How do I select child elements of any depth using XPath?

Question

Suppose I have this (simplified):

Answer 1

You're almost there. Simply use:

//form[@id='myform']//input[@type='submit']

The // shortcut can also be used inside an expression.

Answer 2

If you are using the XmlDocument and XmlNode.

Say:

XmlNode f = root.SelectSingleNode("//form[@id='myform']");

Use:

XmlNode s = f.SelectSingleNode(".//input[@type='submit']");

It depends on the tool that you use. But .// will select any child, any depth from a reference node.

Answer 3

Also, you can do it with css selectors:

form#myform input[type='submit']

space beween elements in css elector means searching input[type='submit'] that elements at any depth of parent form#myform element

Answer 4

//form/descendant::input[@type='submit']
