    <p>I have a situation to parse an XML which is having much data in attributes and levels to access the data inside the XML hierarchy.</p> <p>Confused about which parser to be used for this to be a effective approach for parsing. Parsing the XML and how to access the attributes &amp; its value.</p> <p>I was preferring DOM parser and trying to parse it but it was a little complex as i needed to get a tag -> then an attribute -> then attr value and on that condition need to get another tag access.</p> <pre><code> &lt;testCodeIdentifier classCode="ROL" &gt; &lt;realmCode code="QD" /&gt; &lt;id assigningAuthorityName="PRMKEY" extension="SJC16494" /&gt; &lt;statusCode code="active" /&gt; &lt;playingTestCodeDetails classCode="ENT" determinerCode="INSTANCE" &gt; &lt;realmCode code="QD" /&gt; &lt;id assigningAuthorityName="PRMORDCODE" extension="16494" /&gt; &lt;id assigningAuthorityName="TESTNUMINBOOK" extension="16494" /&gt; &lt;code code="16494" codeSystemName="QTIM" displayName="SureSwab Candidiasis" /&gt; &lt;name use=""&gt;&lt;/name&gt; &lt;asSeeAlsoCode classCode="ROL" &gt; &lt;realmCode code="QD" /&gt; &lt;code code="7600" displayName="Sample See Also Name" &gt;&lt;/code&gt; &lt;/asSeeAlsoCode&gt; &lt;asSeeAlsoCode classCode="ROL" &gt; &lt;realmCode code="QD" /&gt; &lt;code code="6496" displayName="Sample See Also Name" &gt;&lt;/code&gt; &lt;/asSeeAlsoCode&gt; &lt;/playingTestCodeDetails&gt; &lt;/testCodeIdentifier&gt; </code></pre> <p>Above is the sample XML in which all attributes are present as data i need to traverse them... JAXB..how can we use it????</p>

    3. COit is depend on your requirement if you want whole data at a time them better go for DOM but problem of DOM is it take huge memory for large XML file and if you want parse data in section wise then go with SAX parser both are efficient but DOM is more easier then SAX

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.
