tool to validate xml file against custom XML Schema file

[Leona]

Hello all,

does anyone know of a tool, preferably free, preferably on linux, which will take an xml file and validate it against your own custom W3C XML Schema file (.xsd) ??

All help appreciated - it's proving very difficult to find. Failing that, does anyone know how to get the W3C's own online validating engine (XSV, I think it's called) to do the same job? I can't get it to do what I want and I can't really understand the output.

Many thanks in advance....

How about xmllint from libxml?

Depending on what you have on your system, look in /usr/local/bin. Failing that, try http://xmlsoft.org

You can use openjade from cmd line to do this. openjade (http://openjade.sf.net) comes with most major linux distros. type in onsgmls on the cmd line to get more info.

W3C's online validator is merely a web interface to openjade. It passed the input file to openjade, and takes the output and displays it as a webpage. i use the same technique for the docbook validator @ http://validate.sf.net

as far as i know, xmllint only checks if the document is well-formed or not. It does NOT check for the validity of the document against a schema. Please correct if I am wrong. Thanks. Saqib Ali http://validate.sf.net

xmllint can validate against a DTD.

xmllint can validate against a DTD.

That's right, but

--relaxng schema
Use RelaxNG file named schema for validation.

--schema schema
Use a W3C XML Schema file named schema for validation.

are supported, too.

$ xmllint --version
xmllint: using libxml version 20611

But opensp does not support W3C schema.

Thanks for the hint.

Most of my daily work is on RedHat 7.2 and there
we have an xmllint which can only validate against
a DTD. But the xmllint that comes with RedHat 9.0
behaves as describes by you. I will use it !

that is correct. sorry. i should have read the original post more carefully. it must have been very late in the night

sorry.

Two alternative answers:

1) If your W3C XML Schema document is available on the web, you can give the XSV web form both the instance URI and the schema document URI and it will validate for you

2) If not, you can download and install an rpm and run it from the command line

Detailed instructions for both approaches are at [1].
