I have an ASP.NET project with a String with XML in it. The XML was created from a DataSet using ds.GetXml(). Now, I want to put the contents of the 2nd column into a listbox. How can I read the string to extract the data to put it into a dataset or directly into the listbox?

Hi Tor,
The best way is to load the XML string into an XML document and then use XPath to retrieve the information (nodes) you want, e.g.
XmlDocument xmlReceive = new XmlDocument();
if (xmlReceive != null)
{
xmlReceive.LoadXml(xmlStringFromDataSet);
XmlNodeList collResults = xmlReceive.SelectNodes("/your/xml/tag/path/here");
if (collResults != null && collResults.Count > 0)
{
for(int i=0; i < collResults.Count; i++)
{
XmlNode nodeResult = collResults[i];
if (nodeResult != null)
{
lstBox1.Items.Add(nodeResult.text);
}
}
}
}
Replace the XPath above with the one you require.
Hope this helps,
Andy

you have not actually given us your REAL code - as the template would not work "<br>" in the template should be "<br/>".
if you show us the actual code we might be able to help.

Oh, sorry. I cleaned it up a little bit before posting and that small mistake slipped in. However, I already found a solution for the problem. The following template does the trick for me:
<xsl:template name="convertlinebreaks">
<xsl:param name="text"/>
<xsl:choose>
<xsl:when test="contains($text,'&#xA;')">
<xsl:value-of select="substring-before($text,'&#xA;')"/>
<br/>
<xsl:call-template name="convertlinebreaks">
<xsl:with-param name="text">
<xsl:value-of select="substring(substring-after($text,'&#xA;'), 2, string-length(substring-after($text,'&#xA;')))"/>
</xsl:with-param>
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$text"/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
But I'd still like to know how this could be implemented using the translate() function.

In my XSL document I need to output some HTML if a node exists and it's not empty. I've tried testing it like this but it's not working:
<xsl:if test="'{Main/Whatever}' != ''"><br />
...<br />
</xsl:if>
It always goes into the if, no matter what. What's the solution?
Thanks,
Alvaro

Is Main/Whatever supposed to be the node your checking for? If so, your comparing strings, not checking to see if the node equals an empty string. I think what your looking for is:
<xsl:if test="Main/Whatever"><br />
...<br />
</xsl:if>
|
|
|
|
|
Thanks, but this only tests if the node exists. I want it to also test if it's not empty.
Regards,
Alvaro

both test can be done in one go:
<xsl:if test="string-length(Main/Whatever) > 0"><br />
...<br />
</xsl:if>

I have the following line in my XSL file:
<a href='mailto:YourFriend?Subject=I love XSL%26Body=How about you?'>Email to a Friend</a>
When I see the tranformed XML file in the IE6 browser, it shows the link just fine, and on the status bar I see it as:
mailto:YourFriend?Subject=I love XSL&Body=How about you?
The problem is that when I click on the link, I get this inside my Outlook popup:
To: YourFriend<br />
Cc: <br />
Subject: I love XSL&Body=How about you?
The message portion ends up as part of the subject. What's going on and how can I fix it?
By the way, I have to use %26 for the ampersand otherwise I get a "A semi colon character was expected." error, but I have a feeling that's part of the problem.
Thanks in advance,
Alvaro

I have the following schema, which I believe needs to be fleshed out more to make it more powerful, can someone please help and also point me in the right direction...hopefully once my project gets approved on SourceForge I will be adding this as well as something else I have to the project. Anyeverhow, here is the schema as it stands right now:
<?xml version="1.0" encoding="utf-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="student">
<xs:complexType>
<xs:sequence>
<xs:element name="stunum" type="xs:integer" />
<xs:element name="lastname" type="xs:string" />
<xs:element name="firstname" type="xs:string" />
<xs:element name="age" type="xs:integer" />
<xs:element name="dateborn" type="xs:date" />
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element name="address">
<xs:complexType>
<xs:sequence>
<xs:element name="pnum" type="xs:integer" />
<xs:element name="addnum" type="xs:integer" />
<xs:element name="street" type="xs:string" />
<xs:element name="city" type="xs:string" />
<xs:element name="country" type="xs:string" />
<xs:element name="poczip" type="xs:string" />
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
If you can make any changes to it, please do...any and all help would be very much appreciated.
Someone said the following to me as well, although I am having problems understanding what he is implying, probably because he didn't include an example:
"In your case, it depends on where you're going with this, but I'd consider creating a ComplexType for a "person" and then define your "Student" as an extension of the Person type, adding perhaps the student ID. That way, if you added Instructor, you'd be able to re-use the generalized part of the definition of a person (since Instructors and Students both have some things in common)."
If I can get this up and running, I will eventually need to be able to easily change some things in it to get it working with a second project that I have on SourceForge.

I haven't even tested if this is well formed so there might be some typos etc. but this modifed version from you schema shows the basic idea behind type extensions (or inheritance).

The schema itself was buggy as it had no root element and so on, but here's a refined version from it and below it you'll fin a sample xml-file. You still have to modify the schema so that it suites you purposes..
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">

<xs:element name="instructor" type="instructorType"></xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:complexType name="personType">
<xs:sequence>
<xs:element name="lastname" type="xs:string"></xs:element>
<xs:element name="firstname" type="xs:string"></xs:element>
<xs:element name="age" type="xs:integer"></xs:element>
<xs:element name="dateborn" type="xs:date"></xs:element>
<xs:element name="address" type="addressType"></xs:element>
</xs:sequence>
</xs:complexType>
<xs:complexType name="studentType">

<xs:extension base="personType">

<xs:element name="country" type="xs:string"></xs:element>
<xs:element name="poczip" type="xs:string"></xs:element>
</xs:sequence>

</xs:schema>
and here's a piece of xml which can be validated with the schema:

I've tried adding a simpleType to the XSD, but when I validate it using the W3C's online -- http://www.w3.org/2001/03/webdata/xsv -- XSV program I get errors...I was told to add a simpleType for a comments section, I've tried the following by adding onto the XSD you wrote here:

The way you declare the simpletype is incorrect. Check for examples from that tutorial you were pointed to in the other thread..
If I were you, I would also consider these things:
- Why do you need simpleType for the comment-element? Why not just declare it like this: <xs:element name="comment" type="xs:string"/> ?
- Should the comment-element perhaps be under the root element (record)?
- Do you really wan't to use sequences? Check what you can do for example with <xs:choise> and <xs:all> tags.. and also check the use of minOccurs and maxOccurs attributes with those elements.

Sub DisplayCustomer(ByVal position As Integer)
Dim node As XmlNode = xmlDoc.SelectSingleNode("/Customers/Customer[" & position & "]")
This is VB.NET. What would be the C# equivlient?
I have this so far, pero no function.
void DisplayCustomer(int position)
{
XmlNode node=xmlDoc.SelectSingleNode(@"/Customers/Customer[position]");
/\ |_ E X E GG
|
|
|
|
|
Ok, I have fixed it. For the C# version, all you have to do is replace the "&'s" with "+'s" like this...
BEFORE:
void DisplayCustomer(int position)
{
XmlNode node = xmlDoc.SelectSingleNode("/Customers/Customer[position]");
AFTER:
void DisplayCustomer(int position)
{
XmlNode node = xmlDoc.SelectSingleNode("/Customers/Customer[" + position + "]");
I guess I kinda ignored the fact that the SelectSingleNode parameter is a string. Oh well.
/\ |_ E X E GG

I heard that it's easier to learn the XML Schemas than it is for the XML DTD, how true is this? Also, does anyone know ehere to find a very detailed tutorial for XS but speaks to the beginner?

i have the following tags in an .xsl
<?xml version="1.0" encoding="iso-8859-1"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:msxsl="urn:schemas-microsoft-com:xslt"
xmlns:js="http://www.netlink.com/schemas">
<xsl:output version="1.0" method="html"
encoding="iso-8859-1" omit-xml-declaration="yes"/>
but when i apply the .xsl to the .xml it generates the following META tag
<META http-equiv="Content-Type" content="text/html; charset=UTF-16">
which causes some problems because of the UTF-16, specifically it doesn't display correctly the accents in a site that is in spanish
any idea why is this tag being inserted even if i have a meta tag in my .xsl
thanks in advance

I have an XSD schema file that defines data structures for a legacy EDI system (still in use.) As we're moving more and more apps to .Net, and our customers are doing the same, we're adding WebService support for processing transactions currently handled by the EDI systems.
The edi definitions XSD file will be used by applications other than the new WebService, and will provide cross-compatibility for a variety of applications that communicate back and forth by passing this data around.
The XSD that defines valid service requests and responses for the WebService is dependent on the edi definitions in the edi.xsd file. To provide the customer an opportunity to pre-validate transaction requests prior to sending, I have a WebMethod that returns the WebService's XSD file. The problem lies in the fact that the WebService's XSD imports the edi.xsd.
Actually, this isn't much of a problem. It's a simple matter to provide a fully-qualified URL for the schemaLocation in the <xsd:import> element. The real problem lies in the fact that both schema definitions change with some regularity. And at any one time we may have up to four separate versions of each file (dev, test, staging/cust test, production).
My concern lies in this last problem. I'm concerned that if we hard-code the URL of the development edi.xsd schema into the development WebService schema, that someone may forget to change it as the WebService moves up the deployment ladder. It would be a VBT for us to have a production schema that is importing a development schema dependency. One experimental change to the development edi schema could cause the WebService to cease functioning.
I know there have to be other shops that are providing dynamic XSD's with imports to their clients/customers. What's a good tried-and-true method of ensuring that each level of WebService XSD imports the correct version of the edi.xsd?
Is there any way to combine the two schemas on-the-fly, so that the client only has one schema definition to look at, instead of having to find the imported schema?
Alternatively, would it be possible for me to return an XmlSchema object that properly refers to the correct dependency schema(s)? I've looked into the XmlResolver, which may work for this, but I've had no success figuring out how to attach one to an XmlSchema.
I've also considered returning an XmlSchemaCollection containing both schemas, but there's a bug in the framework that prevents an XmlSchemaCollection from being a return type on a WebMethod. Whenever I try to do this, I get an InvalidOperationException.
Any solutions or suggestions are appreciated.
Thanks

Hi !
I'm trying to compile expatpp in order to use the same functions as in the testexpatpp2.cpp example file. But it happens that there's some trouble with the OOfile library.
Here is the command line i'm using to compile :
g++ testexpatpp2.cpp ../src_pp/expatpp.o -o testexpatpp2 -I/home/.../XML/src/expatpp/expat/xmlparse/ -I/home/.../XML/src/expatpp/src_pp/ -I/home/.../XML/src/expatpp/oofileBits/ -lexpat
Just to say, the other examples testexpat.c and testexpatpp.cpp are working so the problem is coming from -I/home/.../XML/src/expatpp/oofileBits/ -lexpat

As far as i understand what's going on it seems that the config has not been well done, if not it won't try to redefine bool like this !
So my question is : what can i do to make it work !
Help !
Merci de votre attention

I have a very simple XML file:
<?xml version="1.0" encoding="utf-8"?>
<Transactions>
<Transaction BoothNum='1' Date='5/22/2004' Time='5:18:02 PM' Quarters='5'/>
<Transaction BoothNum='1' Date='5/22/2004' Time='5:18:25 PM' Quarters='10'/>
</Transactions>
(wierd, the editor is converting the T's to lower case.)
And some very simple code:
XmlDocument doc=new XmlDocument();
doc.Load("transactions.xml");
try
{
XmlNode n=doc.SelectSingleNode("sum(/Transactions/Transaction[@BoothNum='1']/@Quarters)");
...
And I get that stupid error. Why doesn't sum work?
If I call doc.SelectNodes("/Transactions/Transaction[@BoothNum='1']/@Quarters"
) I get two Nodes back!
Thanks!
