Question

我有一个xml响应，我希望从该xml响应中提取该XML的Saml Token内容，但内容嵌套在xsi：type =“ xsd：string”>下，我无法提取

我在xpath表达式下面写了 // * [local-name（）='ExecuteAuthnRequestResult'] 但是它在ExecuteAuthnRequestResult标签下提供了所有内容，我只需要SamlToken

我希望从此xml中提取Saml Token内容，但是内容嵌套在xsi：type =“ xsd：string”>下，我无法提取

Answer 1

我知道这个xpath更大。

因此，基本上，您必须使用substring-berfore和substring-after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>')

屏幕截图：

输出：
