Traversing XML Doc

Question

I have an XML Document as follows
<?xml version="1.0" encoding="ISO-8859-1" ?>
<WebInfo>
<Prj>
<Name>TEST</Name>
<Version>0.5</Version>
</Prj>
<!-- === Db Specific Info === -->
<Database name="Db1">
<!-- Min pool size -->
<minPoolSize>10</minPoolSize>
<!-- Database password -->
<password>pass1</password>
<!-- Database login name -->
<loginname>log1</loginname>
</Database>
<Database name="Db2">
<!-- Min pool size -->
<minPoolSize>15</minPoolSize>
<!-- Database password -->
<password>pass2</password>
<!-- Database login name -->
<loginname>log2</loginname>
</Database>
</WebDialog>
I can extract the Prj information ok, by doing the following (in Java):
System.out.println ( xmlDoc.valueOf("//Prj/Name") );
Now I want to extract the Database information. I can get each db name by doing the following:
NodeList aDBs = xmlDoc.selectNodes("//Database");
for (int a=0; a< aDBs.getLength(); a++)
XMLElement aDBElement = (XMLElement)aDBs.item(a);
String DBAlias = aDBElement.getAttribute("name");
System.out.println ("DBNAME = " + DBAlias);
} // for
... but how do I obtain the other information about the database e.g loginname and password?
I'm completely stuck at the moment, and basically guessing, and getting nowhere.
Any info would be gratefully appreciated.
Thanks,
Andy

You're 95% of the way there.
// More efficient to avoid "//" if possible
NodeList aDBs = xmlDoc.selectNodes("/WebInfo/Database");
// More efficient to not call getLength() each time
int matches = aDBs.getLength();
for (int a=0; a < matches; a++)
XMLElement aDBElement = (XMLElement)aDBs.item(a);
String DBAlias = aDBElement.getAttribute("name");
System.out.println ("DBNAME = " + DBAlias);
// Use valueOf() of the aDBElement current node
String minPoolSize = aDBElement.valueOf("minPoolSize"); // Relative XPath expr
String username = aDBElement.valueOf("username"); // Relative XPath expr
// etc.
} // for
