    Xmlhttp.send(); break when html document processes xml document


    I am using the exact example from W3C at http://www.w3schools.com/xml/xml_to_html.asp and it seems to fail at the 'xmlhttp.send()' line. My html document is:

    Code:
    <!DOCTYPE html> <html> <body> <script> if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.open("GET","cd_catalog.xml",false); xmlhttp.send(); xmlDoc=xmlhttp.responseXML; document.write("<table border='1'>"); var x=xmlDoc.getElementsByTagName("CD"); for (i=0;i<x.length;i++) { document.write("<tr><td>"); document.write(x[i].getElementsByTagName("ARTIST")[0].childNodes[0].nodeValue); document.write("</td><td>"); document.write(x[i].getElementsByTagName("TITLE")[0].childNodes[0].nodeValue); document.write("</td></tr>"); } document.write("</table>"); </script> </body> </html>
    My xml document is:
    Code:
    <?xml version="1.0" encoding="ISO-8859-1"?> <!-- Edited by XMLSpy® --> <CATALOG> <CD> <TITLE>Empire Burlesque</TITLE> <ARTIST>Bob Dylan</ARTIST> <COUNTRY>USA</COUNTRY> <COMPANY>Columbia</COMPANY> <PRICE>10.90</PRICE> <YEAR>1985</YEAR> </CD> <CD> <TITLE>Hide your heart</TITLE> <ARTIST>Bonnie Tyler</ARTIST> <COUNTRY>UK</COUNTRY> <COMPANY>CBS Records</COMPANY> <PRICE>9.90</PRICE> <YEAR>1988</YEAR> </CD> <CD> <TITLE>Greatest Hits</TITLE> <ARTIST>Dolly Parton</ARTIST> <COUNTRY>USA</COUNTRY> <COMPANY>RCA</COMPANY> <PRICE>9.90</PRICE> <YEAR>1982</YEAR> </CD> <CD> <TITLE>Still got the blues</TITLE> <ARTIST>Gary Moore</ARTIST> <COUNTRY>UK</COUNTRY> <COMPANY>Virgin records</COMPANY> <PRICE>10.20</PRICE> <YEAR>1990</YEAR> </CD> <CD> <TITLE>Eros</TITLE> <ARTIST>Eros Ramazzotti</ARTIST> <COUNTRY>EU</COUNTRY> <COMPANY>BMG</COMPANY> <PRICE>9.90</PRICE> <YEAR>1997</YEAR> </CD> <CD> <TITLE>One night only</TITLE> <ARTIST>Bee Gees</ARTIST> <COUNTRY>UK</COUNTRY> <COMPANY>Polydor</COMPANY> <PRICE>10.90</PRICE> <YEAR>1998</YEAR> </CD> <CD> <TITLE>Sylvias Mother</TITLE> <ARTIST>Dr.Hook</ARTIST> <COUNTRY>UK</COUNTRY> <COMPANY>CBS</COMPANY> <PRICE>8.10</PRICE> <YEAR>1973</YEAR> </CD> <CD> <TITLE>Maggie May</TITLE> <ARTIST>Rod Stewart</ARTIST> <COUNTRY>UK</COUNTRY> <COMPANY>Pickwick</COMPANY> <PRICE>8.50</PRICE> <YEAR>1990</YEAR> </CD> <CD> <TITLE>Romanza</TITLE> <ARTIST>Andrea Bocelli</ARTIST> <COUNTRY>EU</COUNTRY> <COMPANY>Polydor</COMPANY> <PRICE>10.80</PRICE> <YEAR>1996</YEAR> </CD> <CD> <TITLE>When a man loves a woman</TITLE> <ARTIST>Percy Sledge</ARTIST> <COUNTRY>USA</COUNTRY> <COMPANY>Atlantic</COMPANY> <PRICE>8.70</PRICE> <YEAR>1987</YEAR> </CD> <CD> <TITLE>Black angel</TITLE> <ARTIST>Savage Rose</ARTIST> <COUNTRY>EU</COUNTRY> <COMPANY>Mega</COMPANY> <PRICE>10.90</PRICE> <YEAR>1995</YEAR> </CD> <CD> <TITLE>1999 Grammy Nominees</TITLE> <ARTIST>Many</ARTIST> <COUNTRY>USA</COUNTRY> <COMPANY>Grammy</COMPANY> <PRICE>10.20</PRICE> <YEAR>1999</YEAR> </CD> <CD> <TITLE>For the good times</TITLE> <ARTIST>Kenny Rogers</ARTIST> <COUNTRY>UK</COUNTRY> <COMPANY>Mucik Master</COMPANY> <PRICE>8.70</PRICE> <YEAR>1995</YEAR> </CD> <CD> <TITLE>Big Willie style</TITLE> <ARTIST>Will Smith</ARTIST> <COUNTRY>USA</COUNTRY> <COMPANY>Columbia</COMPANY> <PRICE>9.90</PRICE> <YEAR>1997</YEAR> </CD> <CD> <TITLE>Tupelo Honey</TITLE> <ARTIST>Van Morrison</ARTIST> <COUNTRY>UK</COUNTRY> <COMPANY>Polydor</COMPANY> <PRICE>8.20</PRICE> <YEAR>1971</YEAR> </CD> <CD> <TITLE>Soulsville</TITLE> <ARTIST>Jorn Hoel</ARTIST> <COUNTRY>Norway</COUNTRY> <COMPANY>WEA</COMPANY> <PRICE>7.90</PRICE> <YEAR>1996</YEAR> </CD> <CD> <TITLE>The very best of</TITLE> <ARTIST>Cat Stevens</ARTIST> <COUNTRY>UK</COUNTRY> <COMPANY>Island</COMPANY> <PRICE>8.90</PRICE> <YEAR>1990</YEAR> </CD> <CD> <TITLE>Stop</TITLE> <ARTIST>Sam Brown</ARTIST> <COUNTRY>UK</COUNTRY> <COMPANY>A and M</COMPANY> <PRICE>8.90</PRICE> <YEAR>1988</YEAR> </CD> <CD> <TITLE>Bridge of Spies</TITLE> <ARTIST>T'Pau</ARTIST> <COUNTRY>UK</COUNTRY> <COMPANY>Siren</COMPANY> <PRICE>7.90</PRICE> <YEAR>1987</YEAR> </CD> <CD> <TITLE>Private Dancer</TITLE> <ARTIST>Tina Turner</ARTIST> <COUNTRY>UK</COUNTRY> <COMPANY>Capitol</COMPANY> <PRICE>8.90</PRICE> <YEAR>1983</YEAR> </CD> <CD> <TITLE>Midt om natten</TITLE> <ARTIST>Kim Larsen</ARTIST> <COUNTRY>EU</COUNTRY> <COMPANY>Medley</COMPANY> <PRICE>7.80</PRICE> <YEAR>1983</YEAR> </CD> <CD> <TITLE>Pavarotti Gala Concert</TITLE> <ARTIST>Luciano Pavarotti</ARTIST> <COUNTRY>UK</COUNTRY> <COMPANY>DECCA</COMPANY> <PRICE>9.90</PRICE> <YEAR>1991</YEAR> </CD> <CD> <TITLE>The dock of the bay</TITLE> <ARTIST>Otis Redding</ARTIST> <COUNTRY>USA</COUNTRY> <COMPANY>Atlantic</COMPANY> <PRICE>7.90</PRICE> <YEAR>1987</YEAR> </CD> <CD> <TITLE>Picture book</TITLE> <ARTIST>Simply Red</ARTIST> <COUNTRY>EU</COUNTRY> <COMPANY>Elektra</COMPANY> <PRICE>7.20</PRICE> <YEAR>1985</YEAR> </CD> <CD> <TITLE>Red</TITLE> <ARTIST>The Communards</ARTIST> <COUNTRY>UK</COUNTRY> <COMPANY>London</COMPANY> <PRICE>7.80</PRICE> <YEAR>1987</YEAR> </CD> <CD> <TITLE>Unchain my heart</TITLE> <ARTIST>Joe Cocker</ARTIST> <COUNTRY>USA</COUNTRY> <COMPANY>EMI</COMPANY> <PRICE>8.20</PRICE> <YEAR>1987</YEAR> </CD> </CATALOG>
    The page does not render as expected in both IE and Chrome (blank page).

    I remember reading about that some where, there is an issue with access the XML nodes, in some browsers; when trying to acquire them with this method, but I cannot remember what the exact issue was. Open up your developer's console and see if your getting an/any error(s) and if so..., what is the error(s).

    It shouldn't be... when tried at home (locally),
    unless your home is also a web server ?

    SOLVED (I think)


    I believe the problem is that the xmlhttp.send(); line wants a server response and IE/Chrome know this and prevent the page from rendering locally but renders find on a web server. Firefox renders locally just fine.

    Thanks for the responses!

    • web_loone08 agrees : Yeah, it probably is a browser security measure, that prevents you from doing it locally.
