Recently I've implemented XSLT that transforms any XML into the HTML tree view represented as nested unordered lists. Here is simplified version of this XSLT:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="html" indent="no"/>
<xsl:strip-space elements="*"/>
<xsl:template match="/">
<html>
<body>
<xsl:apply-templates select="." mode="render"/>
</body>
</html>
</xsl:template>
<xsl:template match="/" mode="render">
<div>
<ul>
<xsl:apply-templates mode="render"/>
</ul>
</div>
</xsl:template>
<xsl:template match="*" mode="render">
<li>
<span>
<xsl:value-of select="local-name()"/>
</span>
<div>
<xsl:if test="./text()">
<span>
<xsl:value-of select="translate(./text(),' ',' ')"/>
</span>
</xsl:if>
<xsl:if test="count(child::*)>0 or count(attribute::*)>0">
<ul>
<xsl:apply-templates select="@*" mode="render"/>
<xsl:apply-templates select ="*" mode="render"/>
</ul>
</xsl:if>
</div>
</li>
</xsl:template>
<xsl:template match="@*" mode="render">
<li>
<span>
<xsl:value-of select="local-name()"/>
</span>
<div>
<span>
<xsl:value-of select="translate(.,' ',' ')"/>
</span>
</div>
</li>
</xsl:template>
</xsl:stylesheet>
Note that this XSLT does not depend on XML schema. So it can be applied to any XML. For instance given input XML
<Catalog xmlns="somenamespace">
<CatalogName>First catalog</CatalogName>
<Products>
<Product id="p1">
<Name>Some product</Name>
<Description>foo</Description>
</Product>
<Product id="p2">
<Name>Another product</Name>
<Description>bar</Description>
</Product>
</Products>
</Catalog>
will create desired tree view
<html>
<body>
<div>
<ul>
<li>
<span>Catalog</span>
<div>
<ul>
<li>
<span>CatalogName</span>
<div>
<span>First catalog</span>
</div>
</li>
<li>
<span>Products</span>
<div>
<ul>
<li>
<span>Product</span>
<div>
<ul>
<li>
<span>id</span>
<div>
<span>p1</span>
</div>
</li>
<li>
<span>Name</span>
<div>
<span>Some product</span>
</div>
</li>
<li>
<span>Description</span>
<div>
<span>foo</span>
</div>
</li>
</ul>
</div>
</li>
<li>
<span>Product</span>
<div>
<ul>
<li>
<span>id</span>
<div>
<span>p2</span>
</div>
</li>
<li>
<span>Name</span>
<div>
<span>Another product</span>
</div>
</li>
<li>
<span>Description</span>
<div>
<span>bar</span>
</div>
</li>
</ul>
</div>
</li>
</ul>
</div>
</li>
</ul>
</div>
</li>
</ul>
</div>
</body>
</html>
The problem is that the structure of input XMl has been changed. In fact now it looks like a collection of XML documents wrapped within some root node. See example below:
<Catalogs xmlns="somenamespace">
<Catalog>
<CatalogName>First catalog</CatalogName>
<Products>
<Product id="p1.1">
<Name>Some product</Name>
<Description>foo</Description>
</Product>
<Product id="p1.2">
<Name>Another product</Name>
<Description>bar</Description>
</Product>
</Products>
</Catalog>
<Catalog>
<CatalogName>Second catalog</CatalogName>
<Products>
<Product id="p2.1">
<Name>Some product</Name>
<Description>hoho</Description>
</Product>
<Product id="p2.2">
<Name>Strange product</Name>
<Description>bar</Description>
</Product>
</Products>
</Catalog>
...
</Catalogs>
The requirement is that the output should be shown as a tree of "merged" collection where all different values are concatenated with a comma. See desired output:
<html>
<body>
<div>
<ul>
<li>
<span>Catalog</span>
<div>
<ul>
<li>
<span>CatalogName</span>
<div>
<span>First catalog, Second catalog</span>
</div>
</li>
<li>
<span>Products</span>
<div>
<ul>
<li>
<span>Product</span>
<div>
<ul>
<li>
<span>id</span>
<div>
<span>p1.1, p2.1</span>
</div>
</li>
<li>
<span>Name</span>
<div>
<span>Some product</span>
</div>
</li>
<li>
<span>Description</span>
<div>
<span>foo, hoho</span>
</div>
</li>
</ul>
</div>
</li>
<li>
<span>Product</span>
<div>
<ul>
<li>
<span>id</span>
<div>
<span>p1.2, p2.2</span>
</div>
</li>
<li>
<span>Name</span>
<div>
<span>Another product, Strange product</span>
</div>
</li>
<li>
<span>Description</span>
<div>
<span>bar</span>
</div>
</li>
</ul>
</div>
</li>
</ul>
</div>
</li>
</ul>
</div>
</li>
</ul>
</div>
</body>
</html>
Note that XSLT still must be "schema free". I'm stuck on this issue. The only one solution i see is to use msxsl:script. But it is not desirable since in this case XSLT may not work outside my application.
Any ideas?
