How to avoid spawning new lines when processing?

[Alan Wanwierd]

I have a simple stylesheet who's aim is to simply convert attributes from uppercase to lowercase, without changing any of the values in the data.

However, when I run the transformation any 
 values get pre-pended by a & #13;...
so this:

<?xml version="1.0" encoding="UTF-8"?>
<document>
 <element STRINGVALUE="First line text &#10; SecondLine"/> 
</document>

translated by the following:

<?xml version="1.0" encoding="UTF-8"?>
    
<xsl:stylesheet
    version="1.0"
    xmlns:xalan="http://xml.apache.org/xslt"
    exclude-result-prefixes="xalan" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" encoding="UTF-8" indent="yes" xalan:indent-amount="2" doctype-system="wcs.dtd"/>
<xsl:strip-space elements="*"/>
 
<xsl:variable name="lowercase" select="'abcdefghijklmnopqrstuvwxyz'" />
<xsl:variable name="uppercase" select="'ABCDEFGHIJKLMNOPQRSTUVWXYZ'" /> 
  
  <!--======================================================================-->
  <!--                          The Root Element                            -->
  <!-- The "Root Element" section specifies which template will be          -->
  <!-- invoked first thus determining the root element of the result tree.  -->
  <!--======================================================================-->
 
  <xsl:template match="/">
  <xsl:call-template name="document"/>
  </xsl:template>
 
  <!-- Newly-defined element template -->
  <xsl:template name="document">
  <import>
  <xsl:for-each select="//document">
  <xsl:call-template name="elements"/>
  </xsl:for-each>
  </import>
  </xsl:template>
  
  <xsl:template name="elements">
  <xsl:for-each select="*">
  <xsl:element name="{name()}">
  <xsl:call-template name="attributes" />
  </xsl:element>
  </xsl:for-each>
  </xsl:template>
  
  <xsl:template name="attributes">
  <xsl:for-each select="@*">
  <xsl:attribute
  name="{translate(name(), $uppercase, $lowercase)}">
  <xsl:value-of select="." />
  </xsl:attribute>
  </xsl:for-each>
  </xsl:template>
 
  <!-- Identity transformation template -->
  <xsl:template match="*|@*|comment()|processing-instruction()|text()">
    <xsl:copy>
      <xsl:apply-templates select="*|@*|comment()|processing-instruction()|text()"/>
    </xsl:copy>
  </xsl:template>
</xsl:stylesheet>
 
    

Produces:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE import SYSTEM "wcs.dtd">
<import>
  <element stringvalue="First line text &#13; &#10;SecondLine"/>
</import>    

Any ideas why this is happening and how I can stop it?

Thanks

ETA: Grrrrr Jranch has parsed my XML samples!!! So I've added spaces so you can see what I'm talking about!

That is quite strange. Why don't you have a look at Section 3.3.3 of the XML Recommendation. It's headed "Attribute-Value Normalization" and it deals with what a parser is supposed to do to an attribute. I don't see it mentioning inserting 
 characters anywhere, so what you describe looks wrong to me. It even refers to section 2.11, which talks about removing 
 characters. And you certainly aren't inserting them in your transformation, not that I can see anyway.

(If you want the forum to not interpret your & characters, you have to escape them as & when you post.)
