.net - Finding all nodes without any text node -

-

with xpath (.net), i'm trying select nodes don't contain text node.

given document:

<root>   <node1>     <node1a>node 1a</node1a>   </node1>   <node2>node 2</node2>   <node3>     <node3a>node 3a</node3a>     <node3b></node3b>   </node3>   <node4></node4>   <node5>     <node5a></node5a>   </node5> </root>

i'm tyring nodes:

<node3b></node3b>  <node4></node4>  <node5>   <node5a></node5a> </node5>

note overlapping subtrees merged, node5a should not returned separately.

i expect pull trick, reason (which obvious when points out) doesn't:

//*[count(//text()) = 0]

note: i'm using xpath tester try things out.

assuming result example want (which not totally in accordance statement in title) suggestions above

//*[count(.//text()) = 0]

or preferred way

//*[not(.//text())]

doesn't work result not expected

<node3b /> <node4 /> <node5>   <node5a /> </node5> <node5a /> <!-- node not present in example -->

if want subtrees without text node not included in other resulting subtrees solution 1 

//*[not(.//text())][not(ancestor::*[not(.//text())])]

the second predicate remove result nodes has @ least 1 ancestor included in result

-
i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
