How to Extract the value of a Value Attribute in Option Tag?

Question

 Hi,

I am new to VSTS2008,I want to extract the value of Value Attribute of Option tags.

For example:

On a web page there are five different Select tags and under that different options.

For first select tag code is as follows:

<Select name='CboOne'...>
 <Option value='12'>First</Option>
 <Option selected='selected' value='13'>Second</Option>
</Select>
For second tag
<Select name='CboSecond'>
<Option value='14'>Third</Option>
<Option selected='selected' value='15'>Fourth</Option>

And so on..

Is there any way to extract the 13 and 15 from value attribute of selected options?

Hello,

If the  default extraction rules are not good for this you need to write Custom Extraction Rule.

Here is a screencast about creating custom extraction rule - Team System – How to Create Custom Extraction Rule [HE] - Screencast

And here is an article from msdn - How to: Create a Custom Extraction Rule

Hi,

I have tried that one also but it is working only for first Select Tag options.

It is not working for second Select tag options.

I mean to say i am able to identify the second Select tag in the code by it's name attribute, but there is no way to uniquely identify the Option tag under specific Select tag.

 For my given example:

Custom extraction rule always returns me 13,even if i am checking the Select tag name before execution of extraction method.
For Second Select Tag it is returning me options of First Select Tag.

Hello,

Can you please post your custom extraction rule code.

There is no reason why you can't any value from the Selct tag!

HI,
 
This is the class.
I am passing the name of the select tag in Name property.
And Option in the OptionName property.
