You can use CDATA to handle "&". However, you need to post some code to demonstrate exactly what you are trying to do.

Your code appears to be okay. However, your error may be based on your XML document structure. You need to post the error message!
Also, if you are using ASP.NET, you need to give ASP.NET the permission to write the file to the host server's file system.

Thnak you very you solved my problem

Personally, I'd use something like SkeletonCrew[^] to build an XML serializable model, so that you can program against objects that mirror your XML structure. Deserialize the XML to objects, make whatever changes you need to do, and then serialize it back out to XML. Much quicker and easier than trying to do inserts with the XML DOM, and more flexible than being tied to DataSet, and it sticks to your model structure unlike the DataSet.

Hello,
I have an XML file of some network topology. The network elements are nested within each other. I want to read that XML file into a newly created Access databasea file. I dont have the schema of that XML file.
Thanks for Any help.

There may be an easier way, but the only thing I can think of is to build a little executable to process the XML and do the inserts for you. I'd use something like SkeletonCrew[^] to build an XML serializable model from your XML structure, so that you can program against objects that mirror your XML structure. It would make reading the XML data much easier. Then you just have to worry about your inserts as you work through the object structure.
I don't know of an existing tool that would do it for you, I'm affraid you'd have to build something to do it.

Use the COM object of Microsoft.
Check your VB references for "Microsoft XML".

Hey 
So I have a XML with DataSet in it, in the DataSet I have 2 DataTables, in each DataTable I have a Unique ID, and I did to this row, auto-inc, and don't allow DBNull, and it's readonly.
So when I try to do NewRow(), and add it without setting the ID column, it throws an Exception DataColumn 'ID' can't allow DBNull.
So how can I do it as UNIQUE ID? do I need to allow DBNull?
|
|
|
|
|
Unique ID is similar to a primary key in some ways. It doesn't allow null. If you need nulls, you should use a regular data type with a more advanced constraint.
Keep in mind that XSD uinque IDs are document (DataSet) unique, not table unique.
|
|
|
|
|
But how can I insert a row in the DataTable with a unique ID (the next that should be)?
like if i have 5 rows and IDs 1-5, how can I add a new row with ID = 6? when it's readonly (can't edit it) and doesn't allow nulls?
|
|
|
|
|
If whatever component you're using to manipulate the XML doesn't automatically manage unique IDs, your best bet is probably to use int fields for your IDs and use a library function to manage this.
It's easy enough to write your own, although this is a well-solved problem so there's most likely one in whatever system you're running. Basically, you just need to store the next ID for each table, and write a function to retrieve it and increment each time.

Hi,
I wrote a program to extract part of XML elements, fill in the dataset with extracted elements,and display them in dataGridView (C++).e.g. : to extract only ADDRESSES and display the Id,Street,Postcode, city and country as the table columns in dataGridView
<MEMBER>
<GENDER>FEMALE</GENDER>
<AGE>35</AGE>
- <ADDRESSES>
- <ADDRESS>
<ID>1</ID>
<STREET>cranbrook ave</STREET>
<POSTCODE>1231231</POSTCODE>
<CITY>NOTTINGHAM</CITY>
<COUNTRY>UK</COUNTRY>
</ADDRESS>
- <ADDRESS>
<ID>2</ID>
<STREET>Wisteria Lane</STREET>
<POSTCODE>2452434</POSTCODE>
<CITY>FAIRVIEW</CITY>
<COUNTRY>US</COUNTRY>
</ADDRESS>
</ADDRESSES>
</MEMBER>
I have done the extraction with Xpath, append the extracted xml results node list with Stringbuilder and display them first in a text box. Then a dataset read the text box and display the result in dataGridView.
However, i would like to enable users edit the dataGridView and save the changes to the original Xml file. Could anyone suggest how I could get around it? I am a newbie in XML and I am sorry if it's a trivia >_<
Many thanks in advance,
Shar

Take a look at System.Data.DataSet.ReadXml(...) and then binding the appropriate tables to the DataGridView object.

Hello,
Many thanks for you reply  I managed to display the extracted element (addresses) in DataGridView (binded to dataset that contains <ADDRESSES>) fine, but could not figure out a way to update the original xml file if the dataGrid is updated.
For example, I have the following in "addressTry.xml" :
<MEMBER>
<GENDER>FEMALE</GENDER>
<AGE>35</AGE>
- <ADDRESSES>
- <ADDRESS>
<ID>1</ID>
<STREET>cranbrook ave</STREET>
<POSTCODE>1231231</POSTCODE>
<CITY>NOTTINGHAM</CITY>
<COUNTRY>UK</COUNTRY>
</ADDRESS>
</ADDRESSES>
when user changes CITY to LONDON, the DataSet is updated. But I could not use DataSet.WriteXml(...) or XmlDataDocument.Save(..) to update original file as this will overwrite the whole xml file. i.e : the <MEMBER>,<GENDER>,<AGE> and their child elements will be deleted, replaced by only <ADDRESSES> elements from dataset.
So how could I update this to the original file (so only <ADDRESSES> element is affected, and <MEMBER>, <GENDER> and <AGE> stay the same?)
Many thanks for advice and suggestions,
Shar
