    Hi,

    I yesterday I upgraded from 4.8.0 to 4.8.1 and everything seem to work fine and had no problems, but i have come in this morning to find xslt parsing errors all over my website and when I go to create a new xslt it gives me an error and when i go to edit and save a already saved xslt file it gives me the followig error.

    I have do the Lucene work around but still not working...im new to umbraco as well

    any help would be greatly appreciated

    Hi Michael,

    Double-check that you didn't overwrite your "/config/xsltExtensions.config" file.  It could be missing an entry? or it could be referencing something that no longer exists? (Not sure what that might be)

    Which uComponents XSLT extensions are you using?

    Thanks, Lee.

    Hi Lee,

    The file config/xsltExtensions.config is emtpy!!!

    I dont have a backup......I'm not sure what extensions I was using, but nothing special as I have added anything in, if that makes sense.

    Below is an example xslt

    <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE xsl:stylesheet [ <!ENTITY nbsp "&#x00A0;"> ]>
    <xsl:stylesheet
     version="1.0"
     xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
     xmlns:msxml="urn:schemas-microsoft-com:xslt"
     xmlns:content="http://purl.org/rss/1.0/modules/content/"
     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" xmlns:tagsLib="urn:tagsLib" xmlns:BlogLibrary="urn:BlogLibrary"
     exclude-result-prefixes="msxml umbraco.library Exslt.ExsltCommon Exslt.ExsltDatesAndTimes Exslt.ExsltMath Exslt.ExsltRegularExpressions Exslt.ExsltStrings Exslt.ExsltSets tagsLib BlogLibrary" xmlns:addthis="http://www.addthis.com/help/api-spec">


    <xsl:output method="xml" omit-xml-declaration="yes"/>


    <xsl:param name="currentPage"/>

    <xsl:template match="/">
    <xsl:variable name="MyFeed" select="umbraco.library:GetXmlDocumentByUrl('http://blog.libertycomms.co.uk/category/uncategorized/feed')" />

     <xsl:for-each select="$MyFeed/rss/channel/item[1]">   
      <h1><xsl:value-of select="title" /></h1>
      <span class="blogDate"><xsl:value-of select="umbraco.library:FormatDateTime(pubDate, 'MMMM d, yyyy')"/></span>
      <p><xsl:value-of select="umbraco.library:TruncateString(content:encoded, number(420), '...')" disable-output-escaping="yes" /></p>
      <p>&nbsp;</p>
      <a href="{link}" class="readMore">read more <img src="images/x.jpg" border="0" /></a>
     </xsl:for-each>


    </xsl:template>
    </xsl:stylesheet>

    Hi Michael,

    Looking at your XSLT, I can see references to "tagsLib" and "BlogLibrary" (nothing for uComponents?)

    Try using this for your "xsltExtensions.config" file:

    <?xml version="1.0" encoding="utf-8" ?>
    <XsltExtensions>
        <ext assembly="umbraco.editorControls" type="umbraco.editorControls.tags.library" alias="tagsLib" />
        <ext assembly="Runway.Blog" type="Runway.Blog.BlogLibrary" alias="BlogLibrary" />
    </XsltExtensions>

    Cheers, Lee.

    There must be other XSLT macros using other extensions?  It would be a case of going through each one checking what is missing.

    On the front-end, try adding "?umbDebugShowTrace=true" to the URL - scroll down to see what the error messages are.

    Cheers, Lee.

    Re: blank XSLT.  Issue there is that an empty file is not a valid XSLT file - hence an error.

    Hi Lee,

    All the xslt have been created from a clean template in Umbraco so struggling to think what other extensions one could be using. Using the umbDebugShowTrace=true doesnt display anything either.

    Do you have any other suggestions?? Thanks for all your help

    Regards

    Check the /bin folder for a file called "Runway.Blog.dll", if that isn't there - then you'll need to remove the references from all your XSLT files and xsltExtensions.config.

    In your XSLT files, find the line:

    xmlns:BlogLibrary="urn:BlogLibrary" 

    Then from "exclude-result-prefixes", remove the "BlogLibrary" reference.

    In your xsltExtensions.config file, remove this line:

    <ext assembly="Runway.Blog" type="Runway.Blog.BlogLibrary" alias="BlogLibrary" />

    Good luck!

    Cheers, Lee.
