I am trying to read an XML file for my website. I am hitting a wall when trying to read a local (same folder as the web page) XML file and put its content on to my web page.

I have tried numerous tutorials from interweb to the same result. Firefox refuses to read the html tags for some reason. Being a total noob on this side, I would really appreciate some help on this

Here is the HTML code,

<HTML>
<HEAD>
<TITLE>Read Firefox</TITLE>
<script>
var xmlDoc=document.implementation.createDocument("","",null);
xmlDoc.load("someXMLfile.xmlddocument.write(xmlDoc.getElementsByTagName("employeedocument.write("<br;length = "+ xmlDoc.getElementsByTagName("employee").length);
document.write("<br;first child = "+ xmlDoc.getElementsByTagName("employee").firstChild);

&lt;/script&gt;
&lt;/HEAD&gt;

&lt;BODY&gt;

&lt;/BODY&gt;
&lt;/HTML&gt;

The XML file used,

&lt;?xml version="1.0" ?&gt;  
&lt;root&gt;
 &lt;node&gt;Node1&lt;/node&gt;
 &lt;node&gt;Node2&lt;/node&gt;
&lt;/root&gt;

I have attached both files to this post as well.

thanks in advance

Starting from the beginning:

1. You're running the script inline, which means the browser might not have the document object yet. Run the code on window.onload (or equivalent).

2. There are no <employee> nodes, so it won't find any.

3. document.getElementsByTagName() returns a collection of objects, so the most you could hope for is something like '[xmlObject collection]' when using document.write against it.

4. As there are no <employee> nodes, any call to a property of the collection will fail (it is undefined), so .length and .firstChild won't work.

5. .firstChild returns an object which when written to the document (implies .toString()) normally outputs any text nodes within it (bits within tag pairs). Is this the required behaviour or do you actually want the first child?

    • Windows 10 is the reason why we are so conscious about privacy now

      By Big John Studd · Posted

      A rotten article full of handwaving of anti-consumer practices. Aside from the fact that no, not even close to every piece of major software collects information about its users, ethical developers make such telemetry opt-in and allow it to be completely disabled. To use KDE Plasma as an example, you're shown a greeter upon first boot that gives users the option to send the developers telemetry, with the default being off and 'off' actually meaning off. Windows 10 has never offered that capability - only a promise that Microsoft will slurp up less of your data if you spend time tweaking 50 different privacy settings. There is still absolutely no way to completely opt out of sending Microsoft telemetry in any version of Windows 10 (or 11, naturally). Even using group policy in Enterprise editions only allows you to reduce telemetry to the bare minimum. Home-focused editions don't even get that option. Articles like this dismissing user privacy concerns as "FUD" are a part of the reason Microsoft felt confident enough to go so much further with Windows 11. I guess you get what you deserve in that respect. Personally, I finally made the move to Linux after 15 years or so of dabbling with it, but never really considering a permanent switch. Enjoy your bright, shiny Windows future. You asked for it, after all.
    • Microsoft shares Defender update for new Windows 11/10 ISO installs

      Microsoft shares Defender update for new Windows 11/10 ISO installs by Sayan Sen Aside from new Windows setup and recovery updates, Microsoft has also published a new Defender update for Windows 11/10/Server installation images this week. This update package is necessary as a Windows installation image may contain old, outdated anti-malware definitions and software binaries. Aside from better security, these updates can also provide improved performance benefits in some cases. When a new Windows installation is set up, there may be a temporary security risk due to outdated Microsoft Defender protection in the OS installation images. This happens because the antimalware software included in these images might not be up to date. Thus Microsoft says that these updated definitions essentially help close this protection gap. Microsoft delivered the latest security definitions for Windows images via security intelligence update version 1.431.54.0. The Defender package version is also the same. It applies to Windows 11, Windows 10 (Enterprise, Pro, and Home editions), Windows Server 2022, Windows Server 2019, and Windows Server 2016. Microsoft writes: From Microsoft's security bulletin, we learn that the security intelligence update version 1.431.452.0 was released this past week adds threat detections for various backdoor and phishing exploits, trojans, and more. For those wondering, the latest intelligence update is version 1.431.155.0 at the time of writing.

      Probably.   You'll probably want to see what channels you'd pick up by entering your zip code here... https://www.channelmaster.com/pages/free-tv-channels   With respect to the antenna and box you selected... no idea.  They are both non-brand names and cheap.  So...sure.  I have no idea how that box records...but it's listed as a feature. Also...I have no recommendations.  I haven't recorded from a cable box (ClearQAM) in over 10 years (maybe 20?).  This was Windows Media Center/MythTV days.  My Hauppauge is just collecting dust somewhere in my expansion slot bin.

      Yea, I tried to do that with my janky WINDOWS MEDIA CENTER Frankenstein, and it failed miserably.
