JAVASCRIPT selectNodes() returns 0 if XML contains '&' char

2-Feb-09 2:44

Hi,

so first of all change the script-tag for javascript to this:

<script type="text/javascript">

This will ensure that the function is found.

And ensure that setting the url ends with a semicolon in your javascript.

Btw. Firefox offers a great tool called "error console" (filed under extras), great for checking errors with javascript.

Let me know if this helped you.

Hi ,

I want to parse XML values in javascript. The problem is if XML values does not have either of '&' char, thing working nicely.

<DataSet>
	<Row>
		<NDOCUMENTID>499</NDOCUMENTID>
		<TDESCRIPTION>my god</TDESCRIPTION>
		<TDISPLAYNAME>my god</TDISPLAYNAME>
		<TTITLE>my god</TTITLE>
		<NPARENT_DOC_ID>0</NPARENT_DOC_ID>
		<NPARENT_FOLDER_ID>496</NPARENT_FOLDER_ID>
	</Row>
	<Row>
		<NDOCUMENTID>501</NDOCUMENTID>
		<TDESCRIPTION>Level 2Folder</TDESCRIPTION>
		<TDISPLAYNAME>Level 2Folder</TDISPLAYNAME>
		<TTITLE>Level 2Folder</TTITLE>
		<NPARENT_DOC_ID>0</NPARENT_DOC_ID>
		<NPARENT_FOLDER_ID>500</NPARENT_FOLDER_ID>
	</Row>
</DataSet>

but if '&' is present then 'selectNodes' function does not select any row.

<DataSet>
	<Row>
		<NDOCUMENTID>499</NDOCUMENTID>
		<TDESCRIPTION>my &amp; god</TDESCRIPTION>
		<TDISPLAYNAME>my god</TDISPLAYNAME>
		<TTITLE>my god</TTITLE>
		<NPARENT_DOC_ID>0</NPARENT_DOC_ID>
		<NPARENT_FOLDER_ID>496</NPARENT_FOLDER_ID>
	</Row>
	<Row>
		<NDOCUMENTID>501</NDOCUMENTID>
		<TDESCRIPTION>Level 2Folder</TDESCRIPTION>
		<TDISPLAYNAME>Level 2Folder</TDISPLAYNAME>
		<TTITLE>Level 2Folder</TTITLE>
		<NPARENT_DOC_ID>0</NPARENT_DOC_ID>
		<NPARENT_FOLDER_ID>500</NPARENT_FOLDER_ID>
	</Row>
</DataSet>

Any help is appreciated. Thanks in advance.
follong is my javascript code which I am using for parsing XML.

<script language="javascript" type="text/javascript">
            var callerWindow = this.opener;
            
            var sXML = document.getElementById("idAllFolders").value;
            alert(sXML);
            var objSelection;
            var sFolderName, sFolderID;
            var objFolderNodes;
            var nSelectedValue = 0;
            var objXML = new ActiveXObject("MSXML2.DomDocument");
            
            objSelection = document.getElementById("selFolders1") 
            objXML.loadXML(sXML);
          
            try
            {           
                objFolderNodes = objXML.selectNodes("//DataSet/Row[NPARENT_FOLDER_ID = '496']"); 
                alert("objFolderNodes.length :"+objFolderNodes.length);//THIS LINE RETURNS 0 
                                                                       //IF '&' PRESENT IN xml
            }
            catch(e)
            {
            }    
    </script>

Hi,

could be. I think since ASP.NET is released by Microsoft they focused on IE. As far as I know there are some things that work not so good with Firefox. But please be more specific with "doesn't give the expected result". What do you want to achieve?

so entries in our app.config cannot be used in app.xml in WPF apps? can we just cut and paste entries from app.config into app.xaml? What about third party support from say log4met/nhibernate and spring.net?

Sorry new to WPF

Thanks

still trying to catch up on WPF and silverlight, just wondering if I can write on set of XAML for WPF windows client sever app, and use that same XAML to port that application to a web application? Is that the idea behind XAML? That you only need to define user interface ONCE using xaml, and you can render it to both windows client app + (WPF Browser app) web app version?

Thanks!

CSS Problems in IE [modified]

My current website uses PHP. I'm re-creating it using ASP.Net (2.0). I've got the page displaying correctly under FireFox, but IE6 is hosing up the layout. Here's a link to the site:

Paddedwall.org (for .Net)[^]

Under IE6, the following visual elements are "wrong":

0) The header text that shows up on the right side under FireFox isn't displayed at all under IE6.

~~1) The size of the <h1> text is significantly larger under IE6 (FireFox is showing the desired size).~~

2) The content panel (the one with the white background) is fine in FireFox, but in IE6, it extends all the way to the bottom of the browser window, and the footer panel is being shown on top of it.

Can someone help me figure out what the hell I've done here?

BTW, I haven't tried this under Opera yet, but I'm off to download it right now.

[EDIT] It looks fine in Opera.

[EDIT] I figured out the font size problem in the <h1> tags.

I checked you page and found all the content placed on the page is in div tags.

Behaviour of div tags differ in browsers

Suggest you to use table tag for placing page content.

Quote Selected Text

The behaviour of div tags between browsers is much more consistent than the behaviour of tables...

Don't use tables for layout[^]

Despite everything, the person most likely to be fooling you next is yourself.

The header problem:
You've fixed the width of the page at 950px, and sized the floating boxes contained therein at 400px and 550px. However, the quote box contained in the left floating box is sized at 100% + 3px of left padding - putting the width at 403px. IE then overrides the set width of the outer box, making it 403px as well. Since both boxes float, this forces the right box to wrap; since the header is styled with overflow:hidden, the wrapped box disappears.

Potential header solutions:

Change the width style in the HeaderQuoteBox rule to auto (instead of 100%) - will then become only as wide as its parent allows (400px).
Remove the float and width styles from the rule for HeaderRight. This will put the right box back into the normal flow, letting the left box float to its left.
Add overflow: hidden; style to the rule for HeaderLeft. This will cut 3px off of the 403px width of the inner box, allowing both floating boxes to appear on the same line (but potentially cutting off content in the HeaderLeft box).

The scrolling content panel problem:
You're positioning the PageContent div using absolute top and bottom coordinates. This works great in every browser that isn't IE6... But IE6 decides the two positions conflict, and ignores one. This particular bit of IE madness is well-documented, and a good workaround (using IE's expression feature) can be found on A List Apart[^].

The scrolling content panel solution:
Add the following code to your page to patch up IE6:

    <!--[if lt IE 7]>
    <style type="text/css">
    #PageContent
    {
        /* body height - header - footer - padding - border */
        height:expression(document.body.clientHeight-144-24-10-2);
    }
    </style>
    <![endif]-->

Hi,

I am getting base64 text and i want to generate a png image from it. Can anyone please suggest me a good encoder or decode for the same. If anyone knows how to go about with yhis then plz help. The coding for the application is done using VB(using COM) and ASP. So any encoder or decoder making use of VB will be more useful. Plz provide me the details of the links if any.

Regards,

Hi,

does the base64-text contains the bytes of a png? If yes, then just convert the string with the Convert.FromBase64String into a byte-array, put these into a memorystream and load the image using the Image.FromStream() where you pass the memorystream.

Does this help you?

Could you be so kind to describe exactly what you want to do? As I see it, the posted answers should enable you to write your own tool (not more than 10 loc).
