how to use dynamic custom xml parameter?

    Hi,

    I wish to pass custom xml variable ("imgpath" in this case) but I don't know how to
    use it inside xml.

    Code
    embedpano({swf:"krpano.swf", xml:"xml.xml", target:"krpano", vars:{imgpath:"http://localhost"}});

    I know in the xml action I can use it using "get(imgpath)" but I need to use it in the panorama image
    url attribute - <cube url="get(imgpath)/1/pano_%s_%v_%u.jpg" />

    Is this possible or do I have to use actions?

    Any comments would be appreciated.

    Hi,

    first - the passed 'vars' will be passed to the viewer AFTER parsing the xml - that means when using trying to use the passed variables for url paths it would be too late. To bypass this you could need to load a second xml - or use 'null' as xml parameter and specific an onstart event to load the first xml.

    e.g.

    Code
    embedpano({xml:null, ..., vars:{onstart:"loadpano(pano.xml);", imgpath:"..."}});


    second - for using variables in url paths, placeholders can be used (using get() is not possible there) - see here:
    https://krpano.com/docu/xml/#urlplaceholders

    e.g.

    Code
    url="%$imgpath%/..."

    It doesn't appear to be a specific enough reference and it appears that you are trying to set some base url for select image paths. While you should use the basepath ( https://krpano.com/docu/html/#basepath ) parameter during embedding, since you may run into some cross domain issues, you could try storing your variable information in a data element and referencing that ( https://krpano.com/docu/xml/#data ).

    Thank you cgspicer,

    I haven't tried it yet but I believe Klaus' answer seems to solve the problem!
