Question

我将整个事物存储在变量中。当我收到这个时，我需要将路径附加到我想要的令牌。 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

在上面的内容中，我想在WasToken的任何地方追加路径，所以在追加路径之后它必须成为

WasToken=AAECAzREQjgyNTY3NERCODI2Q0Zjbj1zYmswMi9vdT1iaG5zbS9vdT1pc2hzZy9vdT1kaXZhZG1pbi9vPWRvaANcWzW6mcn5IzHXtLr+BuYEMPTX; path=/; domain=.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

如何使用xsl执行此操作。

Answer 1

XSLT在递归和字符串操作方面不是很好，这需要两者，但它是可能的。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），则可能有更多不必要的条件））：
