error when loading dai-debt.xml

[SmartLayer]

Access debt-dai.xml

Observe the IFRAMEs are empty and there is an error

Uncaught ReferenceError: loadIframe is not defined.

Later I realised that the debugger assumes the JS fiel to be in the same places as the TokenScript XML file, while I put the debuger (both xsl and js files) into a subfolder, hance the <script src="…" didn't work.

Suggested workaround:

In this version:

https://alphawallet.github.io/TokenScript-Examples/examples/AAVE/debt-dai.xml

I put JavaScript inside the xslt file:

                        <script type="text/javascript" charset="utf-8">
//<![CDATA[
function loadIframe(){
        var iframes = document.getElementsByTagName("iframe");
        for(var i=0; i<iframes.length; i++){
                var iframe = iframes[i];
                var textContent = iframe.textContent;
                var wrapper = document.createElement('div');
                wrapper.innerHTML = textContent;
                
                iframeContentDocument = iframe.contentDocument || iframe.contentWindow.document;
                iframeContentDocument.write(wrapper.innerHTML);
                iframe.textContent = "";
        }

}
//]]>
                </script>

Do you accept this as a solution?

Yes we can do that I kept it separate for code readability. Letter if we include more debugging feature the code may extend.

Does entity reference work in XSLT file? I think it might does. If it does, you should be able to

1. Save a .js file with the following:

//<![CDATA[
function loadIframe(){
        var iframes = document.getElementsByTagName("iframe");
        for(var i=0; i<iframes.length; i++){
                var iframe = iframes[i];
                var textContent = iframe.textContent;
                var wrapper = document.createElement('div');
                wrapper.innerHTML = textContent;
                
                iframeContentDocument = iframe.contentDocument || iframe.contentWindow.document;
                iframeContentDocument.write(wrapper.innerHTML);
                iframe.textContent = "";
        }

}
//]]>

2. refer to them as an entity inside the <script>…</script>?

I'm not sure if entity dereference works on the web, but if it does, it would be great.

Hi Weiwu, 1. Above issue is already resolved. no need of using entity reference for that. Here is the solution. ``` <script type="text/javascript" charset="utf-8"> <![CDATA[ function loadIframe(){ var iframes = document.getElementsByTagName("iframe"); for(var i=0; i<iframes.length; i++){ var iframe = iframes[i]; var textContent = iframe.textContent; var wrapper = document.createElement('div'); wrapper.innerHTML = textContent; iframeContentDocument = iframe.contentDocument || iframe.contentWindow.document; iframeContentDocument.write(wrapper.innerHTML); iframe.textContent = ""; } } ]]> </script> ``` 2. Tried to run the XSLT debugger on Firefix but the XSLT engine of FF does not understand the entity reference where as Chrome's XSLT engine understands it. i.e. Below code fetches the HTML content from the file debt-table.en in Chrome but not in FireFox, So there is no content to write to iframe in case of FF. XSLT: ``` <xsl:for-each select="html:body"> <xsl:copy-of select="."/> </xsl:for-each> ``` XML: ``` <body> &debt-table.en; &credit-table.en; </body> ``` FF has below settings like Chrome to run the XSLT locally. i. Type about:config in adress bar and hit Enter key. Accept the warnings. ii. search - privacy.file_unique_origin and turn this to false. I am still checking ways to make it work on FF, Chrome seems best till then. Thanks

FF has below settings like Chrome to run the XSLT locally.

Which is true?

• FF categorically doesn't recognise entity reference ;
• FF doesn't recognise entity reference when it's served on the web.

Yeah, will try to get by with Chrome for now. FYI we will not always be using entity references - we wanted to allow either entity reference or Object/Manifest since 1.5 years ago but never got around to implemente support for loading views from there.

Hi Weiwu, As per my initial findings, in a way both seems true in case of FF while dealing with XML files. I will update you if I found more information. You can also check this link - https://bugzilla.mozilla.org/show_bug.cgi?id=69799 1. When I loaded XML without styleSheet(XSLT), the <style/> and <body/> are empty. that means it ignored those entity references. See the highlighted part in below image. *FF browser:* [image: https://user-images.githubusercontent.com/20576109/89681057-ccb05100-d911-11ea-92a3-3e8554c9a869.png] 2. When I loaded XML with styleSheet(XSLT), the result was the same, and Network tab also did not loaded those external files. *But here Chrome's behaviour is different and loaded those external files.* You can also see the same in the Network tab. *Chrome browser: * [image: https://user-images.githubusercontent.com/20576109/89681176-084b1b00-d912-11ea-956b-187868377f8b.png] Thanks,

Hi Weiwu,

The original issue 1 here is resolved and committed changes to - https://github.com/darakhbharat/TokenScript-debugger

Now you only need to take ts-debugger.xsl file which also has required JS code.

Now regarding FF one more stackoverflow thread says that right now external entity not supported in FF.
