# Writing online XML file to textbox

I am using a PHP [script](https://www.mindstick.com/interview/477/how-can-i-execute-a-php-script-using-command-line) to generate xml files. I want to write the [data](https://www.mindstick.com/articles/13050/salesforce-aiming-to-dominate-predictive-analytics-with-data-science) in the [XML file](https://www.mindstick.com/forum/360/how-to-read-xml-file-in-php) to a Textblock in my [Windows](https://www.mindstick.com/articles/311752/how-to-install-and-use-the-google-wifi-software-on-a-windows-or-mac-computer) [Phone](https://www.mindstick.com/articles/23411/the-most-effective-method-to-find-the-perfect-small-business-phone-system-for-your-business) 8 App. When I [debug](https://www.mindstick.com/forum/156/how-to-debug-application-on-the-server), I get an [error](https://yourviews.mindstick.com/view/88527/fixing-quickbooks-error-4120-reinstalling-vs-repairing) which is not caught my the [catch](https://www.mindstick.com/forum/159341/how-to-use-try-and-catch-in-java-for-exception-handling-and-what-happens-when-an-exception-occurs)

**This is my [code](https://yourviews.mindstick.com/view/85458/alan-turing-the-mastermind-behind-cracking-the-enigma-code-during-world-war-ii):**

Hi Chintoo,

I believe you must access tb1 from the UI thread, so I would suggest trying to use a statement similar to this:

```
case XmlNodeType.Text: //De tekst in elk element weergeven.{    tb1.Dispatcher.BeginInvoke(() =>    {        tb1.Text = tb1.Text + reader.Value + "\r\n";    });    Console.WriteLine(reader.Value);}break;
```
