Re: [xsl] template to convert all attributes' name to lowercase

2009-05-28 04:55:06
thank you Xmlizer! In the file, one element just have one attribute of
the certain name. I just need to standlize case of name otherwise the
workflow designer rejects to open the file.
Still thank you very much!

Well
Well

The answer is more or less the one proposed by Mike

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

   <xsl:template match="*">
       <xsl:element name="{lower-case(name())}" namespace="{namespace-uri()}">
           <xsl:apply-templates select="@* | node()"/>
       </xsl:element>
   </xsl:template>

   <xsl:template match="@*">
       <xsl:attribute name="{lower-case(name())}"
namespace="{namespace-uri()}">
           <xsl:value-of select="."/>
       </xsl:attribute>
   </xsl:template>

</xsl:stylesheet>

Buy anyway, you have to take care about the fact that if you have
attribute with name that only differ by case, you might end up being
surprise by the result

I hava a task to convert all attributes' name in a xslt file
to lowercase. Actually I don't know whether it's a xslt file.

It's not an XSLT file, it's a stylesheet written in an obsolete Microsoft
language (often called WD-xsl) that was based on an early draft of XSLT,
with Microsoft additions and deletions.

It looks strange, like this:
<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/TR/WD-xsl";>
      <xsl:template match=" / ">
              <HTML>
                      <BodY bgColor="#c0c0c0" Class="screen"
FNSType="SINGLEPAGESCREEN"
id="FNSScreen">
                      //many html things go here.
                      </BodY>
              </HTML>
      </xsl:template>
</xsl:stylesheet>

I'm a novice of  xslt and have only two days to finish this task.

Usually if a task is urgent and the user is a novice I reckon the best
advice I can give is "don't even attempt it, you will only make a mess of
it". However this one is fairly easy. I suspect you want to change the
element names to lower-case too? That's essentially a modified identity
stylesheet:

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

 <xsl:template match="*">
   <xsl:element name="lower-case(name())" namespace="{namespace-uri()}">
     <xsl:apply-templates select="@* | node()"/>
   </xsl:element>
 </xsl:template>

 <xsl:template match="@*">
   <xsl:attribute name="lower-case(name())" namespace="{namespace-uri()}">
     <xsl:value-of select="."/>
   </xsl:element>
 </xsl:template>

</xsl:stylesheet>

That solution uses XSLT 2.0. If for some reason you have to use XSLT 1.0,
you can replace

lower-case(X)

by

translate(X, 'ABCDE....Z', 'abcde....z')
