Inserting something in variable

I have the whole thing stored in variable. when I receive this, I need to append the path to token which token I wish. path is path=/; domain=.myorg.com ;

WasToken=AAECAzREQjgyNTY3NERCODI2Q0Zjbj1zYmswMi9vdT1iaG5zbS9vdT1pc2hzZy9vdT1kaXZhZG1pbi9vPWRvaANcWzW6mcn5IzHXtLr+BuYEMPTX; sessiontoken=DstTDbgX0ydK/nAixEvkBQCHrZ5CAar2DGq55U0Mo/6ll1+XEad3/cWyeXdO6hwmBePreLIW5d4CaoxiZHMEwuI5faG1j0UeRNizNJAw8JqEI0HuhpdpY5qSO46Iz+8WffmQoyemD/eQnWMkCeJbMwMHGIebSh7Q9mfC7wqoMqr+28IoeOYM93pPqVVwTiGOXEmiWdcp1S6WTKyw17E06S0GDlLA8eZlFFxFksgGtQiqsmp2vevWvz2dpmYYUPZ6TK3+vsNjkV2urGj24DHIrFGgU5J2eJq9qNEdEAtsuH71TJ6R0pyVK6h4FpaT1p5KurkdAZlIOl/Rpuzw2rnDNVJgW4PzWkeKIjoDDhlUhZ2cM4nNBoHqMGCz2HkwwbU72QVTzzXgwhOXtjrUlaaoZA==; WasToken=AAECAzREQjgyNTY3NERCODI2Q0Zjbj1zYmswMi9vdT1iaG5zbS9vdT1pc2hzZy9vdT1kaXZhZG1pbi9vPWRvaANcWzW6mcn5IzHXtLr+BuYEMPTX; NonceToken=61AF4E4A72A6749A8525787E0071880F; spikerAcceptLanguages=en-us%2Cen%3Bq%3D0.5; spikerStringLocale=en; spikerStyleLocale=en

In the above thing I want to append path to WasToken wherever it is repeating so after appending path it must become

WasToken=AAECAzREQjgyNTY3NERCODI2Q0Zjbj1zYmswMi9vdT1iaG5zbS9vdT1pc2hzZy9vdT1kaXZhZG1pbi9vPWRvaANcWzW6mcn5IzHXtLr+BuYEMPTX; path=/; domain开发者_JAVA技巧=.myorg.com ; sessiontoken=DstTDbgX0ydK/nAixEvkBQCHrZ5CAar2DGq55U0Mo/6ll1+XEad3/cWyeXdO6hwmBePreLIW5d4CaoxiZHMEwuI5faG1j0UeRNizNJAw8JqEI0HuhpdpY5qSO46Iz+8WffmQoyemD/eQnWMkCeJbMwMHGIebSh7Q9mfC7wqoMqr+28IoeOYM93pPqVVwTiGOXEmiWdcp1S6WTKyw17E06S0GDlLA8eZlFFxFksgGtQiqsmp2vevWvz2dpmYYUPZ6TK3+vsNjkV2urGj24DHIrFGgU5J2eJq9qNEdEAtsuH71TJ6R0pyVK6h4FpaT1p5KurkdAZlIOl/Rpuzw2rnDNVJgW4PzWkeKIjoDDhlUhZ2cM4nNBoHqMGCz2HkwwbU72QVTzzXgwhOXtjrUlaaoZA==; WasToken=AAECAzREQjgyNTY3NERCODI2Q0Zjbj1zYmswMi9vdT1iaG5zbS9vdT1pc2hzZy9vdT1kaXZhZG1pbi9vPWRvaANcWzW6mcn5IzHXtLr+BuYEMPTX; path=/; domain=.myorg.com ; NonceToken=61AF4E4A72A6749A8525787E0071880F; spikerAcceptLanguages=en-us%2Cen%3Bq%3D0.5; spikerStringLocale=en; spikerStyleLocale=en

How to do this using xsl.

XSLT is not very good at recursion and string manipulation, and this requires both, but it is possible. Here is my solution (which may have more conditions than necessary if you can be assured of certain string patterns (e.g. if "WasToken" is always at the beginning of the string)):

<?xml version="1.0" encoding="UTF-8"?>

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

  <xsl:output method="text" />
