When the xml is having "xmlns="urn:hl7-org:v3" then the xpath query doesnt get me the data. For supressing that i have written the code in java and removed the line from XML.</p> <p>I need to parse the XML and get the data without deleting the namespace part from the XML. Is this a problem related to xsd or it is not getting the xsd mentioned?</p>

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
