Looking at the stylesheet element I have identified a difference in this version when creating a 'clean' XSLT file:

Umbraco 7 creates:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:msxml="urn:schemas-microsoft-com:xslt" xmlns:umbraco.library="urn:umbraco.library" xmlns:Examine="urn:Examine" exclude-result-prefixes="msxml umbraco.library Examine ">

Where 6.1.5 created:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:msxml="urn:schemas-microsoft-com:xslt" xmlns:umbraco.library="urn:umbraco.library" xmlns:Exslt.ExsltCommon="urn:Exslt.ExsltCommon" xmlns:Exslt.ExsltDatesAndTimes="urn:Exslt.ExsltDatesAndTimes" xmlns:Exslt.ExsltMath="urn:Exslt.ExsltMath" xmlns:Exslt.ExsltRegularExpressions="urn:Exslt.ExsltRegularExpressions" xmlns:Exslt.ExsltStrings="urn:Exslt.ExsltStrings" xmlns:Exslt.ExsltSets="urn:Exslt.ExsltSets" exclude-result-prefixes="msxml umbraco.library Exslt.ExsltCommon Exslt.ExsltDatesAndTimes Exslt.ExsltMath Exslt.ExsltRegularExpressions Exslt.ExsltStrings Exslt.ExsltSets ">

Was able to substitute the function with:

<xsl:variable name="lower">abcdefghijklmnopqrstuvwxyz</xsl:variable>
<xsl:variable name="upper">ABCDEFGHIJKLMNOPQRSTUVWXYZ</xsl:variable>
<xsl:variable name="lcaseauthor" select="translate($currentPage/author,$upper,$lower)]"/>

Is anyone else having issues posting to the forums? I've noticed the listing on the homepage is not showing to what category this post was made nor the author. On several attempts to update this post, the editor fails and in my browser console I see I am getting response code 500 (internal server error).

Hi Thomas,

The EXSLT extensions were removed from core because many of them just didn't work - Here's an issue where it's discussed

There should be a package available at some point that reinstalls them so someone like you can use those that actually did work, if needed. Depending on the way you're using the lowercase() function, there's a couple of alternatives for you to do. Can you show a little more context so we know what you're doing specifically?

Hey Chriztian,

Thanks for your reply. I have found an alternative method, shown below. The need for the lowercase function was in making link URLs all lowercase and for setting the canonical values.

<xsl:variable name="lower">abcdefghijklmnopqrstuvwxyz</xsl:variable>
<xsl:variable name="upper">ABCDEFGHIJKLMNOPQRSTUVWXYZ</xsl:variable>
<xsl:variable name="lcaseNodeWithValue" select="translate(nodeWithValue,$upper,$lower)"/>
<xsl:value-of select="$lcaseNodeWithValue" />

Hey Chriztian, thanks for your reply. The need for the lowercase function had to deal with setting canonical link values for pages as well as keeping well-formed dynamic links in some sections of our site.

After some prompting from Chriztian, we've got around to releasing the EXSLT extensions as a standalone package.

It is available to download from here: http://our.umbraco.org//projects/website-utilities/exslt-redux
