XML or not XML?
I am developing a simple MySQL database editor, and am looking into
creating an PHP/AJAX app as the GUI. A lot of this in new ground, and
much more is dusting off things I haven't used in a while. My question
though involves whether or nor to employ XML. I did some XML a few
years back, but don't typically bother anymore. As I see it XML is
great when I need to have an app with a standard data presentation that
other developers can easily interface. I.E. like a bank statement that
may feed a variety of applications developed by a variety of clients.
However, if I am develo...To XML or not to XML?
Ok, it has been a while since I've needed to make an involved web page.
Coming back on the scene now is a bit confusing, what with all the cool
stuff to use like XML, PHP, MySQL, etc...
So here is my question. I'm in search of a good dynamic way to generate web
pages which separates content from presentation. I am seeking to create a
web site that, to put it succinctly, has a list of users and sets of
information corresponding to each user.
I am familiar with how to do this using PHP, MySQL, and regular old HTML. I
maintain the user database in MySQL and dynamically present it and the
information with PHP. This is very easy to do in terms of coding for it.
But I'm wondering? Is it time for me to switch to the XML with XSL method
instead? Everyone seems to be talking of XML as the end all be all. I've
looked into it, and on the surface, I just can't tell if it's worth it. I
don't really see the benefit. XML is just a "create your own HTML tags" and
then figure out wtf to do with them orgy. Great, so I can write
<dog>Spot</dog>. Whoop de do, that's useless to me unless I write a parser
for it to display it in a user friendly way. And I shouldn't have to write a
parser, there should be standardized ones for certain purposes. But wait,
isn't that what HTML already is? A bunch of <dog>Spot</dog> (figuratively
speaking) with the parsers having been written and mostly standardized

Classic application for XSLT. Start with the identity transformation,
then add a template which matches the ones you want to treat specially
and yields no output. From your description that would be
with the namespaces declared appropriately in the stylesheet.
(That looks like a somewhat unlikely markup design to me, but since I
haven't played with gnucash at all I'm taking your word for it.)

Actually, from the Relax-NG schema for gnucash, it looks like it should
be more like

The fact that some of their elements -- eg <slot> -- aren't in any

But on the point where i read from xml, the VI should check the associated xml schema (.xsd/.dtd). Is there any possibilty to get a pass oder fail if the xml document do/do not correspond to the DTD schema which belong to the xml file?LabVIEW version is 7.1Thanks for answer,shavo

I have a need to validate XML files against both DTDs and XML Schema from

which would then parse and validate foo.xml using the schema or DTD

I have an application that logs in xml.
Assume <xmlLog></xmlLog>. In this element the app logs anything it gets
from foreign hosts. Now if the host sends xml data, the structure of the

cause problems with my log reader, because it assumes that <xmlLog/>
contains non-xml data.
My question is, is there a way to treat the data in the <xmlLog/>
element as non xml data. Something I can do that would treat anything
this element contains as a literal?
Any help or suggestions would be greatly appreciated.

I have an XML Schema A which needs to mapped to another XML Schema B.
Is there any handy tool which I could use to convert from Schema A to
Any related informaiton on this is appreciated.
XML Schema's represent the overall structure of your xml document. So if you
want a different schema, you should create it.
If you have commonality between the two schema's then you should think of
putting that commonality in another schema and import that schema to your
ie. if Schema A and Schema B have common features, create Schema C
import Schema C into both Schema A and Schema B.
about transforming one schema to another, there is the XSLT transformation
which possibly could do this (since XSD is itself an XML document) but i
havent that myself. Stylus Studio is something that you may want to use to
play with this.

...Validating XML against a DTD that is not supplied in the XML Schema
I'm talking the problem of trying to validate whether a rss xml feed
is well formed - i.e corresponds to the DTD and xml schema
Given that rss comes in a number of forms:

* Sometimes a schema is referenced, with namespaces
* Most of the time, no DTD or schemas or namespaces are defined.
My application requires to know whether an rss feed supplied is valid
as there is processing on the data that occurs later.
My orignal tack was to parse the data into objects ( via RSSDigester )
and then apply business logic.

I would like to specify an XML schema that would allow an XML document
to be included within another XML document. The following example
schema gives an idea of what we're trying to achieve
<?xml version="1.0" encoding="UTF-8"?>
<xs:element name="serviceResponse" type="ServiceResponse"/>
<xs:element name="anXMLDocument" type="xs:string"/>
<xs:element name="someOtherData" type="xs:string"/>
The element anXMLDocument would contain an XML data string that would
be parsed against a different XML Schema. The identity of the XML
Schema for parsing anXMLDocument is not known at the time the
ServiceResponse XML is parsed.
Previously when we used DTDs we used inline CDATA wrappers around the
contained XML document to avoid it being parsed. Can we still continue
to use inline CDATA wrappers around the XML data when we parse against
XML schemas? I've tried looking into the XML Schema specs but the
mention of CDATA seems a bit sparse and doesn't seem to answer the

I vageuly remember a standard that allowed for an XML document using one
tag vocabulary to be translated to a diffirent XML document using a
diffirent tag vocabulary using the information provided in a kind of
dictionary XML pointed to in an URL present in the original XML file. I
am very interested in trying it out for various applications, but I
can't find anything on the internet about it, since I don't remember
it's name, only the general appearance. Can anyone help me with this?
What I remember, approximately:
The idea is that you have one XML file, in which the namespace is
defined in the standard way, using an URI. The URI, however, is pointing
to an online XML file. For example:
This dictionary.xml then contains, for example:
So a program wishing to convert the original XML to, say format2, would
end up with the following XML:

View the xml file using IE or Mozilla -- they provide an appealing,
