How to open an XML file in a richtextbox and.....++

Chantal Decraie

Hi,

could someone explain to me how I could open an XML file in a richtextbox without using the openFileDialog please?

It's as this:

I first tried to use the openFileDialog to open my file and give it back in a richtextbox. So far, no problem. I could see the Xml file as is. But when I wanted to change some fields in it using XmlReader, XmlDocument, etc.. the file is read with backwards slashes and spaces in it. where of course the readers gives error message about strange characters that they can't read.

"\n\n \n 45071dc8-558d-439a-8f0a-88ae73a74910\n 386\n 2016-06-14T12:31:58.0+01:00\n \n 5414488009809\n \n \n 0000000000000 \n \n \n 5414488009809\n

So I'm guessing I need to leave the openFileDialog and try to load the xml file.... or maybe the whole folder with xml files to show up in a tree or something like that . Because the purpose is to change some nodes in the files hardcoded afterwards.

I have added the code that I already have in a notepad.

Thanks in advance.

I have found the solution on my issue.
the first mistake I made was using an XmlTextReader AND an XmlDocument for the same text that will collide against each other. No need to use both to read the Xml file.
Secondly, when creating a new XmlDocument don't instantiate your object into a string to call it in the XmlDocument. Just use the text of the object instead like this.

XmlDocument doc = new XmlDocument();
doc.LoadXml(richTextBox1.Text); //<==
XmlNodeList nodeList = doc.DocumentElement.SelectNodes("/AnXMLTestFile/");

hello Nilesh, Thanks for answering.
For security reasons I can't upload the whole file but the way the XML is created is the same for the whole file:





I say this because in my code I have other nodes that are not in the file that I'm adding but they do exist. ;-)
Thanks for your time.

can you please post your whole project code as a rar file along with the xml file you are working with?
