ruby - Moving a node as the first child of another node -


i have document:

<html>  <head>    <style>some styles<style>  </head>  <body>    <h1>header</h1>    <table>table content</table>    <div>some text</div>  </body> </a>

the below code moves <style> tag below <div> in <body>:

  style  = @doc.at_css "style"   body = @doc.at_css "body"   style.parent = body

is there way move <style> above <h1>?

finding first child of body , adding style tag previous sibling first child solves problem.

  style  = @doc.at_css "style"   body = @doc.at_css "body"   style.parent = body    first_child = body.first_element_child   first_child.add_previous_sibling(style)

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds
