需要来自 XML 的 Saml Auth Token Xml xpath 表达式

Question

我有一个 xml 响应，从那个 xml 响应我希望从这个 xml 中提取 Saml 令牌内容，但内容嵌套在 xsi:type="xsd:string"> 我无法提取

下面我写了xpath表达式 //*[本地名称() = 'ExecuteAuthnRequestResult'] 但它提供了 ExecuteAuthnRequestResult 标签下的所有内容，我只需要 SamlToken

我想从此 xml 中提取 Saml 令牌内容，但内容嵌套在 xsi:type="xsd:string"> 下，我无法提取

Answer 1

我知道这个 xpath 有点大。

所以基本上你必须使用 substring-berfore 和 substring-after 来获取令牌字符串。下面是 xpath

substring-before(substring-after(//*[local-name() = 'ExecuteAuthnRequestResult'] /text(),'<saml:AttributeValue xsi:type="xsd:string">'),'</saml:AttributeValue>')

输出：
