XElement.Parse Unexpected End Of File. Elements Are Not Closed
Jun 10, 2011
I am trying to parse incoming data from a serial port that appears to be XML format but an exception is thrown when I switch from a simulated setup to the real deal.My program runs great in a simulated setup but when I try it out on the real device I get: XmlException was unhandled Unexpected end of file has occurred. The following elements are not closed: li840 line 1, position 9.The li840 tag is my root tag and the position never seems to get past 40. I've tried using a try catch block but in my in both my simulated and real setups my values are blank but the program will run without exceptions. Should I take my received data and put it into a file and then read from the file? or is there something else I can do to make this work properly? [code]

Pretty much the only thing I have changed is created a loop because I have one xmlstring and want to break it up and create tif files from it(which it actually does do).My problem is this: readbytes inside the while loop throws an exception at the last time through the loop that says I have an "unexpected end of file; the following elements are not closed" and lists them
[code]...
So there are tags left open after the readtofollowing("image"). I tried catching the exception to no avail, tried to read until eof, no avail. I dont really need elements to be closed, I just need to continue because I created files using whats in the image tag.EDIT: I think my xmlstring is going to have times where it will be too big to do a parse without slowing down too much.../parsing binary data?

I am reading a large number of XML files and do not want my program to bomb on exceptions. I am making great strides in reporting the errors, skipping the offending files and continuing the import process. However I am having problems with XmlExceptions. I get the following XmlException on the While textReader.Read() line of my program:
Quote:
XmlException was unhandled
Unexpected end of file has occurred. The following elements are not closed:
my:PicInsert, my:PictureGroup, my:myFields. Line 153, position 430817.
I am finding some of the reasons why, missing tags etc, but those aren't really my concern. I just want to report the issue and continue. I am thinking about some kind of check for a valid xml file but fear that that might not catch it all. For example I had a image tag in one of the files that was missing an alt="" attribute and I am not sure if that would invalidate the entire XML file.What would be the best way to trap and deal with the exception with out causing interuption to the program?

If I have a text stored in db, file, resource does not matter:
<code><%= Integer.MaxValue %></code>
Is there a way to do this: Dim el As XElement = XElement.Parse({variable containing text above}) and to have it evaluate the expression Integer.MaxValue?

I'm creating a program (Which will eventually be a service) which loops a section of code which downloads files from a variety of FTP servers.All files are succesfully downloaded on the first iteration, however after this the download fails with the following error..."The underlying connection was closed: An unexpected error occurred on a receive."Curiously, the error does not occur if the loop only downloads the same file from the same Ftp server. It only occurs when 2 or more files are downloaded.I use the following code...
Dim fwr As FtpWebRequest = CType(FtpWebRequest.Create(Supplier.FTP_Address & Supplier.FilePath & Supplier.FromFile), FtpWebRequest)
'Set credentials
fwr.Credentials = New NetworkCredential(Supplier.Username, Supplier.Password)

I need to read an xml document from a database record into an XDocument object in order for it to be deserialized. So that the deserialization will work, I need to apply a specific namespace to each of the level 1 elements. So XML looks a bit like this:
[Code]...
How do I prevent the blank/empty namespace being added to each child element of the element to which the required namespace has been applied?

tell me an efficient method of retrieving the CSS between tags on a page of markup in .NET?I've come up with a method which uses recursion, Split() and CompareTo() but is really long-winded, and I feel sure that there must be a far shorter (and more clever) method of doing the same.it is possible to have more than one element on a page, and that the element can be either or .

I'm working with a class that inherits the XElement class.The new class is called MXElement.It adds some new functionality to it for navigating through the XML tree, as well as some more information regarding attributes, but that's not particularly important.My problem is that I have an XML Tree filled with XElement objects.However, when I create a new MXElement object from the XElement object before, it is just a copy of that object. This means that any changes that I make to this object will not effect the original tree.I suppose what I'm asking for is a way to build in the functionality for my MXElement class and keep references to the original XElement objects.If possible, I would really prefer to keep MXElement a child class instead of building a lot of extension methods for XElement.

I am using XElement to manipulate my xml file: to find target node and then add child node to it. But now I have one problem. Let's say my xml file looks like this:
<Report xmlns="MY_NAMESPACE"
<Width>100</Width>
<Height>100</Height>
[Code].....
The second <ReportItem> is the newly-added one, but sadly this is not a valid file (my parser is complaining in the further processing of xml file). So how can I make this new item look exactly like the existing one, without any namespace? This has been driving me crazy. I spent a whole day to figure out that I need to add the curly brackets so that it will find the target node (it doesn't work like what the link above says that it adds and searches the default NS automatically), but now it adds something unnecessary?

I would like to add a XElement into an existing XElement as a child
Dim myDocument As New XDocument
myDocument.Declaration = New XDeclaration("1.0", "utf-8", "no")
myDocument.Add(New XComment("XComment"))
[Code]....
What is the best way? There will be at least one rule but there could be as many as 4 total.

I'm trying figure out if this is possible. Basically, I need to create an XElement and then add one or more siblings to that XElement, but without a parent. I'll add that list of XElements to a Parent later, but need some flexibility in building this and other lists of XElements before doing so. Is this possible?
So I would have something like:
Public items As XElement = <ItemA>Something</ItemA>
And then I need to add an element so that the result looks like:
<ItemA>Something</ItemA>
<ItemB>Something Else</ItemB>
That result is what I need to pass around as a single object. I've messed arounnd with IEnumerable(Of XElement), but there is no .Add.

I'm building XML based on some data pulled from a database, and thought to try building the XML with LINQ2XML. The data is coming from a few different places, so I've been building the XML by sections, based on what I have populated in DataTable objects. Using the XElements and XAttributes, I can get one or the other, but I was wondering if anyone had insight in how to make the determination of whether to use XElement or XAttribute at the point where the XML is being built.[code]So it's in that LINQ query that I need to determine if ValueToParse, for example, has a valid value (non-empty). If it does, then I can add the node and it's value. If it DOES NOT, I need to add that named node, but with an attribute of 'xsi:nil="true"',The caveats are that that there are some descendants which repeat over different parents (for example, there's an AddressDetails section which contains AddressDetail elements. These AddressDetail elements can contain 0 or 1 Contacts groups of Contact elements, so adding a node to the Contacts node isn't a straightforward option as it would be if there was only ONE Contacts element).I don't usually USE LINQ, but it SEEMED like a good idea at the time XD

I have tried a few things like converting HTML to XML and then using an XML navigator to get input elements but I get lost whenever I start this process.What I am trying to do is to navigate to a website which will be loaded using textbox1.text.Then download the html and parse out the input elements like . username, password, etc and place the element by type (id or name) into the richtextbox with the attribute beside the name.[code]Any clues or how to properly execute an HTML to XML conveter, reader, parser?

I did so by chosing "add existing file". For purposes to reproducing this let's say the file is in c:emp. So I added c: emphelp.chm.
I set the properties to "copy always" under the option "copy to output directory".
Then I compiled and it worked fine.
I then updated the file in c: emp with changes and compiled. I expected the updates would be copied into my program but they did not..

I'm attempting to load an xml document from an XML column in MSSQL 2008, into an XmlDocument (see code below).
Sometimes the code will break at the xdoc.Load(xr) line with the error "Unexpected end of file and occurred". After breaking, the XmlReader has a value of "None".
While researching the problem, I saw posts that referred to a 4Kb limit on StreamReaders and figured this may be related somehow. So I cut down the size of my document (to around 4Kb) and everything worked fine.
On average, the XML documents I'm importing from the database are 20Kb.
how to get a 'large' amounts of XML from the database into my XmlDocument?
Dim xr As XmlReader = ExportAdapter.GetEditedCheckXML(chkId)
Dim xdoc As New XmlDocument
xdoc.Load(xr)

I've two Strings which I'm loading from a SQL Server 2008 database (nvarchar-field)After loading them from the database Visual Studio 2010 displays them as follows in the watch window:
str1 = "Test"
str2 = "Test"
But the comparison with str1 = str2 returns False If I write those strings to a file with UTF8 Encoding the result is as expected:
Test
Test
If I write those strings to a file with ANSI (Default) Encoding the result is NOT as expected:
?Test
Test
Converting the strings to bytes:
System.Text.Encoding.Default.GetBytes(str1) 'Returns ByteArray {63, 84, 101, 115, 116}
System.Text.Encoding.Default.GetBytes(str2) 'Returns ByteArray {84, 101, 115, 116}
System.Text.Encoding.UTF8.GetBytes(str1) 'Returns ByteArray {239, 187, 191, 84, 101, 115, 116}
System.Text.Encoding.UTF8.GetBytes(str2) 'Returns ByteArray {84, 101, 115, 116}
Where is the Byte 63 in case of ANSI Encoding OR Bytes 239, 187, 191 in case of UTF8 Encoding for str1 coming from?Well, Bytes 239, 187, 191 are the BOM for UTF8. The question here would more likely be: Why do I get the BOM for str1 but not for str2?(Well, the values are values passed to a webservice which inserts them into the database, the initial values are passed to this webservice by a client I've no control over)

for example i have this code :
Sub Month()
Dim Conn As New Data.OracleClient.OracleConnection
Conn.Open()
Try
Dim Cmd As New Data.OracleClient.OracleCommand
With Cmd
[Code]...
What will happen to the datareader when the Connection is closed ( Conn.close)
Will the Cursor that is used by the datareader be freed ? or will it stay open ?
If the cursor that is used by the datareader is still open , when will it be automatically closed ? or should i just closed it manually ?
Will it cause the dreaded "ORA-01000: maximum open cursors exceeded" ?

I created a method and pass the element type, id, and any inner text that instantiates a new html element. The last statement: Me.Controls.Add(element) adds it to the end of the page, but I would like it to be inserted in a specific position (between 2 divs within a form). What I am describing is very similar to this post on SO here, although it was for javascript.

I can't understand why I'm getting this error. I'm trying to parse a tab seperated file. After 10 lines being read it throws the above error which is an ObjectDisposedException.

I can't understand it, it's called and operates fine for the first 10 iterations and on the 11th throws and error. There is nothing special about that line in the log file.

I want to display photos of people when the mouse passes over their name. I wanted to be able to size the picture box to be proportional to the various photographs and let the Stretch property handle the rest.I used the code above offered by John Wein to a question from 2009 to read the dimension of the picture It worked fine until I pass over the same person twice. Then I get an error that the file is in use by another process.I tried adding:
"BR.Close"
With and without
"BR.Dispose"
But the file is still locked-out on the second pass. I tried setting "PictureBox.Image = Nothing" when the mouse leaves the square, still the file is seen as in use and locked.
