XML reader error

[Aaron]

The example you give me worked until I tried to open an xml file with nested tags.

for example the xml looks like this
<book>
<genre>
<action>ABC</action>
<bio>DFK</bio>
</genre>
</book>

I would like the result to be this when i select to read the <genre> tag

<action>ABC</action>
<bio>DFK</bio>

but it gives me this error

Exception: System.Xml.XmlE xception: 'Element' is an invalid node type

is there anyway to avoid this?

I need to make a script that reads the info inside a specific tag.

for example the xml file looks like this

<book genre="novel" publicationdate ="1967" ISBN="0-201-63361-2">
<title>The Confidence Man</title>
<author>
<first-name>Herman</first-name>
<last-name>Melville</last-name>
</author>
<price>11.99</price>
</book>

and say i seleted the <first-name> tag I want the output to be
Herman

THe closest example i could find is this, but it reads everything in
the xml. i want to read only the tags i choose.

You can use XmlTextReader to do this. Something like (c# code, but it
could be any .Net language)

XmlReader reader = new XmlTextReader( filename );
while ( reader.Read() )
{
if ( reader.NodeType == XmlNodeType.Ele ment )
{
string val;
switch ( reader.Name )
{
case "first-name":
val = reader.ReadElem entString();
// do something
break;
case "last-name":
val = reader.ReadElem entString();
// do something
break;
default: break;
}
}
}

Aaron,

The example you give me worked until I tried to open an xml file with nested tags.

WHAT example that WHO gave you? There are quite a number of people reading
this ...
for example the xml looks like this
<book>
<genre>
<action>ABC</action>
<bio>DFK</bio>
</genre>
</book>

I would like the result to be this when i select to read the <genre> tag

<action>ABC</action>
<bio>DFK</bio>

but it gives me this error

Exception: System.Xml.XmlE xception: 'Element' is an invalid node type

is there anyway to avoid this?
Can you post code? Your question would make a lot make sense then.

You're not making it easy for me to help you ...

What exactly are you trying to do? Write elements tags with their content?
Or is there more you're trying to do?
There are no "first-name" or "last-name" elements in the XML document that
you posted in your first email. Could that be related to your problem? Can
you point to the line where the exception occurs? I don't get an exception
when I run the sample code against the XML sample you provided.
