Convert String to XML Document in JavaScript



Saw this example on the jQuery examples page for Ajax:







var xmlDocument = [create xml document];

$.ajax({

url: "page.php",

processData: false,

data: xmlDocument,

success: someFunction

});







How do I take a string like:







var t = '<foo><bar>something</bar></foo>';







And convert that to a XML DOM object? cross-browser?





UPDATE : Please see comments to karim79's answer.

  1. Wrap it in a jQuery object. Then use jQuery's normal DOM manipulation methods on it.

    var t = $('<foo><bar>something</bar></foo>');

    //loop over 'bar' nodes
    t.find('bar').each(function () {
    alert($(this).text());
    });


    If you want to convert it back to a plain string (after modifying it for example) you can do it like so:

    //then convert it back to a string
    //for IE
    if (window.ActiveXObject) {
    var str = t.xml;
    alert(str);
    }
    // code for Mozilla, Firefox, Opera, etc.
    else {
    var str = (new XMLSerializer()).serializeToString(t);
    alert(str);
    }


    EDIT: The $.ajax manual says (on the processData option):


    By default, data passed in to the data
    option as an object (technically,
    anything other than a string) will be
    processed and transformed into a query
    string, fitting to the default
    content-type
    "application/x-www-form-urlencoded".
    If you want to send DOMDocuments, or
    other non-processed data, set this
    option to false.


    So if you're passing a jQuery object to the server, you'll need to set that to true, or omit it altogether (it is set to true by default). Hope that helped.

  2. Just a heads up on calling find - if it's a top level element you need to use filter instead.

    var t = $('<foo><bar>something</bar></foo>');

    //loop over 'foo' nodes
    t.filter('foo').each(function () {
    alert($(this).find('bar').text());
    });

  3. you can use this simple code for convert your xml tags to text

    var temp_var = $("<p/>").append($(your_xml_data)).htML()

Why is this Javascript much *slower* than its jQuery equivalent?

I have a HTML list of about 500 items and a "filter" box above it. I started by using jQuery to filter the list when I typed a letter (timing code added later): $('#filter').keyup( function() { var jqStart = (new Date).getTime(); var search = $(this).val().toLowerCase(); var $list = $('ul.ablist > li'); $list.each( function() { if ( $(this).text().toLowerCase().indexOf(search) === -1 ) $(this).hide(); else $(this).show(); } ); console.log('Time: ' + ((new Date).getTime() - jqStart)); } ); However, there was a couple of seconds delay after typing each letter (particularly the first letter). So I thought it may be slightly quicker if I used plain Javascript (I read recently that jQuery's each function is particularly slow). Here's my JS equivalent: document.getElementById('filter').addEventListener( 'keyup', function () { var jsStart = (new Date).getTime()...

Is it possible to have IF statement in an Echo statement in PHP

Thanks in advance. I did look at the other questions/answers that were similar and didn't find exactly what I was looking for. I'm trying to do this, am I on the right path? echo " <div id='tabs-".$match."'> <textarea id='".$match."' name='".$match."'>". if ($COLUMN_NAME === $match) { echo $FIELD_WITH_COLUMN_NAME; } else { } ."</textarea> <script type='text/javascript'> CKEDITOR.replace( '".$match."' ); </script> </div>"; I am getting the following error message in the browser: Parse error: syntax error, unexpected T_IF Please let me know if this is the right way to go about nesting an IF statement inside an echo. Thank you.
