How to see message by using <xsl:message terminate="yes" in XSLT mapping

[thorsten73]

Hi all,

I have a problem with an XSLT mapping in the Integration Suite:

I want to check for the existence of some mandatory fields in the mapping and, if they are missing, abort the mapping and throw an exception.

Normally, this works using the instruction `<xsl:message terminate="yes">Exception Text</xsl:message>`.

The mapping is aborted in the Integration Suite, but I can't find my message "Exception Text" anywhere. I can only see the error message "Processing terminated by xsl:message at line 5 in XSLTMapping1.xsl," but not my message.

Does anyone know how to see the message in the log?
Otherwise nobody can't see the reason for the cancellation of the mapping.

Kind regards
Thorsten

Why not use the XML validator function for this type of thing?

You had stated "I want to check for the existence of some mandatory fields in the mapping and, if they are missing, abort the mapping and throw an exception." which I would consider schema validation.

Oh, sorry. That was my fault. I didn't describe my problem correctly.
We want to check the content of an XML document, not the structure.

Hi,

here a solution which is working fine in Integration Suite. The mapping is interrupted and the error message is visible in the log.

Thererfore you can use the error function available since XSLT 2.0.

Example: <xsl:value-of select="error(QName('http://www.w3.org/2005/xqt-errors','error:err0815'), 'This is a test exception!')"/>

You can find a descrition of this function here: https://www.w3.org/TR/xpath-functions-31/#func-error

If you use this functionality you can see the error message in monitoring:

net.sf.saxon.trans.UncheckedXPathException: This is a test exception!

BR,
Thorsten

Thanks, it helped me

Is it possible to use XML validator for validating content of an XML message? I think it can only be used for schema validation, not for checking if the right content was sent.

I got the following response from SAP to this topic:

Upon checking with our dev experts, the CPI XSLT mapping uses Saxon Library for providing XSLT transformations. However, Saxon doesn't output by xsl error message default to the logs. For more information, kindly refer to the following documents:
