在变量中插入东西

Question

我把整件事都存储在变量中。当我收到这个消息时，我需要将该路径追加到我希望的令牌中。 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

在我要追加路径WasToken无论在哪里追加路径之后重复所以上述的事情它必须成为

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

如何做到这一点使用XSL。

Answer 1

XSLT在递归和字符串操作上不是很好，这需要两者，但这是可能的。这里是我的解决方案（其中可能有超过必要的条件，如果你可以放心某些字符串模式（例如，如果“WasToken”总是在字符串的开头））：

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

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