Question: I have a WebBrowser control in my Windows form application to display XML files. I am using web browser control so that I get the auto-formatting that web browser provides for my XML file, along with all other benefits of a web browser.

Now the problem is, the WebBrowser by default displays the background color in white when I open the XML file. I like to change it to another color, light blue. How to do this?

I tried some approaches like:

```
webBrowser.Document.Body.SetAttribute("bgcolor", "#738A9C");

webBrowser.DocumentText = "<html><body style='background-color:Blue'></body></html>";

```

But din't help. Any way to achieve this through CSS or XSLT or something?

Answer: 
With grep:

```
grep -o '\b65\b[^,]*' <<<"$var"
65:3.0

```

Or 

```
grep -oP '\b65\b:\K[^,]*' <<<"$var"
3.0

```

`\K` option ignores everything before matched pattern and ignore pattern itself. It's Perl-compatibility(`-P`) for `grep` command .
Try egrep like below:

```
echo $myvar | egrep -o '\b65:[0-9]+.[0-9]+' | 

```
