我已经弄清楚为什么参考验证失败了。不幸的是，我无法弄清楚该怎么做。
将“sigString”字符串变量解析为“doc”Document变量时，LINEFEED字符将转换为SPACE字符。我通过手动生成摘要值并将其与Java代码计算的值进行比较来证实了这一点。
在将XML字符串解析为org.w3c.dom.Document变量时，是否有人知道如何保留LINEFEED字符？
我正在尝试编写一些Java代码来验证SAML响应的XML数字签名。我已经使用其他工具验证了SAML响应，因此我知道它是有效的（不包括时序问题，而不是数字签名的因素）。下面是我使用的代码，我认为应该能够进行此验证以及我试图验证的签名。
当我运行代码时，我得到以下输出
Signature 0:
..Signature failed core validation
....signature validation status: true
....ref[0, #id14167335278088961501144300] validation status: false
Signature 1:
..Signature passed core validation
....signature validation status: true
....ref[0, #id141673352781342501524143644] validation status: true
我不知道为什么参考id14167335278088961501144300的摘要没有验证。谁能说清楚我做错了什么？
注意：我在此示例中从URL加载XSD，因此我不必在我的问题中包含4个XSD文件。但是，因此，该程序可能需要一分钟才能运行。我知道使用本地XSD文件可以消除这种减速，用发布的代码做这种方式是不可行的
