    xslt-problem with GetMedia

    Hi

    I have this xslt-file:

    --------------------------------------------------------
    <?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: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 ">

    <xsl:output method="xml" omit-xml-declaration="yes"/>
    <xsl:param name="currentPage"/>
    <xsl:template match="/">
        <xsl:value-of select="umbraco.library:GetMedia($currentPage/data[@alias='frontPicture'], 'false')/data[@alias = 'umbracoFile']" />
    </xsl:template>
    </xsl:stylesheet>
    --------------------------------------------------------

    when i test it in the visualizer it works as I want it to - but when I try to save it I get an error:

    --------------------------------------------------------
    (XmlQueryRuntime {urn:schemas-microsoft-com:xslt-debug}runtime)
    at Root(XmlQueryRuntime {urn:schemas-microsoft-com:xslt-debug}runtime)
    at System.Xml.Xsl.XmlILCommand.Execute(Object defaultDocument, XmlResolver dataSources, XsltArgumentList argumentList, XmlWriter writer, Boolean closeWriter)
    at System.Xml.Xsl.XmlILCommand.Execute(IXPathNavigable contextDocument, XmlResolver dataSources, XsltArgumentList argumentList, XmlWriter results)
    at System.Xml.Xsl.XslCompiledTransform.Transform(IXPathNavigable input, XsltArgumentList arguments, TextWriter results)
    at umbraco.presentation.webservices.codeEditorSave.SaveXslt(String fileName, String oldName, String fileContents, Boolean ignoreDebugging)
    --------------------------------------------------------

    What is wrong?? .........

    Hi,

    you have 2 options here:

    1: disable checking for errors upon saving 

    2: use the following code:

    <xsl:if test="$currentPage/data[@alias='frontPicture'] != '' ">
        <xsl:value-of select="umbraco.library:GetMedia($currentPage/data[@alias='frontPicture'], 'false')/data[@alias = 'umbracoFile']" />
    </xsl:if>
    The preview works because you have an active node. Upon saving, you don't have a node to test against, hence the error (Getmedia requires an integer, if nothing present, it's not an integer).
    HTH,
    Peter

    Yeah, you should use the examplecode that Peter wrote in his post.

    Otherwise, you could edit the file outside of Umbraco in some sort of code editor. I myself use Visual Studio all the time.

    Yes, I think Peter's code (sol. 2) is best practice. I always do that way and never have problem.

    Hi Peter [BB], yes follow what Peter D suggested, by having an IF condition around the value-of / GetMedia.

    I wrote a blog post a few weeks ago about how to safely handle the GetMedia calls in XSLT - have a read...

    Cheers, Lee.
