Get all attributes, XPATH

[hose]

Dear All, I am getting stuck with this for a few days :(
and about to decide to give up or find an alternative, but I want to give it a last try :(

My question is how can we write an Xpath expression to get all attributes from an element with ID begins with "ext"

I have tried something like blow, but did not work :(

//@*[starts-with(@ID,"ext")]

Below is my XML file

<?xml version="1.0"?>
<books>
    <book ID="extension1" available="yes">
        <title>Book Title 1</title>
        <price>100 - 200</price>
    </book>
    <book ID="Book001" available="no">
        <title>Book Title 2</title>
        <price>400 - 500</price>
    </book>
    <book ID="extension2">
        <title>Book Title 3</title>
        <price>abc - 500</price>
    </book>
    <book available="soon">
        <title>Book Title 5</title>
        <price>a100 - c200</price>
    </book>
    <book ID="Book003" available="yes">
        <title>Book Title 6</title>
        <price>c100 - 200</price>
    </book>
</books>

There is a mistake in your xpath expression. The correct one is like the following:

//*[starts-with(@ID,'ext')]

If you need an example of using the xpath starts-with function in Python, see the example #2 in this http://murzal-arsya.blogspot.com/200...hon-using.html

then your expression would get all elements :), thanks

Well after getting all the needed nodes then you can select the attributes:

"//*[starts-with(@ID,'ext')]/@*"

//@*[starts-with(../@ID,'ext')]
