Hallo,
ich soll die Daten von einer xml-Datei auslesen und die Eigenschaften von den Elementen in ein page auflisten.
Durch mein Code kann man die Daten schon auslesen und in einer liste speicher. Aber Daten Bindung funktioniert leider nicht. Bitte um Hilfe..
Meine Klassen:
[XML]<?xml version="1.0" encoding="iso-8859-1" ?>
<BOOK>
<TABLE>
<TABLE-PRE ID="sinceBook">
<NAME>sinceBook</NAME>
</TABLE-PRE>
</TABLE>
<TABLE>
<TABLE-PRE ID="actionBook">
<NAME>actionBook</NAME>
</TABLE-PRE>
<TABLEGR COLS="2">
<COLSPE COLNUM="1" COLWIDTH="4.31*" COLNAME="col1"/>
<COLSPE COLNUM="2" COLWIDTH="1.00*" COLNAME="col2"/>
<TD>
<ROW>
<ENTRY COLNAME="col1">
<P>Name</P>
</ENTRY>
<ENTRY COLNAME="col2">
<P>Author</P>
</ENTRY>

</TD>
<BODY>
<ROW>
<ENTRY COLNAME="col1">
