I have to read the encoding and version from xml document.

<?xml version="1.0" encoding="UTF-8"?>
<note>
<to>Tove</to>
<from>Jani</from>
<heading>Reminder</heading>
<body>Don't forget me this weekend!</body>
</note>

i.e; encoding should return as UTF-8 and version as 1.0

Input will be valid xml document.

Please help

The Java XML parser that ColdFusion uses exposes that information via getEncoding() and getVersion(). This'll work on ColdFusion, but not on Lucee or Railo.

    <cfsavecontent variable="foo">
    <?xml version="1.0" encoding="UTF-8"?>
        <note>
            <to>Tove</to>
            <from>Jani</from>
            <heading>Reminder</heading>
            <body>Don't forget me this weekend!</body>
        </note>
    </cfsavecontent>

    <cfset xml = XMLParse(trim(foo))>

    <cfdump var="#{
        encoding: xml.getEncoding(),
        version: xml.getVersion()
    }#">

Tested on ColdFusion 10 & 11.

You can convert the xml to string and then do regular expression to get the version and encoding. 

<cfsavecontent variable="foo">
<?xml version="1.0" encoding="UTF-8"?>
    <note>
        <to>Tove</to>
        <from>Jani</from>
        <heading>Reminder</heading>
        <body>Don't forget me this weekend!</body>
    </note>
</cfsavecontent>

<cfset xml = XMLParse(trim(foo))>   
<cfset xmlString = ToString(xml)>


<cfset Version = REMatchNoCase("version=""(.+?)""", xmlString) >
<cfset version = REMatch("(?s)"".*?""", Version[1]) >
<cfset version = replace(version[1],'"',"","all") > 
<cfdump var="#version#">


<cfset encoding = REMatchNoCase("encoding=""(.+)""", xmlString) >
<cfset encoding = REMatch("(?s)"".*?""", encoding[1]) >
<cfset encoding = replace(encoding[1],'"',"","all") >   
<cfdump var="#encoding#">
