Question: My File names:
1.) about.php
2.) styles.css 

The same stylesheet is also applied to index.php .

I want to style the section part of the page. I tried it by styling the [Eg.], .section-info{color:#555;}

but it didn't helped. Also should I change the stylesheet name to styles.php? 
Thanks In Advance.

```html
<?php

/* Website Header */

    include ("include/header.php");

?>

<!-- Website Page-2 Main Content -->

<div class="wrapper">

            <section>
                <div class="section-info">
                    <h2>About Us</h2>
                        <p>blah...blah...bllah....</p>
                </div>

            </section>

    </div>

 <?php
    /* Website Footer */

    include ("include/footer.php");
?>
```

Answer: 
You want to use a collection, like `List<string>`:

```
XmlDocument doc = new XmlDocument();
doc.Load(@"D:\filter.xml");
var myList = new List<strinig>;

for (int i = 0; i < 7; i++)
{
    myList.Add(doc.SelectSingleNode("filter/f" + i).InnerText);     
}

```

Then you can use the list by referencing a string's index:

```
myValue = myList[3];

```
Use Collection to store String and this is how you can add string to collection from the XML.

```
        doc.Load(@"D:\filter.xml");
        List<string> filter = new List<string>();
        foreach (XmlNode item in doc.SelectSingleNode("filter").ChildNodes)
        {
            filter.Add(item.InnerText.ToString());
        }

```

Hope this helps.
