How to render diff report like its done in the Web Tool

[Huzaifa S]

I am fairly new javascript developer and I trying to figure out something I think will be easy for you to resolve. The code below is doing a diff on two XML documents.
var options = {
"source": srcXML,
"diff": diffXML,
"lang": "xml",
"langdefault": "xml",
"csvchar": ",",
"crlf": false,
"api": "dom",
"jsscope": false,
"braceline": false,
"bracepadding": false,
"braces": "knr",
"compressedcss": false,
"conditional": false,
"content": false,
"context": "",
"diffcomments": false,
"comments": "nocomment",
"difflabel": "new",
"diffspaceignore": false,
"diffview": "inline",
"dustjs": false,
"elseline": false,
"force_attribute": false,
"force_indent": false,
"html": false,
"insize": 4,
"methodchain": false,
"nocaseindent": false,
"objsort": "js",
"preserve": "all",
"quote": false,
"selectorlist": false,
"semicolon": false,
"sourcelabel": "base",
"space": true,
"style": "indent",
"tagmerge": false,
"tagsort": false,
"ternaryline": false,
"textpreserve": false,
"wrap": 80,
"inchar": " ",
"mode": "diff"
};
var pd = prettydiff(options); // returns and array: [beautified, report]

var pretty = pd[0];
var report = pd[1];

the value in 'report' from pd[1] gives me the results I am expecting.

<p>Code type is set to
<strong>markup</strong>.
</p>
<p>
<strong>Execution time:</strong>
<em>25.510 seconds </em>
</p>
<p>
<strong>Number of differences:</strong>
<em>113</em> differences from
<em>81</em> lines of code.
</p>
<p>Accessibility note.
<em> tags in the output represent character differences per lines compared.
</p>

But when I save the output of pd[0] as a XML document, it does not match the report I get when I run the same comparison using the HTML web tool. The HTML web tool is correcting rendering the report. How can I make result saved into pd[0] look the same as report rendered by the online tool. The diff output is not inline either even though I am indicating it in the options passed to pd. I need to make this work in a web app that does not run in the context of a browser or in nodejs.

Can you please provide tips to help me get this working?
