Use JQuery to extract textual value of xml element called "Title" in IE 8
I've written a search service based around Solr to index a database of objects called clips. The search service returns search resu开发者_如何学Pythonlts formatted using the OpenSearch atom extensions formats. Clips have various properties, ClipID and Title are the two properties relevant to my question.
I have written a very simple JavaScript program using jquery which invokes the search service asynchronously in the background and populates a table with the ClipId and Title values. The program works fine on Chrome, Safari and FF. However, on IE, it simply fails to parse the value of the Title attribute. It is as if "Title" is a reserved XML tag name and jQuery on IE simple can't find it.
Here is the extract from my JavaScript program:
// Ajax call to the search service over HTTP.
var doSearch = function(){
var query = "Title:" + $("#searchQuery").val() + "*";
$.ajax({
url : "/quantel/search/select" ,
data:{q:query},
error:function(request,status,error){
alert(request + "," + status + "," + error);
},
dataType: "text/xml",
success:function(data,status,request){
// Clear the data table.
$("#searchResults").dataTable().fnClearTable();
// Search for all clip entries in the XML document.
$(data).find("entry").children("content").each(function(index,element) {
var clipID= $(element).children("ClipID").text();
var title = $(element).children("Title").text();
// Add the clip id and title to the table.
$("#searchResults").dataTable().fnAddData([clipID,title]);
});
}
});
};
And here is a sample of search results that I am trying to parse. As you can see the Content tag contains a Title tag, yet, IE simply can't find it.

dataType
option of the $.ajax
call has an invalid value. It should be xml
. See http://api.jquery.com/jQuery.ajax
In your case with an invalid data type IE parses the content as HTML, so the title
element is moved into the head
element.
Also MIME-type of the response should be text/xml
. If you need to keep some other MIME type, you can parse an XML response in the way described here: http://docs.jquery.com/Specifying_the_Data_Type_for_AJAX_Requests
The title should be in different namespace. You can try
$(elment).find('atom\:Title').text();
On iPad , can't try it now.
