invalid XML characters

Posted By:      Posted Date: October 08, 2010    Points: 0   Category :.NET Framework

I have a text file(UTF-8) file. Content of this file is extracted form rich text documents, it might be MS Word, PDF, HTML or any thing. I have to pass this content to a web service, but most of time it contain invalid characters like form feed or null. What happens now is when I pass the content of the file, containing invalid character, to the web service it throw exception (not a valid XML character).

As i found few characters that are not valid for XML but can i have a proper .NET function the clean the string and remove all invalid characters or can i have a list of Invalid characters for any authentic site.


Thanks for your help in advance.

Microsoft Project 2010 synchronize with SharePoint Foundation error (invalid characters)


I have been unable to synchronize my MS Project with a SharePoint Foundation tasks list. Each time I try I get the following message:

"Unable to synchronize the project with the SharePoint tasks list because the list name contains invalid characters. Modify the list name and synchronize again. Valid list names cannot contain any of the following characters: !.[]'"

I click OK and the process stops. It creates the Task list in SharePoint but does no more.

The SharePoint task list name is not the issue. I've tried a few (Project Tasks, tasks etc). It's not the Task Name in Project either. I'm using a test project file with only two tasks called "Startup" and "planning".

Any ideas?

Problem Cleaning Illegal Characters out of an XML String



I'm trying to strip illegal characters out of an XML string before I send it off to a public web service.  The xml will look something like this:

<field name="first_name">George</field>
<field name="last_name">Harrison</field>
<field name="notes">This is a note.  Any character could appear here</field>

I need to pull out any ampercand (&) charachters in the any of the fields, as well as any < or > characters, which would make the XML unreadable.

I've tried it like this:

Private Shared Function cleanQuery(ByVal queryNode As String) As String 
    Dim root As XElement = XElement.Parse(queryNode) 
    For Each x As XElement In root.Elements 
        x.Value = x.Value.Replace("&", "&").Replace("<", "<").Replace(">", ">") 
    Return root.ToString() 
End Function


That doesn't work so well.  I get the error stating:

     There are multiple root elements. Line 1, position 15.

I tried wrapping the XML in a single root element, like this:

Private Shared Function cleanQuery2(ByVal q

IE 8 Issues with Chinese/Japanese Characters


On my web application, I display information in different languages. Everything works fine in IE compatibility mode and FireFox but it shows boxes for chinese/japanese languages. I am pretty much having the same issue as described here



Thanks for your help.

Store and display Japanese characters



Can anyone tell me the best way of storing Japanese characters through ASP.NET.
I have to put characters into a asp:textbox on one page, which saves it to an Access DB.
On a second page I want to display the content in a asp:label.

Should I store the characters directly to the database or should they be encoded, and
how do I encode the characters? 

In my web.config i have:

<globalization fileEncoding="ISO-2022-JP" requestEncoding="ISO-2022-JP" responseEncoding="ISO-2022-JP" culture="ja-JP" uiCulture="ja-JP" />  

On the display page I have:

<meta HTTP-EQUIV="Content-Type" CONTENT="text/html;CHARSET=shift_jis">

string.Split - not all characters allowed as separator



I am working on a site where I use the Split function on a string.

To make sure I used a separator character that I do not use anywhere in the data I selected the character '£'.

This worked fine in Firefox and Safari, but in IE8 I get an 'Index out of range' error, so apparently the '£' character is not handled correctly.

I changed the separator to ';', and then it works fine.

Problems Rendering Special Characters


Good afternoon ASP programmers,

I am creating an application that creates math problems for students.  I wish to use a special character for negation to differentiate it from the minus sign.  I am using the Unicode character U02c9. 


This is a composite screen shot of two problems. The top one is rendered in Fire Fox and the bottom one in IE.  I'd like to know how to change my JavaScript so that IE is rendered like Fire Fox.  I have created variables that I use for my special characters.

var symMul= "×";
var symDiv= "÷";
var symNeg= "?";

Both IE & Fire Fox correctly render the symDiv and symMul symbols. Any suggestion would be greatly appreciated.




Using Editor to support Spanish characters?


I recently switched from freetextbox to the built in Ajax editor because of issues ftb had with update panels.  The Ajax editor works great except for one problem, it messes up my spanish characters.  For instance, it will replace ñ with ? and post the ? to my database.  Is there anyway to not make it do this and leave it as the actual ñ ?  if the same characters is placed in a standard textbox it will submit with no problem.

Thanks for your time!

Linq2Sql error: "Invalid attempt to call Read when reader is closed."


I've read up on this error from other posts and on other sites, but haven't found a solid resolution to the issue yet. My setup is as follows:

I have a RepositoryBase class that fields certain db calls that all repositories need to perform. In one such call, "GetSecurityGroup", it works most of the time, but will seemingly at random throw an exception with the error "Invalid attempt to call Read when reader is closed." All other Repository classes inherit from this one, and they all use the same DataContext object, which I understand isn't thread safe. Since there could be multiple calls to the DataContext object on the same page, perhaps one is using the DataContext when the next tries to do so. I'm not sure. What can I do to ensure this doesn't happen?

DropDownList FindByText with Special Characters...?


I have a dropdownlist which I dynamically select a list item using findbytext as long as there are no special characters.  One entry in the list starts with a percent symbol which I have been unable to dyncamically select.  I have confirmed that there are no spaces in the list item and have hard coded the query with the string to try to find the problem.  FindByText("% Increase")    I believe it has something to do with the special character but have been unable to identify a method to work around this.  Any help would be appreciated.

Invalid URL"" after copy or move a document.



We have an website that have 3 libraries. The "first Library" is used only to edit documents and it's called "my documents". When a user finish of edit your documents here, they start a workflow that will check fields in the document and move the document for the second library (using Sharepoint Designer Workflow - without custom actions).
In "second library" we have a big workflow. This WF has some steps for approve, collect feedback, generate sub-tasks and others things related for the document. This WF use many custom actions in (Sharepoint Designer).
When this WF arrives to the end, the document is moved to "third library", that is a official repository of documents in the enterprise.
The entire cycle works fine. But when someone creates a internal copy of the document in the "first library" to begin again the flow, we receive a Invalid Url error. It occurs when any update operations is executed over the document item, the value is conserved but the error is displayed. After it, we can not execute other workflows over the item.
If we save the document in local disk, delete the library item, and then upload it again, the problem is solved.

Some one have an idea about why and how solve it?  We are using WSS 3.0.

The following is an error registred in log file when you d

User group invalid for new document



Defined a user group and a site column of type people/group directing to this group.

Also defined a content type and added the site column to this content type.

When I create a new word document of this content type, word opens displaying my site column ok. But when I enter it, I see that all active directory (AD) entries are displayed. I want it to display only those users I added to the user group I created. Moreover, users can select any user from AD, which makes defining a user group and a site column meaningless.

This problem is only in creating new documents with Word. If I edit properties of an already existing document in my site, everything is ok: I can select only the users in the group.
