How to remove all XML nodes having specified attributes.

[viKasm]

Hi All,

I want to remove all XML nodes having specified attributes.

my XML:

var strText='<p>My First Line.<br /><span ignoreIn="true">Ignore in true.</span>My Second Line.<br /><span ignoreIn="false">Ignore <span ignoreIn="true">Ignore in true.</span>in false.</span>My Third Line.<br /><span ignoreIn="true">Ignore in true.</span>My Fourth Line.<br />My Last Line.</p>';

I want an output like: '

<p>My First Line.<br />My Second Line.<br /><span ignoreIn="false">Ignore in false.</span>My Third Line.<br />My Fourth Line.<br />My Last Line.</p>

Can any one of you please help me to get the javascript code?

basically, load the string as XML, get all <span>s, remove those who have an ignoreIn attribute, which is set to "true".

Thanks Dormilich for your quick reply!

I have written a code as follows:

strText = '<p>My First Line.<br /><span ignoreIn="true">Ignore in true.</span>My Second Line.<br /><span ignoreIn="false">Ignore <span ignoreIn="true">Ignore in true.</span>in false.</span>My Third Line.<br /><span ignoreIn="true">Ignore in true.</span>My Fourth Line.<br />My Last Line.</p>';
//
function loadXMLString (p_strText) {
if (window.DOMParser) {
parser = new DOMParser ();
xmlTempDoc = parser.parseFromString (p_strText,"text/xml");
} else {
xmlTempDoc = new ActiveXObject ("Microsoft.XMLDOM");
xmlTempDoc.async = "false";
xmlTempDoc.loadXML (p_strText);
}
return xmlTempDoc;
}
//
function removeIgnoreInFlashFreeNodes (p_strXMLData) {
for (var i = 0; i < p_strXMLData.childNodes.length; i++) {
var strChild = p_strXMLData.childNodes[i];
if (strChild.nodeName == 'span') {
var removeThisNode = false;
if (strChild.getAttribute ("ignoreIn") == "true") {
xmlDoc.documentElement.removeChild (xmlDoc.getElementsByTagName ("span")[i]); 
removeThisNode = true;
}
if  (removeThisNode) {
i--;
continue;
}
}
if  (strChild.hasChildNodes ()) {
removeIgnoreInFlashFreeNodes (strChild);
}
}
}
xmlDoc = loadXMLString (strText);
removeIgnoreInFlashFreeNodes (xmlDoc);

But the code is not working properly.

[Dormilich]

why using childNodes, when you can access the spans via getElementsByTa gName()?

PS.

function removeNode(elem)
{
    elem.parentNode.removeChild(elem);
}

Thanks a lot Dormilich!

It works by using getElementsByTa gName.
