How Can I Get The Element Id From Xml Parse In Google Apps Script

August 30, 2023 Post a Comment

Xml Code

Display name

Solution 1:

You want to retrieve 123 and 160 from the following xml data.

<directory><fieldset><fieldid="displayName">Display name</field></fieldset><employees><employeeid="123"><fieldid="displayName">John Doe</field></employee><employeeid="160"><fieldid="displayName">Jane Doe</field></employee>

You want to achieve this using XmlService of Google Apps Script.

Modification point:

In your case, roots retrieves employee. So using this, you can retrieve the attribute of id.

Modified script:

When above xml data is used, the sample script is as follows. In this sample, </employees></directory> is added to the sample xml data.

functionmyFunction() {
  const xml = `<directory>
  <fieldset>
    <field id="displayName">Display name</field>
  </fieldset>
  <employees>
    <employee id="123">
      <field id="displayName">John Doe</field>
    </employee>
    <employee id="160">
      <field id="displayName">Jane Doe</field>
    </employee>
  </employees>
</directory>`;
  var document = XmlService.parse(xml);
  var roots = document.getRootElement().getChild('employees').getChildren();
  var ids = roots.map(e => e.getAttribute("id").getValue());
  console.log(ids);  // [123, 160]
}

Note:

In this case, please use the script with V8.
If you want to retrieve both id of employee and the value of field, you can also use the following script.
```
var ids = roots.map(e => ({id: e.getAttribute("id").getValue(), name: e.getChild("field").getText()}));
```
- In this case, [ { id: '123', name: 'John Doe' }, { id: '160', name: 'Jane Doe' } ] is retrieved.
When the structure of above xml sample data is different from your actual data, the modified script might not work. So please be careful this.

Reference:

getAttribute(name)

Solution 2:

(function() {
   var roots =document.getElementsByTagName("employees")[0].children;
   
   for(k=0;k<roots.length;k++){
    var id=roots[k].getAttribute("id")
    console.log(id);
   
   }
   
   

})();
