AS3 help?

I have XML file with data and I am loading this to text filed.

How can check the length of values (like value1, value2…)? And

The text field has to accept only 20 chars from each value.  If it’s more than 20 chars then it should remove (delete) 21, 22 …. chars.

XML code:

<?xml version="1.0" encoding="utf-8" ?>

<data>

<Header1>        

<option>

<value1> Adobe Photoshop</value1>

<value2> Adobe Flash Professional </value2>

<value3> Adobe Acrobat Professional </value3>

<value4> Adobe Premiere Pro </value1>

</option>

</Header1>

</data>

Please help me!

Thanks

You can use string.substr(start, length) to do what you need.

ie:

myTextField.text = myValue.substr(0, 20);

Will place the first 20 chars of myValue into the field.

You might be better off writing the xml differently, so that it contains two parameters for each node... the link and the text.  Otherwise you will have to write a bit of code to isolate the two if you want to have the entire link intact but the text reduced to 20 characters at most.

Look at the String class and the properties and methods that support it.  You can use the length property (String.length) to determine how many characters are in the String.  And you can use the slice() or substr() method to capture a particular section of the String for appending to the TextField.
