Hello everyone,
Being new to XML i have stuck in the middle of no where while converting the result set of my sql query in HTML format, getting all the data as per the expectation but somehow the XML column is blank in the HTML..
Have a look at the code below...
DECLARE @txtMis VARCHAR(Max)--,
SET @txtMis = '<HTML><Head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title><style type="text/css">
body {
margin: 0px;
padding:25px;
font-family:Arial, Helvetica, sans-serif;
font-size:12px;
color:#454545;
}
</style>
</head>
<BODY bgColor="FFFFFF">'
SET @txtMis = @txtMis
+ '<table width="100%" border="0" cellspacing="0" cellpadding="0" style="border:solid 1px #d5d5d5; border-right:0px none; border-bottom:0px none font-size: 8px;">
<tr>
<td colspan="10" align="center" bgcolor="#f8f8f8" height="28" style="border-bottom:#d5d5d5 solid 1px; border-right:#d5d5d5 solid 1px;"><b>Details of Missing Index on

</tr>

Any help would be appreciated

I tried and failed to run a query that would produce the "Missing Index" option, so I can't confirm that the code below does exactly what you are looking for. It does find and parse the query plan XML for queries in the cache and produces HTML code from that. I had to change a lot of things to get it to do anything for me, so I hope this can at least point you in the right direction.
IF OBJECT_ID('tempdb..#TempTable') IS NOT NULL
DROP TABLE #TempTable

[ObjectDetail] VARCHAR(MAX) NULL,
[BatchXML] XML NULL,
