolfe

Since XSLT it's XML too, you can simply use the same strategy:

...
Document document = documentBuilder.newDocument();

Element rootElement = document.createElement("xsl:stylesheet");
// adding attributes like namespaces etc...

document.appendChild(rootElement); 
Element em = document.createElement("xsl:template");
em.setAttribute("match", "/");

and so on...

But it's not very elegant. You should use a library or a framework instead, you should easily find one googling around.

Well, it's quite complex :) You can either create the XSLT like I've shown: 'Element rootElement = document.createElement("xsl:stylesheet"); rootElement.setAttribute("version", "1.1");' etc. OR you could try using a library which can help you in doing so... maybe the Apache Cocoon stuff mentioned by Simone Gianni will do the work, but I cannot say as I've never used it before...

You can create an XSLT the same way you create an XML file, since XSLTs are XML files.

However, if you have to deal with XML/XSLT transformations a lot, Apache Cocoon 3 has a very lightweight XML/XSLT pipeline system to use as a library instead of dealing with all XML dom stuff and XSLT transformations manually.

DOM is a pretty cumbersome way of creating XML.

There's a far better way - use XSLT.

The more complex the XML, the bigger the win from using XSLT rather than DOM to create it.

There's no reason why you can't use XSLT to create XSLT (there's even a special declaration xsl:namespace-alias to make it a little bit easier - searching for xsl:namespace-alias will show up examples of its use.
