A external application is sending error-xml-files as respond.xml, if an error occures. I try to transform these Messages into a readeble text. But the respond.xml has only error-codes. But I would like to see the real error-message, wich I can find in errors.xml
Is it possible to combine my xslt to errors.xml?

How could I include that errors.mxl to my xslt-File rtest.xsl?

Thank you for your help!

A respond.xml looks abot like this:

Code: Select all

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

<invoice:response xmlns:invoice="abc">

	<invoice:invoice invoice_id="9549">

	</invoice:invoice>

	<invoice:status>

		<invoice:rejected>

			<invoice:error error="101"/>

			<invoice:error error="103"/>

		</invoice:rejected>

	</invoice:status>

</invoice:response>

The errors.xml is like this:

Code: Select all

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

<errors>

    <error_id>101</error_id>

    <message>invalid address</message>

    <error_id>102</error_id>

    <message>invalid amount</message>

    <error_id>103</error_id>

    <message>wrong currency</message>

</errors>

And my xslt-File looks this way:

Code: Select all

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

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">

    <xsl:template match="invoice:status" xmlns:invoice="abc">

        <xsl:if test="invoice:rejected"> Responsetyp: Rejected 

            

            <xsl:for-each

                select="invoice:rejected/invoice:error"> Error: <xsl:value-of select="@error"/>

                <!-- Here  should be the error-message from errors.xml-->

            </xsl:for-each>

            

        </xsl:if>

    </xsl:template>

</xsl:stylesheet>

I have found a solution.
First I had to separate the errors in errors.xml:
<?xml version="1.0" encoding="UTF-8"?>

Code: Select all

<response>

    <errors>

        <message_id>101</message_id>

        <message>invalid address</message>

    </errors>

    <errors>

        <message_id>102</message_id>

        <message>invalid amount</message>

    </errors>

    <errors>

        <message_id>103</message_id>

        <message>wrong currency</message>

    </errors>

</response>

Then in the XSLT I linked the errors.xml:

Code: Select all

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

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">

    <xsl:template match="invoice:status" xmlns:invoice="abc">

        <xsl:if test="invoice:rejected"> Responsetyp: Rejected

            

            <xsl:for-each

                select="invoice:rejected/invoice:error">

                <xsl:variable name="v_error_id" select="@error"/>

                Error_id: <xsl:value-of select="$v_error_id" />

                Error: <xsl:value-of select="document('errors.xml')/response/errors[message_id=$v_error_id]/message"/>

            </xsl:for-each>

                     

        </xsl:if>

    </xsl:template>

</xsl:stylesheet>

Yes, you can use the document function to access data from another file. Note however that you do not necessary need to change the structure of the errors file as you can access the message using the following sibling axis, see for example

Code: Select all


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

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">

  <xsl:template match="invoice:status" xmlns:invoice="abc">

    <xsl:if test="invoice:rejected"> Responsetyp: Rejected

      <xsl:for-each

        select="invoice:rejected/invoice:error">                 

        <xsl:text>&#10;Error: </xsl:text>

        <xsl:value-of select="@error"/>

        <!-- Here  should be the error-message from errors.xml-->

        <xsl:text> </xsl:text>

        <xsl:value-of 

          select="document('errors.xml')/errors/error_id[.=current()/@error]/following-sibling::message[1]"/>

      </xsl:for-each>

    </xsl:if>

  </xsl:template>

</xsl:stylesheet>
