Question

我在我的项目中使用Jquery。我有以下xml响应：

<?xml version="1.0" encoding="UTF-8"?>
<details>
   <company>
      <company-name>abc</company-name>
      <employee>
         <employee-name>John</employee-name>
      </employee>
      <employee>
         <employee-name>Steve</employee-name>
      </employee>
   </company>
   <company>
      <company-name>xyz</company-name>
      <employee>
         <employee-name>Robert</employee-name>
      </employee>
      <employee>
         <employee-name>Stephen</employee-name>
      </employee>
   </company>
</details>

现在，我想检索<company>为<company-name>的{{1}}的信息，包括其下的所有子雇员（xyz）。我认为我必须使用<employee>。有人可以帮我吗？

Answer 1

您需要结合使用$.parseXML和.find()方法。

要根据文本查找特定的节点，可以使用jQuery :contains()选择器

const data = `<?xml version="1.0" encoding="UTF-8"?><details><company><company-name>abc</company-name><employee><employee-name>John</employee-name></employee><employee><employee-name>Steve</employee-name></employee></company><company><company-name>xyz</company-name><employee><employee-name>Robert</employee-name></employee><employee><employee-name>Stephen</employee-name></employee></company></details>`;

let company = $($.parseXML(data)).find('company-name:contains(xyz)').parent();
console.log('Company: ' + company.find('company-name').text());

company.find('employee').each(function() {
  console.log('Employee: ' + $(this).find('employee-name').text());
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

Answer 2

您可以执行以下操作：

var exampleString = "xyz"
var employees = $(XMLdata).find("company-name:contains(" + exampleString + ")").nextAll("employee");
$.each(employees, function() {
  console.log($(this).find("employee-name").text())
});

在下面的演示中查看工作示例：

var XMLdata = $.parseXML('<?xml version="1.0" encoding="UTF-8"?><details>   <company>      <company-name>abc</company-name>      <employee>         <employee-name>John</employee-name>      </employee>      <employee>         <employee-name>Steve</employee-name>      </employee>   </company>   <company>      <company-name>xyz</company-name>      <employee>         <employee-name>Robert</employee-name>      </employee>      <employee>         <employee-name>Stephen</employee-name>      </employee>   </company></details>');

var exampleString = "xyz"
var employees = $(XMLdata).find("company-name:contains(" + exampleString + ")").nextAll("employee");
$.each(employees, function() {
  console.log($(this).find("employee-name").text())
});

根据条件使用Jquery检索子节点信息
