John C is the closest  but XPath is case sensitive  so the correct XPath would be    bla a contains  prop   Foo

Have you tried something like     a contains  prop   Foo     I ve never used the contains function before but suspect that it should work as advertised

try this     a contains  prop  foo     that should work for any  a  tags in the document

descendant-or-self    contains  prop  Foo      Or    bla a contains  prop  Foo      Or    bla a position    lt   3    Dissected   descendant-or-self     The Axis - search through every node underneath and the node itself  It is often better to say this than     I have encountered some implementations where    means anywhere  decendant or self of the root node   The other use the default axis     or  bla a   The Tag - a wildcard match  and  bla a is an absolute path    contains  prop  Foo    or  position    lt   3    The condition within       prop is shorthand for attribute  prop  as attribute is another search axis  Alternatively you can select the first 3 by using the position   function

This XPath will give you all nodes that have attributes containing  Foo  regardless of node name or attribute name     attribute    contains     Foo         Of course  if you re more interested in the contents of the attribute themselves  and not necessarily their parent node  just drop the        attribute    contains     Foo

a contains  prop  Foo      Works if I use this XML to get results back    lt bla gt    lt a prop  Foo1  gt a lt  a gt    lt a prop  Foo2  gt b lt  a gt    lt a prop  3Foo  gt c lt  a gt    lt a prop  Bar  gt a lt  a gt   lt  bla gt    Edit   Another thing to note is that while the XPath above will return the correct answer for that particular xml  if you want to guarantee you only get the  a  elements in element  bla   you should as others have mentioned also use   bla a contains  prop  Foo      This will search you all  a  elements in your entire xml document  regardless of being nested in a  blah  element    a contains  prop  Foo        I added this for the sake of thoroughness and in the spirit of stackoverflow
