    <p>I am trying to parse the following XML:</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;!-- _tag --&gt; &lt;tag value="0" actions_tagged="0" name="adjust temperature"&gt; &lt;link type="application/xml" rel="list" href="/api/v1/tags.xml"/&gt; &lt;link type="application/xml" rel="self" href="/api/v1/tags/adjust%20temperature.xml"/&gt; &lt;actions&gt; &lt;action id="105"&gt; &lt;link type="application/xml" rel="tagged_action" href="/api/v1/actions/105.xml"/&gt; &lt;short_name&gt;Set thermostat to 68F in the winter and 74F in the summer&lt;/short_name&gt; &lt;/action&gt; &lt;action id="106"&gt; &lt;link type="application/xml" rel="tagged_action" href="/api/v1/actions/106.xml"/&gt; &lt;short_name&gt;Close windows and blinds&lt;/short_name&gt; &lt;/action&gt; &lt;/actions&gt; &lt;/tag&gt; </code></pre> <p>I would like to capture each "action id" and each "short name". I'm able to capture the short name with the following code. But, how do you obtain the corresponding action id?</p> <pre><code>String action = null; DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance(); DocumentBuilder db = dbf.newDocumentBuilder(); Actions myActions = new Actions(); InputSource inStream = new InputSource(); inStream.setCharacterStream(new StringReader(xml)); Document doc = db.parse(inStream); NodeList nodeList = doc.getElementsByTagName("action"); for (int s = 0; s &lt; nodeList.getLength(); s++) { Node fstNode = nodeList.item(s); if (fstNode.getNodeType() == Node.ELEMENT_NODE) { Element fstElmnt = (Element) fstNode; NodeList lstNmElmntLst = fstElmnt.getElementsByTagName("short_name"); Element lstNmElmnt = (Element) lstNmElmntLst.item(0); NodeList lstNm = lstNmElmnt.getChildNodes(); String currentAction = ((Node) lstNm.item(0)).getNodeValue(); if(currentAction != null) { myActions.setShort_name(currentAction); } lstNmElmntLst = fstElmnt.getElementsByTagName("action id"); // this didn't work - nor did 'id' lstNmElmnt = (Element) lstNmElmntLst.item(0); lstNm = lstNmElmnt.getChildNodes(); currentAction = ((Node) lstNm.item(0)).getNodeValue(); if(currentAction != null) { myActions.setDescription(currentAction); } } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
