Hi all,
I now this is more a XSLT issue than Datapower's, but maybe some of you could give some light on this (that seem's pretty basic).
I need the following behavior in a XSLT Transformation in Datapower:
Input text:
| Code: |
AAAAAZZZZZZZ
BBBBBZZZZZZZ
CCCCCZZZZZZZ |
Output text:
| Code: |
_HEADER
AAAAA
BBBBB
CCCCC
_FOOTER |
So I wrote the following XSLT:
| Code: |
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:dp="http://www.datapower.com/extensions"
xmlns:str="http://exslt.org/strings"
xmlns:date="http://exslt.org/dates-and-times"
extension-element-prefixes="dp str date"
>
<dp:input-mapping href="store:///pkcs7-convert-input.ffd" type="ffd"/>
<xsl:output method="text"/>
<xsl:variable name="rowsep" select="'
'"/>
<xsl:variable name="input64" select="dp:binary-encode(/object/message/node())"/>
<xsl:variable name="str" select="dp:decode($input64,'base-64')"/>
<xsl:template match="/">
<!-- Header -->
<xsl:text>_HEADER
</xsl:text>
<!-- Body -->
<xsl:for-each select="str:split($str,$rowsep)">
<xsl:if test="position()!=last()">
<xsl:value-of select="substring(.,1,5)"/>
<xsl:text>
</xsl:text>
</xsl:if>
</xsl:for-each>
<!-- Trailer -->
<xsl:text>_FOOTER
</xsl:text>
</xsl:template>
</xsl:stylesheet> |
But it is generating the following output:
| Code: |
_HEADER
_HEAD
AAAAA
BBBBB
CCCCC
_FOOT
_FOOTER |
I don't understand why every text or value-of tag outside the for-each tag generates strange outputs (or at least I'm not able to find a pattern of what's wrong). As you can see, the header is "partially" repeated, and has no clue the reason of this behavior. Seems that it is modifying a reference.
Could you please give me some hints on where the mistake would be? |

Solved!... It was my fault... I was closed in the idea that was the XSLT that was failing. But I was applying twice the transformation: in the MPG and in the backend. That explains the strange behavior.  |
