View the xml file using IE or Mozilla -- they provide an appealing,
aesthetic looking layout with collapse/expanding of contents of elements.

If you decide to use XSLT (if, because the first approach above is really
what one needs in order to view an xml file), you need to run the identity
transformation, but specify:

indent="yes"

for the xsl:output element.

Re: XML to XML Transformation

Dimitre,
Thanks for your response. My problem is I have to use this XML file as
input to be processed by an application I am writing. It would be much
easier if I could read a line of input which contained a start tag, the
value, the end tag instead of having to parse a 300+ character line
looking for all the various tags used. I looked up 'identity
transformation' in the XML books I have, Handbook 4.0 and Definitive
XML, and couldn't find a reference. Could you be a little more
specific. Sorry for being a pest.

The identity transform is defined in the XSLT spec
(http://www.w3.org/TR/xslt#copying):

"For example, the identity transformation can be written using xsl:copy as
follows:
<xsl:template match="@*|node( )">
<xsl:copy>
<xsl:apply-templates select="@*|node ()"/>
</xsl:copy>
</xsl:template>"

Therefore this transformation:

<xsl:styleshe et version="1.0"
xmlns:xsl="http ://www.w3.org/1999/XSL/Transform">

<xsl:output omit-xml-declaration="ye s" indent="yes"/>

<xsl:template match="@* | node()">
<xsl:copy>
<xsl:apply-templates select="@* | node()"/>
</xsl:copy>
</xsl:template>

</xsl:stylesheet>

when applied (with Saxon 6.5.3) on this source.xml:

<car><make>ford </make><color>red </color><year>200 1</year></car>

produces this result:

<car>
<make>ford</make>
<color>red</color>
<year>2001</year>
</car>

Then you need a pretty printer/beautifier/code reformatter rather than a
transformation tool! Basically any reasonable XML editor provides such a
feature, e.g. JEdit with the XML plugins.

No, I can't recognise where XSL might make sense in your scenario.

Then it doesn't have to be human readable as stated in your original
posting but rather machine readable what makes a *huge* difference!

Why not just use a standard XML parser like Xerces, Saxon, ... and access
the file using DOM or SAX APIs? Either I am missing some crucial aspect or
you are lacking basic parsing knowledge.

Dimitre,
Thank you so very much. With you help the sun is starting to peek
through these XML clouds :-)

Re: XML to XML Transformation

Basically, you can simply open your XML file in browsers supporting XML
such as IE and you would be able to see the XML formatted properly as
TAGS.

But, if you want to have the XML formatted in a particular style as
paragraph and so on,, you would need to develop/build an XSL file, and
do a transformation by applying XSL on top of XML in order to make it
formatted and human readable.

But I think using a browser is the simplest idea. You can collapse
everything you don't want to see.
