获取SVG的border-radius

Question

有没有办法获得/找到SVG的边界半径？

具体来说，圆角。

示例：

＆＃13;

＆＃13;

   #!/usr/bin/env ruby


    require 'rubygems'

    regexen=''

    file = 'main.log'
    replace_file = 'clean.log'
    logfile_du = File.open(file, mode='r')

    params_file = File.open(replace_file,mode='r')
    i=1
    File.readlines('main.log').each do |line1|

    print "#{i}\n"
    line1.chomp!
    File.readlines('clean.log').each do |line|

            line.chomp!
            regexen = /#{line}.*/


    if line1 =~ /#{regexen}/
        print "match\n"
      #  print line1
    else
      print "no_match\n"

    end
    end

    i=i+1
    end

＆＃13;
