You don't mention if there can be one or more example nodes within each catalog node.
This code works if there are many catalog's with one example node.
="1.0"="utf-8"
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl"
>
<xsl:output method="text" indent="no"/>
<xsl:template match="catalog">
<xsl:value-of select="example"/>
</xsl:template>
</xsl:stylesheet>
And this code works if there are many catalog nodes and many example nodes.
="1.0"="utf-8"
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl"
>
<xsl:output method="text" indent="no"/>
<xsl:template match="catalog">
<xsl:apply-templates select="example" />
</xsl:template>
<xsl:template match="example">
<xsl:value-of select="node()"/>
</xsl:template>
</xsl:stylesheet>
XSLT is recursive by nature, so no need for the loop.
If you want text output, I don't understand the HTML tags in your example code.

So, should I post it here instead of quick answer section?

Hello,
I'd like to serialize an Objekt with XmlSerializer. The Objekt is a kind of treeview with lots of public properties like this:
public object Instance;
Currently I have different kind of classes stored in the Instance objects, all inheriting from the same base class. If I want to serialize these, I need to tell the XmlSerializer in an XmlAttributeOverrides object about the different Instance object classes. I collect this information dynamically before starting the XmlSerializer.
Setting a breakpoint just before that I can check the Overrides object which looks like this:
- Overrides {System.Xml.Serialization.XmlAttributeOverrides} System.Xml.Serialization.XmlAttributeOverrides
- Non-Public members
- types Count = 5 System.Collections.Hashtable
- [{CTrModules.MDataSaveXML}] {System.Collections.Hashtable}
+ Key {Name = "MDataSaveXML" FullName = "CTrModules.MDataSaveXML"} object {System.RuntimeType}
- Value Count = 1 object {System.Collections.Hashtable}
+ ["Instance"] {System.Xml.Serialization.XmlAttributes}
+ Raw View
- [{CTrModules.QSM_Var_Dict}] {System.Collections.Hashtable}
+ Key {Name = "QSM_Var_Dict" FullName = "CTrModules.QSM_Var_Dict"} object {System.RuntimeType}
- Value Count = 1 object {System.Collections.Hashtable}
+ ["Instance"] {System.Xml.Serialization.XmlAttributes}
+ Raw View
- [{System.String}] {System.Collections.Hashtable}
+ Key {Name = "String" FullName = "System.String"} object {System.RuntimeType}
- Value Count = 1 object {System.Collections.Hashtable}
+ ["Instance"] {System.Xml.Serialization.XmlAttributes}
+ Raw View
- [{CTrModules.MHandleException}] {System.Collections.Hashtable}
+ Key {Name = "MHandleException" FullName = "CTrModules.MHandleException"} object {System.RuntimeType}
- Value Count = 1 object {System.Collections.Hashtable}
+ ["Instance"] {System.Xml.Serialization.XmlAttributes}
+ Raw View
- [{FFV_Cockpit.InternalExcHandler}] {System.Collections.Hashtable}
+ Key {Name = "InternalExcHandler" FullName = "FFV_Cockpit.InternalExcHandler"} object {System.RuntimeType}
- Value Count = 1 object {System.Collections.Hashtable}
+ ["Instance"] {System.Xml.Serialization.XmlAttributes}
Now here's my problem: I get a InvalidOperationException: "The type CTrModules.MDataSaveXML was not expected."
Looking through the Overrides above, CTrModules.MDataSaveXML was handed over to the serializer along with all other classes. All other classes can be serialized, but not this one. All classes have the Serializable attribute and are inheriting the same base class.
I'm at a loss here. Why is CTrModules.MDataSaveXML not expected?
I'm using C# in Visual Studio Espress 2013 for Windows Desktop, the target framework is .NET Framework 4.
TIA,
Christian

Hi Bernhard,
Bernhard Hiller wrote: Did you add the [XmlInclude(typeof(CTrModules.MDataSaveXML))]
attribute to the base class
I don't really want to go with that option, because then I have to remember to add such an include for any class I derive from the base class.
But I tried it just for test purposes: I get the same problem.
The option I chose to use is this one:
Bernhard Hiller wrote: or pass an array of types to the constructor of the serializer?
I wrote a method to gather all types in an array and I pass this array to the serializer.
I set a breakpoint at the call of the serializer and inspected this array:
- Overrides {System.Xml.Serialization.XmlAttributeOverrides} System.Xml.Serialization.XmlAttributeOverrides
- Non-Public members
- types Count = 5 System.Collections.Hashtable
- [{CTrModules.MDataSaveXML}] {System.Collections.Hashtable}
+ Key {Name = "MDataSaveXML" FullName = "CTrModules.MDataSaveXML"} object {System.RuntimeType}
- Value Count = 1 object {System.Collections.Hashtable}
+ ["Instance"] {System.Xml.Serialization.XmlAttributes}
+ Raw View
- [{CTrModules.QSM_Var_Dict}] {System.Collections.Hashtable}
+ Key {Name = "QSM_Var_Dict" FullName = "CTrModules.QSM_Var_Dict"} object {System.RuntimeType}
- Value Count = 1 object {System.Collections.Hashtable}
+ ["Instance"] {System.Xml.Serialization.XmlAttributes}
+ Raw View
- [{System.String}] {System.Collections.Hashtable}
+ Key {Name = "String" FullName = "System.String"} object {System.RuntimeType}
- Value Count = 1 object {System.Collections.Hashtable}
+ ["Instance"] {System.Xml.Serialization.XmlAttributes}
+ Raw View
- [{CTrModules.MHandleException}] {System.Collections.Hashtable}
+ Key {Name = "MHandleException" FullName = "CTrModules.MHandleException"} object {System.RuntimeType}
- Value Count = 1 object {System.Collections.Hashtable}
+ ["Instance"] {System.Xml.Serialization.XmlAttributes}
+ Raw View
- [{FFV_Cockpit.InternalExcHandler}] {System.Collections.Hashtable}
+ Key {Name = "InternalExcHandler" FullName = "FFV_Cockpit.InternalExcHandler"} object {System.RuntimeType}
- Value Count = 1 object {System.Collections.Hashtable}
+ ["Instance"] {System.Xml.Serialization.XmlAttributes}
It contains all classes, including CTrModules.MDataSaveXML. All other classes can be serialized, but not this one.
CU,
Christian

Hello, I have a xml file and try to select nodes with a xpath query based on multiple attribute values, but can't get it to work. please tell me the correct xpath.
here's part of the xml:
<AppInt ID="91" Type="Get_Rcp_Rel_Content">
<Tags>
<tag ID="300" ROLE="REQTRG" PLCID="PLC008" DB="113" ADDRESS="36" LENGTH="1" DATATYPE="INT" />
<tag ID="301" ROLE="RSPTRG" PLCID="PLC008" DB="113" ADDRESS="38" LENGTH="1" DATATYPE="INT" />
<tag ID="302" ROLE="modeID" PLCID="PLC008" DB="113" ADDRESS="40" LENGTH="1" DATATYPE="INT" />
<tag ID="303" ROLE="jobID" PLCID="PLC008" DB="113" ADDRESS="42" LENGTH="1" DATATYPE="INT" />
<tag ID="304" ROLE="RcpRelID" PLCID="PLC008" DB="113" ADDRESS="44" LENGTH="1" DATATYPE="INT" />
<tag ID="305" ROLE="Enable" PLCID="PLC008" DB="113" ADDRESS="46" LENGTH="1" BIT="0" DATATYPE="BOOL" />
<tag ID="306" ROLE="FillingTime" PLCID="PLC008" DB="113" ADDRESS="48" LENGTH="1" DATATYPE="LONG" />
<tag ID="307" ROLE="FillingRPM" PLCID="PLC008" DB="113" ADDRESS="52" LENGTH="1" DATATYPE="REAL" />
</Tags>
<Setpoints>
<Setpoint JobID="1002" ModeID ="1" Name="Enable" Value="True"/>
<Setpoint JobID="1002" ModeID ="1" Name="FillingTime" Value="5500"/>
<Setpoint JobID="1002" ModeID ="1" Name="FillingRPM" Value="53.2"/>
</Setpoints>
</AppInt>
and here's my xpath query:
//AppInt [@ID="91"]/Setpoints [Setpoint/@JobID="1002" and Setpoint/@ModeID="1"]/@Name
|
|
|
|
|
Which nodes are you trying to select?
|
|
|
|
|
You asked the right question: I was trying to select the setpoint nodes, so i must remove the @Name.
|
|
|
|
|
Try this:
//AppInt[@ID="91"]/Setpoints/Setpoint[@JobID="1002" and @ModeID="1"]/@Name

Hello!
I have no possibility to use following-sibling axis.
How can I get the same functionality in XPath without using axes? Is it real?
Thanks in advance.

Guys, give me your thoughts on how you validate your xml at runtime. I recently fell into a drawn-out debug session where I couldn't see the problem with my xml file. I opened it in c#, read it, and checked for various attributes and what have you, adopting plan B that if I don't find an attribute I'll assume a default value.
The problem was I had an attribute called Recursion but I inadvertently spelt it Recursive, not the same thing! 
I know I could validate the xml with an xsd file which sounds great in principal but is that the preferred way to validate your xml or do you do it the "safer" (word used very loosely) way by keeping all the literal names in your code and then issue warnings if things don't pass muster?
The xsd file itself could for any number of reasons be subject to an incorrect edit. I'd like to know which way you do things to ensure that when it comes to the usage, your xml is as clean to use as you can make it. Ideas?
If there is one thing more dangerous than getting between a bear and her cubs it's getting between my wife and her chocolate.

|
|

I would say an xsd file is the way to do it. You could possibly verify your xsd file with a CRC32 value.

First time I have to do this. I know, where have I been the last 10 years...
Given a structure:
struct {
int A;
int B;
another_struct aStruct;
float fValue;
} my_binary_data;
What is the best practice way to dump this in Xml format as well as read it? We're using rapidXml on this project, and what I've seen in existing code is line after line of sprint operations to format and then insert each tagged value into the Xml file. Pretty much the same thing trying to read the Xml back in.
My concern is that some of my structures are going to be changing day by day, and keeping the conversion code up to data is going to be tedious.
Anyone have a better way to do this, or is this just the nature of the beast?

Since XML is text based you have very little choice. Perhaps you need to investigate whether XML is the optimum solution to your problem.
Use the best guess

Appreciate the feedback. As in many projects, some things are being decided by other people. I'm just trying to get a handle on what to expect. If it has to be done this way, it has to be done this way  .
Past projects have exchanged data between devices using binary. This has disadvantages - byte swapping issues, messages tied to data structures, etc.

I am receiving xml from an external web service that I am consuming in a C# application.
The xsd has this line:
<xs:element type="xs:byte" name="contract_term"/>
Most of the files received have this element set to a value but I have just come across one that has it empty:
<contract_term/>
Is this valid, or should I raise it with the web service producer?
|
|
|
|
|
It's syntactically valid XML; what's the problem?
Use the best guess
|
|
|
|
|
I would expect that a value of 0 to 255 would be present for an element marked as byte and it should never be empty. It caused the .NET XmlSerializer to throw an exception when deserializing the data.
I have done a work around by deserializing to a string instead and having an additional property that returns the result parameter of byte.TryParse on the string, but it's a bit messy.
|
|
|
|
|
If you think it's wrong then you should talk to the provider of the XML data.
Use the best guess
|
|
|
|
|
I have raised it with them, but not being very knowledgeable in the finer points of XML/XSD I wasn't sure about it's validity.
|
|
|
|
|
Try making the byte a nullable. As far as I know byte is generally a value type which means it can't be null.
e.g. in c#
byte? elementName
|
|
|
|
|
Yes, you are correct about byte being a value type (in .NET anyway). I haven't tried using nullable so don't know how the XmlSerializer will respond to it - could be interesting!
