在变量中插入一些东西

Question

我将所有内容存储在变量中。当我收到此消息时，我需要将路径附加到我想要的令牌。 路径是路径=/；域名=.myorg.com ；

WasToken=AAECAzREQjgyNTY3NERCODI2Q0Zjbj1zYmswMi9vdT1iaG5zbS9vdT1pc2hzZy9vdT1kaXZhZG1pbi9vPWRvaANcWzW6mcn5IzHXtLr+BuYEMPTX; sessiontoken=DstTDbgX0ydK/nAixEvkBQCHrZ5CAar2DGq55U0Mo/6ll1+XEad3/cWyeXdO6hwmBePreLIW5d4CaoxiZHMEwuI5faG1j0UeRNizNJAw8JqEI0HuhpdpY5qSO46Iz+8WffmQoyemD/eQnWMkCeJb MwMHGIebSh7Q9mfC7wqoMqr+28IoeOYM93pPqVVwTiGOXEmiWdcp1S6WTKyw17E06S0GDLA8eZlFFxFksgGtQiqsmp2vevWvz2dpmYYUPZ6TK3+vsNjkV2urGj24DHIrFGgU5J2eJq9qNEdEatsu H71TJ6R0pyVK6h4FpaT1p5KurkdAZlIOl/Rpuzw2rnDNVJgW4PzWkeKIjoDDhlUhZ2cM4nNBoHqMGCz2HkwwbU72QVTzzXgwhOXtjrUlaaoZA==； WasToken=AAECAzREQjgyNTY3NERCODI2Q0Zjbj1zYmswMi9vdT1iaG5zbS9vdT1pc2hzZy9vdT1kaXZhZG1pbi9vPWRvaANcWzW6mcn5IzHXtLr+BuYEMPTX; NonceToken=61AF4E4A72A6749A8525787E0071880F； spinkerAcceptLanguages=en-us%2Cen%3Bq%3D0.5; spinkerStringLocale=zh; spinkerStyleLocale=en

在上面的事情中，我想将路径附加到 WasToken 的任何重复位置，因此在附加路径之后，它必须变成

tLr+BuYEMPTX；路径=/；域名=.myorg.com ； sessiontoken=DstTDbgX0ydK/nAixEvkBQCHrZ5CAar2DGq55U0Mo/6ll1+XEad3/cWyeXdO6hwmBePreLIW5d4CaoxiZHMEwuI5faG1j0UeRNizNJAw8JqEI0HuhpdpY5qSO46Iz+8WffmQoyemD/eQnWMkCeJb MwMHGIebSh7Q9mfC7wqoMqr+28IoeOYM93pPqVVwTiGOXEmiWdcp1S6WTKyw17E06S0GDLA8eZlFFxFksgGtQiqsmp2vevWvz2dpmYYUPZ6TK3+vsNjkV2urGj24DHIrFGgU5J2eJq9qNEdEatsu H71TJ6R0pyVK6h4FpaT1p5KurkdAZlIOl/Rpuzw2rnDNVJgW4PzWkeKIjoDDhlUhZ2cM4nNBoHqMGCz2HkwwbU72QVTzzXgwhOXtjrUlaaoZA==； WasToken=AAECAzREQjgyNTY3NERCODI2Q0Zjbj1zYmswMi9vdT1iaG5zbS9vdT1pc2hzZy9vdT1kaXZhZG1pbi9vPWRvaANcWzW6mcn5IzHXtLr+BuYEMPTX;路径=/；域名=.myorg.com ； NonceToken=61AF4E4A72A6749A8525787E0071880F； spinkerAcceptLanguages=en-us%2Cen%3Bq%3D0.5; spinkerStringLocale=zh; spinkerStyleLocale=en

如何使用 xsl 执行此操作。

Answer 1

XSLT 不太擅长递归和字符串操作，而这两者都需要，但这是可能的。这是我的解决方案（如果您可以确定某些字符串模式（例如，如果“WasToken”始终位于字符串的开头），则可能有比必要的更多的条件）：
