XmlService

This service allows scripts to parse, navigate, and programmatically create XML documents.

// Log the title and labels for the first page of blog posts on the
// Google Workspace Developer blog.
function parseXml() {
  const url = 'https://gsuite-developers.googleblog.com/atom.xml';
  const xml = UrlFetchApp.fetch(url).getContentText();
  const document = XmlService.parse(xml);
  const root = document.getRootElement();
  const atom = XmlService.getNamespace('http://www.w3.org/2005/Atom');

  const entries = root.getChildren('entry', atom);
  for (let i = 0; i < entries.length; i++) {
    const title = entries[i].getChild('title', atom).getText();
    const categoryElements = entries[i].getChildren('category', atom);
    const labels = [];
    for (let j = 0; j < categoryElements.length; j++) {
      labels.push(categoryElements[j].getAttribute('term').getValue());
    }
    Logger.log('%s (%s)', title, labels.join(', '));
  }
}

// Create and log an XML representation of the threads in your Gmail inbox.
function createXml() {
  const root = XmlService.createElement('threads');
  const threads = GmailApp.getInboxThreads();
  for (let i = 0; i < threads.length; i++) {
    const child =
        XmlService.createElement('thread')
            .setAttribute('messageCount', threads[i].getMessageCount())
            .setAttribute('isUnread', threads[i].isUnread())
            .setText(threads[i].getFirstMessageSubject());
    root.addContent(child);
  }
  const document = XmlService.createDocument(root);
  const xml = XmlService.getPrettyFormat().format(document);
  Logger.log(xml);
}
Properties Property Type Description ContentTypes ContentType An enumeration representing the types of XML content nodes. Methods Detailed documentation createCdata(text)

Creates an unattached CDATASection node with the given value.

Parameters Name Type Description text String the value to set Return

Cdata — the newly created CDATASection node

createDocType(elementName)

Creates an unattached DocumentType node for the root Element node with the given name.

Parameters Name Type Description elementName String the name of the root Element node to specify in the DocType declaration Return

DocType — the newly created DocumentType node

createDocType(elementName, systemId)

Creates an unattached DocumentType node for the root Element node with the given name, and the given system ID for the external subset data.

Parameters Name Type Description elementName String the name of the root Element node to specify in the DocType declaration systemId String the system ID of the external subset data to set Return

DocType — the newly created DocumentType node

createDocType(elementName, publicId, systemId)

Creates an unattached DocumentType node for the root Element node with the given name, and the given public ID and system ID for the external subset data.

Parameters Name Type Description elementName String the name of the root Element node to specify in the DocType declaration publicId String the public ID of the external subset data to set systemId String the system ID of the external subset data to set Return

DocType — the newly created DocumentType node

createDocument()

Creates an empty XML document.

Return

Document — the newly created document

createDocument(rootElement)

Creates an XML document with the given root Element node.

Parameters Name Type Description rootElement Element the root Element node to set Return

getCompactFormat()

Creates a Format object for outputting a compact XML document. The formatter defaults to UTF-8 encoding, no indentation, and no additional line breaks, but includes the XML declaration and its encoding.

// Log an XML document in compact form.
const xml = '<root><a><b>Text!</b><b>More text!</b></a></root>';

// Log an XML document in human-readable form.
const xml = '<root><a><b>Text!</b><b>More text!</b></a></root>';
const document = XmlService.parse(xml);
const output = XmlService.getPrettyFormat().format(document);
Logger.log(output);
Return

Format — the newly created formatter

getRawFormat()

Creates a Format object for outputting a raw XML document. The formatter defaults to UTF-8 encoding, no indentation and no line breaks other than those provided in the XML document itself, and includes the XML declaration and its encoding.
