Hi all,
I have a XML document and need just a part from it. A simple message to show on a dialog.
<document>
....
<message>Hello word</message>
....
</document>

I did :

ShowMessage(Document.FindNode('message').NodeValue)

but it returns an empty string. Showing NodeName returns 'message'.

How to get the contents of the <message> tag ???? Is it working ?

Also if we have

<tag>
<inner_tag>
.....
<inner_tag>
.....
</tag>

will NodeValue return the string between the <tag> tag ????

I've noticed that thare is no simple way to get / set that string as it is in delphi / msxml.

Regards.

The real problem is that the computer recognized that it is NOT a true "Hello World" message (word, not world) and it refused to display due to the typo ;-) just kidding.

As I recall, there's another child node in the object heiarchy when you have text between the tags. It's a "#text" subnode to the "message" node. Someone with more experience in that can expound.

If you use Lazarus, my TMPack has a XML Treeview component that loads an XML file into a TTreeView for visual display. It might you help visualize what's going on better. I've attached a tiny screenshot based on your example XML data.

No, it returns nothing, and you'll have to look for child nodes to the <tag> to find <inner_tag>.

The main problem is that you are thinking of an XML file as a text file, when in fact it's a string of interconnected objects. It's kind of like thinking of a ".frm" file textually (Is that a word) because it's stored as a text file, when in fact it's a represenation of objects that make up a form.

This is correct.
The name of the node is '#text', it's NodeValue property contains the actual text.

MsgNode:=Document.FindNode('message');
If MsgNode.FirstChildNil then
  MsgText:=MsgNode.FirstChild.NodeValue;

Should do more or less what you expect.
