XPath: returning the index of specific tag inside a set of tags with the same type -

-

here excerpt of xml:

<table>     ...     <tbody>     <tr>         <td></td>         <td></td>         <td></td>     </tr>     <tr>         <td></td>         <td></td>         <td></td>     </tr>     </tbody> </table>

i know how find specific <tr> tag.

is possible define <tr> tag index or ordinal number inside <tbody> tag? guess, it's possible loop through table, table quite large , take lots of time.

is possible index/ordinal number single xpath statement?

i've used following xpath expression:

//tbody//td[text()='findme']/../following-sibling::tr

these expression calculates, how many 'tr' nodes located under node 'findme' text. actually, useful, because quantity of 'tr' nodes obtained.

but, prior given xpath, verification should made, because in case 'finme' string absent, xpath return 0. following expression works validation fine:

//tbody//td[text()='findme']

python - TypeError: can only concatenate tuple (not "float") to tuple -

-
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...
