我正在尝试从HTTP响应中解析XML主体。

这是我想要的和我在做什么。

我制作了简单的BPMN文件，该文件是请求API并从API服务器中获取响应。

我想解析由xml组成的响应和响应。将$（xml（wendment）}放入输出值时，我可以看到所有XML数据。

<?xml version="1.0" encoding="UTF-8"?><deployment xmlns="urn:ietf:params:xml:ns:netconf:base:1.0">
  <deployment_details>
    <host_uuid>1963aa56409abe71d8c449d6e2adf3eb816e8ccf75838bfa664ef803</host_uuid>
    <host_name>my_hostname</host_name>

        <network_uuid>b76e4cd7-0d88-4889-b6fe-2430641c26cc</network_uuid>
        <gateway>172.18.21.254</gateway>
        <ip_address>172.18.21.132</ip_address>

      </interface>
    </interfaces>
  </deployment_details>
  <deployment_name>info-csr-test</deployment_name>
</deployment>

最终目标是获取主机名 /部署/deployment_details/host_name 至于此，我将值按以下值进行

${XML(response).xPath("/deployment/deployment_details/host_name").element()}

了实例化定义ESC_API_TEST：12：782EB51A-D4EC-111EC-AB99-5AF27468B181：错误在评估表达式时发生错误：$ {xml（wespmence）.xpath（XPath）.xpath（“/exployment/exployment/deployment_detail_details/osthost host_name_name”））。元素（）}。原因：org.camunda.spin.xml.spinxpathexception：spin/dom-xml-01035无法找到xpath expression'/exployment/deployment_details/host_name'[start-instance-error]

有人会帮助我的问题吗？

原文

I'm trying to parsing xml body from http response.

Here is what I want and what I'm doing.

I made simple bpmn file which is request api and get the response from api server.

I want to parsing the response and response consist of xml.
I can see the all xml data when I put the $(XML(response)} in output value.

<?xml version="1.0" encoding="UTF-8"?><deployment xmlns="urn:ietf:params:xml:ns:netconf:base:1.0">

    </interfaces>
  </deployment_details>
  <deployment_name>info-csr-test</deployment_name>
</deployment>

final goal is to get the hostname
/deployment/deployment_details/host_name
As for this I put the value as below

${XML(response).xPath("/deployment/deployment_details/host_name").element()}

Cannot instantiate process definition esc_api_test:12:782eb51a-d4ec-11ec-ab99-5af27468b181: Error while evaluating expression: ${XML(response).xPath("/deployment/deployment_details/host_name").element()}. Cause: org.camunda.spin.xml.SpinXPathException: SPIN/DOM-XML-01035 Unable to find XPath expression '/deployment/deployment_details/host_name' [ start-instance-error ]

Does someone help my issue?
