jQuery Xml parsing what is the problem here?

I have this code where i's like to traverse through all com.abc.db.ConfigInfo row,开发者_开发知识库 and if any of them contains cfgId as 141 alert(cfgName)

Updated

alert(xml);
                        $(xml).find('list com\\.abc\\.db\\.ConfigInfo').each(function()
                        {
                            alert("enter the dragon");
                            if($(this).find('cfgId').text()=="141")  
                            alert($(this).find('cfgName').text()); 
                        }); 

My XML

<list>
<com.abc.db.ConfigInfo>
<cfgId>83</cfgId>
<cfgName>test</cfgName>
</com.abc.db.ConfigInfo>
<com.abc.db.ConfigInfo>
<cfgId>102</cfgId>
<cfgName>cfgname1</cfgName>
</com.abc.db.ConfigInfo>
    </list>

Your code looks correctly to me. But in your xml example you don't have any cfgId as 141. And this is a good reason why you don't get any alert...

Sizzle (the library jQuery uses for .find and its friends) will interpret your "com.abc.db.ConfigInfo" as "node com with classes abc, db and ConfigInfo".

You can try if escaping the dots works ("list com\\.abc\\.db\\.ConfigInfo", double backslash because these are JS strings and you need to escape the backslash) but if possible I suggest you pick tag names without dots. Underscores should work better.

start traversing from root node..

newXml = $.parseXML(xml)// parse your xml
$(newXml).find('list com.abc.db.ConfigInfo').each(function(){                            
if($(this).find('cfgId').text()=="141")                             
alert($(this).find('cfgName').text());                        
 });
