Check XML file against XSD? Via XSLT?

[Former Member]

Hello,

we´re using a 6.20 system (XI not available) and want to check XML files against a XML-schema definition file (xsd).

Is there a function in 6.20 available for this? Is it possible to use "CALL TRANSFORMATION" for it? I´ve seen other XSLT parser in the internet which are able to check a source XML against an XSD before transforming it to the result XML.

But is this possible with an 6.20 system?

Thank you for your help,

best regards,

Stefan

XSLT processor is available since basis 6.10, so you can CALL TRANSFORMATION.

you can check these threads for how to validate xml against xsd

Hello Sergey,

yes, I know that it is available on my system. But how can I use this to validate a XML file?

Hello Raja,

thank you for this threads which describe a spolution. Unfortunately it works only for DTD, but not for XSD. is there any possibility to validate a XML against a XSD file?

if you already have a XSLT program which can do this job. create the same in SAP environment - SE80

and then use the stt as below.

CALL TRANSFORMATION (`<name of the xslt which can do the validateion`)

SOURCE XML = <source xml the one to be validated>

RESULT XML xml_out.

xml_out is the variable to receive the results.

Hi Raja,

I have similar situation. I tried to save the schema in SE80 before I do the CALL TRANSFORMATION, but SAP does not like the <xsd:schema> tags, Here is the error message I got when I tried to activate the XSLT program.

Illegal root element 'xsd:schema'.

Please if know any work around for this.

Thanks,

Hello,

unfortunately I do not have a XSL-file which can be used to validate a XML against a XSD-Schema (with CALL TRANSFORMATION). If you have one, can you send it to me, please?

Here is the sample XML and the schema.

XML:

<?xml version="1.0" encoding="UTF-8"?>

<book isbn="0836217462">

<title>

</title>

<author>Charles M. Schulz</author>

<character>

<name>Snoopy</name>

<friend-of>Peppermint Patty</friend-of>

</character>

<character>

<name>Peppermint Patty</name>

<since>1966-08-22</since>

<qualification>bold, brash and tomboyish</qualification>

</character>

</book>

XSD:

<?xml version="1.0" encoding="utf-8"?>

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">

<xs:element name="book">

<xs:complexType>

<xs:sequence>

maxOccurs="unbounded"/>

<xs:element name="since" type="xs:date"/>

<xs:element name="qualification" type="xs:string"/>

</xs:sequence>

</xs:complexType>

</xs:element>

</xs:sequence>

<xs:attribute name="isbn" type="xs:string"/>

Hello Suman,

as far as I can see you´ve posted the XSD file. This will of course not work for CALL TRANSFORMATION (which expects an XSLT file). Or do I misunderstand here something!?

Hello Raja,

this web-log is about nearly the same problem. Unfortunately it is only working for schematron XML specifications; but this is no solution for W3C XML schema.

Hi Stefan,

I know this off course don't work for the validation. I think Raja's solution mislead me in believing that we can use the SE80 stylesheet tool and the CALL TRANSFORMATION for the purpose of validation.

Now I have concluded that we can't use CALL TRANSFORMATION for the validation purposes. I have created a OSS Note to SAP, hopefully I may get some answer from them.

Thanks,

Hi All,

Here is the reply I got from SAP OSS.

"No, there is no schema validator integrated in the ABAP server (not even in the current release)."

I guess we should find a alternative way at this point.
