How does XSLT utilize prefixed attributes from a separate so

Post by **iBall** » Thu Mar 26, 2015 6:07 am

I take an XML file and transform it to a fixed width utilizing XSLT, yet I'm forced to use attributes of a certain prefix. For the transformation to function properly I have to upload my finished XSLT file to a website, run it, and the website produces the necessary fixed width file.
What I want to know is how can I perform the same transformation without uploading the XSLT?
What kind of file (Schema, XSL) must I produce and link, to make sense of these attributes?

For example:

Code: Select all

<!-- note_XML.xml -->    

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



    <note>

      <to>Tove</to>

      <from>Jani</from>

      <heading>Reminder</heading>

      <body>Don't forget me this weekend!</body>

    </note>

XSLT:

Code: Select all

<!-- note_XSL.xsl -->    

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

    <xsl:stylesheet smlns:xsl="http://www.w3.org/1999/XSL/Transform"

        xmlns:xs="http://www.w3.org/2001/XMLSchema" exclude-result prefixes="xs"

        xmlns:joe="urn:com.website/joe" version="2.0">



        <xsl:template match="/">

            <Case joe:separator="&#xd;&#xa;">



                <Tape>

                    <PersonReceiving joe:fixedLength="4">

                        <xsl:value-of select="/note/to"/>

                    </PersonReceiving>



                    <Sender joe:fixedLength="4" joe:align="right">

                        <xsl:value-of select="/note/from"/>

                   </Sender>

                   etc...

                </Tape>

            </Case>

        </xsl:template>

    <xsl:stylesheet>

Notice the 'joe' prefixed attributes, what do I do to make sense of them without having to upload the XSLT and have the server do it for me? I'd prefer to do the work in a separate file versus adding variables/functions to the same note_XSL.xsl stylesheet.

I appreciate your input, thanks.

An xslt transformation would probably do the trick. Here's a small demonstration how to change the text content of elements with the joe:fixedLength attribute (ignoring the seperator and align attributes so far):

Test-Input:

Code: Select all

<Case xmlns:joe="urn:com.website/joe" joe:separator="&#xD;&#xA;">

	<Tape>

		<PersonReceiving joe:fixedLength="4">T</PersonReceiving>

		<Sender joe:fixedLength="4" joe:align="right">J</Sender>

	</Tape>

</Case>

XSL:

Code: Select all

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

<xsl:stylesheet version="2.0"

	xmlns:xsl	= "http://www.w3.org/1999/XSL/Transform"

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

	xmlns:joe	= "urn:com.website/joe"

	exclude-result-prefixes="xs">

	

	<!-- identity transformation as default templates -->

	<xsl:template match="document-node() | element()">

		<xsl:copy>

			<xsl:apply-templates select="attribute() | node()"/>

		</xsl:copy>

	</xsl:template>

	

	<xsl:template match="text() | attribute() | processing-instruction() | comment()">

		<xsl:copy/>

	</xsl:template>

	

	<!-- handling elements with joe:fixedlength attribute -->

	<xsl:template match="*[@joe:fixedLength]">

		<xsl:copy>

			<!-- don't copy any sub-items except the text -->

			<xsl:value-of select="for $i in (1 to (xs:integer(@joe:fixedLength) - string-length(text()))) return ' '" separator=""/>

			<xsl:copy-of select="text()"/>

		</xsl:copy>

	</xsl:template>

	

</xsl:stylesheet>

Output:

Code: Select all

<Case xmlns:joe="urn:com.website/joe" joe:separator="&#xD;&#xA;">

	<Tape>

		<PersonReceiving>   T</PersonReceiving>

		<Sender>   J</Sender>

	</Tape>

</Case

Regards,

Patrik

Thank you for responding Patrik;

So create another XSL and add it as a second transformation, correct?

I'll try that out right now.

Of course you could adapt the existing stylesheet as well by droping the joe-attibutes and directly formatting the values. But I understood that you WANT to use another transformation...

Patrik,
I believe its missing something, I can't get the fixedLength attribute to work; should I have declared the attribute somehow? I'm sorry, I'm quite new to XSL/XML.
And how do we link-up the stylesheets? I went to "Configure Transformation Scenario" and selected "Additional XSLT stylesheets"; is that how its done?

thanks again.

Sorry, but I can't help you since I don't understand what you actually want and my assumptions appear to be wrong.

Regards,
Patrik
