Welcome to the G2 XML to HTML transformer
=========================================

The XSLT stylesheet "G2xml2Html_{version no}.xslt" 
transforms the primarily machine readable G2 XML 
into human readable HTML. 

The HTML page provides a list of all properties 
contained by the G2 item. 

These details are available for each property 
which is represented as XML element:
- the name of the element (property)
- a value of the element, if there is one
- names and values of all XML attributes of the element

Further the HTML pages add hiearchical structures of the G2 item by
- each property is displayed in a box, see a guide to the different 
types and widths of the box lines in the top section of the HTML page.

- coloured regions of the item: the child elements of the root of an 
item have their background in a distinct colour. The first element in 
a region with a new colour defines the scope of this colourcoding.

- the top elements of any coloured region provides a link
to the corresponding documentation of the XML Schema. 
This documentation could be the one of the IPTC web server or
files on your local PC - see below "How to use".

Finally: any major issues with the business logic of G2
which were found in a G2 item are shown in the top region 
of the HTML page.

*** How to use:
Check if these files are available in the same folder on your computer:
- G2xml2Html_{version no}.xslt
- G2xml2html-resources-local.xslt
- G2xml2html-resources-web.xslt

Apply the G2xml2Html_{version no}.xslt stylesheet to an XML instance 
of any G2 item or a G2 News Message. How this is done depends on
the tools available to you: a browser, a XSLT engine, an XML tool.

Accessing documentation:
By default the XSLT stylesheet uses the G2 XML Schema documentation
on the IPTC web server. 
If you want to work offline you can switch to local files.
* Prerequisites are:
- the directory containing the XML instances and the XSLT sheet MUST
be a sibling to the .....\specification directory of the G2 standard.
- the ...\specification directory must contain the folder 
-- XML-Schema-Doc-Core (for items at the Core compatibility level)
-- XML-Schema-Doc-Power (for items at the Power compatibility level)
... with all *.html and *.png files. ZIP packages of these
documentation files can be downloaded from the IPTC web server.

* Next you must edit the XSLT G2xml2Html_{version no}.xslt this way:
The 2 lines:
	<xsl:import href="G2xml2Html-resources-web.xslt"/>
	<!--	<xsl:import href="G2xml2Html-resources-local.xslt"/> -->
must be changed to:
	<!--	<xsl:import href="G2xml2Html-resources-web.xslt"/> -->
	<xsl:import href="G2xml2Html-resources-local.xslt"/>

* now it should work.

If you have any problems with using this XSLT please post to
the NewsML-G2 Yahoo group with its web interface at:
