我得到了xml，它是使用xslt函数json-to-xml（）生成的。我需要使用给定的xpath更新此xml，如结果xml中所示。我需要java或xslt中的解决方案。任何帮助将非常感激。

我的尝试
我尝试使用xslt函数将此xml转换回json，然后使用com.jayway.jsonpath Jayway JsonPath库来解析/更改给定xpath上的json值。然后最后使用xslt函数将json再次更改为xml。这对我来说就像魅力一样！
但在使用这个库后，我开始在我的应用程序的其他部分面临问题:(。所有json请求主体的发布请求开始给出400错误。错误是＆＃34;错误400客户端发送的请求在语法上不正确＆＃ 34;我无法弄清楚这个问题，可能是因为不同的罐头问题。
所以我正在尝试其他一些工作方式。还有像Jayway JsonPath这样的其他图书馆吗？或任何其他解决方案/建议将有助于很多。
