ajax - xml- xsl : Trying to Pull XML and then formate it correctly with xsl

airete · July 11, 2007

Hello!

so here is what i am doing or attempting to do. I have a xml doc with these "questions" and i want to pull them into my html page and display the questions. My problem is that when i pull the xml and then apply the xsl to the

responceXML, the html is not being added into the div but the values from xml are. I know my xsl works because i can open up my xml page in a browser and it is all formated nicely.It is very very weird. Since i am relatively new to JS , AJAX and xsl i figured i would come to the masters and that way you could show me the way. ^_^

here is my html/ajax/js page:

<script language="javascript" type="text/javascript">

function showFeed(xmlUrl, xslUrl) {

    var feed = document.getElementById('feed');
    //clear feed div
    while(feed.hasChildNodes()){
        feed.removeChild(feed.childNodes[0]);
    }
    //append new htmlfragment
alert(getHtmlFragment(xmlUrl, xslUrl));
    feed.innerHTML=(getHtmlFragment(xmlUrl, xslUrl));     
}

function getHtmlFragment(xmlUrl, xslUrl) {
    var xslStylesheet;
    var xsltProcessor = new XSLTProcessor();   

    //load the xml file
    var xmlSource = getResponseXml(xmlUrl).responseXML;

    //load the xsl file into the xslt Processor
    xslStylesheet = getResponseXml(xslUrl).responseXML;      
    xsltProcessor.importStylesheet(xslStylesheet);
    
    return xsltProcessor.transformToFragment(xmlSource, document).textContent; 

}

function getResponseXml(xmlUrl) {
    var xmlHttp = new XMLHttpRequest();
    xmlHttp.open("GET", xmlUrl, false);
    xmlHttp.send(null);
    return xmlHttp;   
}

ok so i have the xml coming in and the xsl formating it. But i am running into a serious where if i put in <p> or any html inside one of the xml tags for formatting it will not formate. I tried to use cdata, but it just shows the <p> and all the html tags. anyone have any ideas?

i tried to updated my above post with the new code and stuff but the modify button was not there?

to get it working i changed my showFeed function from the feed.innerHTML to appendChild.

function showFeed(xmlUrl, xslUrl) {

    var feed = document.getElementById('feed');
    //clear feed div
    while(feed.hasChildNodes()){
        feed.removeChild(feed.childNodes[0]);
    }
    //append new htmlfragment

feed.appendChild(getHtmlFragment(xmlUrl, xslUrl));
         
}

could that have something to do with it? it worked before but the form elements did not work.

I also solved the last problem too. I am just posting the solution here so that is someone else has this problem that this might help them out.

I found out the problem when saw what the DOM had rendered. When the xml was spit out on the page,the < and > had beem replaced with < and &gt instead.

in my xls i named the div that had the html in it "qData" then i created a function that put all the elements named qData in an array. Then I cycled through the array and replaced the < with < and the same for &gt.

here is the function.. and i just put it in an onload in the body,after it loaded in all the content.


function fixupContent(){

var itemList = document.getElementsByName("qData");

for (var i=0;i<itemList.length;i++) {
	var item = itemList[i];
	var text = itemList[i].innerHTML;
	text = text.replace(/</g,"<");
	text = text.replace(/>/g,">");

	itemList[i].innerHTML = text;
}


}

you can mark this as solved
