I'm trying to do very simple operations on a .cxml file. As you know it's basically an .xml file. This is a sample file I created to test the application:
<?xml version="1.0" encoding="utf-8"?>
<Collection xmlns:p="http://schemas.microsoft.com/livelabs/pivot/collection/2009" SchemaVersion="1.0" Name="Actresses" xmlns="http://schemas.microsoft.com/collection/metadata/2009">
<FacetCategories>
<FacetCategory Name="Nationality" Type="LongString" p:IsFilterVisible="true" p:IsWordWheelVisible="true" p:IsMetaDataVisible="true" />
</FacetCategories>
<!-- Other entries-->
<Items ImgBase="Actresses_files\go144bwo.0ao.xml" HrefBase="http://www.imdb.com/name/">
<Item Id="2" Img="#2" Name="Anna Karina" Href="nm0439344/">
<Description> She is a nice girl</Description>
<Facets>
<Facet Name="Nationality">
<LongString Value="Danish" />
</Facet>
</Facets>
</Item>
</Items>
<!-- Other entries-->
</Collection>
I can't get any functioning simple code like:
XDocument document = XDocument.Parse(e.Result);
foreach (XElement x in document.Descendants("Item"))
{
...
}
The test on a generic xml is working. The cxml file is correctly loaded in document.
While watching the expression:
document.Descendants("Item"), results
the answer is:
Empty "Enumeration yielded no results" string
Any hint on what can be the error? I've also add a quick look to get Descendants of Facet, Facets, etc., but there are no results in the enumeration. This obviously doesn't happen with a generic xml file I used for testing. It's a problem I have with .cxml.
Basically your XML defines a default namespace with the xmlns="http://schemas.microsoft.com/collection/metadata/2009" attribute:
That means you need to fully qualify your Descendants query e.g.:
XDocument document = XDocument.Parse(e.Result);
foreach (XElement x in document.Descendants("{http://schemas.microsoft.com/collection/metadata/2009}Item"))
{
...
}
If you remove the default namespace from the XML your code actually works as-is, but that is not the aim of the exercise.
See Metadata.CXML project under http://github.com/Zoomicon/Metadata.CXML sourcecode for LINQ-based parsing of CXML files.
Also see ClipFlair.Metadata project at http://github.com/Zoomicon/ClipFlair.Metadata for parsing one's CXML custom facets too
BTW, at http://ClipFlair.codeplex.com can checkout the ClipFlair.Gallery project for how to author ASP.net web-based forms to edit metadata fragments (parts of CXML files) and merge them together in a single one (that you then convert periodically to DeepZoom CXML with PAuthor tool from http://pauthor.codeplex.com).
If anyone is interested in doing nesting (hierarchy) of CXML collections see

Simplified XML file I need to decode:
<?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<ns2:deliverylistResponse xmlns:ns2="http://tdriverap3.wsbeans.iseries/">
<return>
<COUNT>3</COUNT>
<DELIVERIES>
<ADD1>1300 address 1</ADD1>
<CITY>NICE CITY</CITY>
<ZIP>85705</ZIP>
</DELIVERIES>
<DELIVERIES>
<ADD1>40 S PINAL PKWY AVE</ADD1>
<CITY>FLORENCE</CITY>
<ZIP>85132</ZIP>
</DELIVERIES>
<DELIVERIES>
<ADD1>1825 EAST MAIN</ADD1>
<CITY>CHANDLER</CITY>
<ZIP>85286</ZIP>
</DELIVERIES>
<ERRORCODE/>
<RUNDATE>09/26/2018</RUNDATE>
</return>
</ns2:deliverylistResponse>
</soap:Body>
</soap:Envelope>
I am using the following to try and decode each of the individual addresses in the code.
I cannot figure out how to access them.
XElement xelement = XElement.Load(#"e:\test\X2.xml");
IEnumerable<XElement> addresses = xelement.Elements();
foreach (var address in addresses)
{
Console.WriteLine(address);
Console.WriteLine(address.Element("CITY").Value);
}
The first writeline works (it outputs the entire XML tree), the second says "System.Xml.Linq.XContainer.Element(...) returned null" - I have tried using DELIVERIES, COUNT, Body etc...
Obviously I am not telling it correctly how to traverse the structure, but I do not know how to go any further with it..
UPDATE: Thanks to some help I have figured out how to do it using Linq.
I would still like to be able to deserialize it if anybody has a pointer.
I followed several tutorials, but the multiple levels of this XML seems to be throwing me off.
I have created a class to hold the data but that is as far as my success with that path has gone.
Thank you,
Joe
Thank you Crowcoder -- this is what I wound up with, which will work.
The real XML file however does have about 60 fields so this is not as good as using a deserialize routine but I can at least move forward with the project.
XElement xelement = XElement.Load(#"e:\test\x2.xml");
IEnumerable<XElement> textSegs =
from seg in xelement.Descendants("DELIVERIES")
select seg;
foreach (var address in textSegs)
{
Console.WriteLine(address.Element("ADD1").Value);
Console.WriteLine(address.Element("CITY").Value);
Console.WriteLine(address.Element("ZIP").Value);
}
Console.ReadKey();

<titletext>PATHOGENESIS AND NEURO-PROTECTIVE AGENTS OF STROKE</titletext>

<abstract>
<cepara>ABSTRACT: Stroke remains worlds second leading cause of mortality; and globally most frequent cause of long-lasting disabilities. The ischaemic pathophysiologic cascade leading to neuronal damage consists of peri-infarct depolarization, excitotoxicity, inflammation, oxidative stress, and apoptosis. Despite plethora of experimental evidences and advancement into the development of treatments, clinical treatment of acute stroke still remains challenging. Neuro-protective agents, as novel therapeutic strategy confer neuro-protection by targeting the pathophysiologic mechanism of stroke. The aim of this review is discussion of summary of the literature on stroke pathophysiology, current preclinical research findings of neuroprotective agents in stroke and possible factors that were responsible for the failure of these agents to translate in human stroke therapies.</cepara>

from this xml i need to delete root tag alone but i need all child element
<author Seq="0">
<Inital>A.El</Inital>

<Givenname>Abdelkrim</Givenname>
</author>
how to delete root tag alone. For this i followed following code
XDocument CarXML = new XDocument();
CarXML.Add(Root);
CarXML.Descendants("root").Remove();
CarXML.Save(#"CAR.XML");
But this code delete all xml tag. How to delete root element alone. i need child element
CarXML.ReplaceNodes(CarXML.Descendants("author").FirstOrDefault());
This replaces the whole content of the XML with the first descendant named author.
What is happening \ what is the difference ?
I'm trying to return a specific node from an XML File.
XML File:
<?xml version="1.0" encoding="utf-8"?>
<JMF SenderID="InkZone-Controller" Version="1.2">
<Command ID="cmd.00695" Type="Resource">
<ResourceCMDParams ResourceName="InkZoneProfile" JobID="K_41">
<InkZoneProfile ID="r0013" Class="Parameter" Locked="false" Status="Available" PartIDKeys="SignatureName SheetName Side Separation" DescriptiveName="Schieberwerte von DI" ZoneWidth="32">
<InkZoneProfile SignatureName="SIG1">
<InkZoneProfile Locked="False" SheetName="S1">
<InkZoneProfile Side="Front" />
</InkZoneProfile>
</InkZoneProfile>
</InkZoneProfile>
</ResourceCMDParams>
</Command>
<InkZoneProfile Separation="Cyan" ZoneSettingsX="0 0,005 " />
</JMF>
Code:
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load("C:\\test\\test.xml");
XmlNode root = xmlDoc.DocumentElement;
var parent = root.SelectSingleNode("/JMF/Command/ResourceCmdParams/InkZoneProfile/InkZoneProfile/InkZoneProfile/InkZoneProfile");
XmlElement IZP = xmlDoc.CreateElement("InkZoneProfile");
IZP.SetAttribute("Separation", x.colorname);
IZP.SetAttribute("ZoneSettingsX", x.colorvalues);
xmlDoc.DocumentElement.AppendChild(IZP);
xmlDoc.Save("C:\\test\\test.xml");
The var parent returns me null. I've debugged , and root and xmlDoc have on their inner text the XML Content.
But, a test made here(made by user #har07 , on the previous question:
SelectSingleNode returns null even with namespace managing
Worked without problems.
https://dotnetfiddle.net/vJ8h9S
What is the difference between those two ? They follow the same code basically, but one works and other doesn't.
When debugging i've found that root.InnerXml has the contents loaded on itself (same as XmlDoc.InnerXml ). But InnerXml doesn't implement a method to SelectSingleNode. I believe that if i save it to a string i'll probably lose indentation and etc.
Can someone tell me what is the difference or what is wrong ? Thanks !

SetAttribute don't auto escape string for you. Therefore it make your XML file invalid.
From MSDN about XmlElement.SetAttribute
Any markup, such as syntax to be recognized as an entity reference, is treated as literal text and needs to be properly escaped by the implementation when it is written out
Find in your code all line contain SetAttribute and use SecurityElement.Escape to escape the value.
For example: Change these lines:
IZP.SetAttribute("Separation", x.colorname);
IZP.SetAttribute("ZoneSettingsX", x.colorvalues);
To:
using System.Security;
IZP.SetAttribute("Separation", SecurityElement.Escape(x.colorname));
IZP.SetAttribute("ZoneSettingsX", SecurityElement.Escape(x.colorvalues));
If an attribute have name contains any of <>"'& you also have to escape it like the value.
Note:
You have to delete current xmls you create used the old code, because it is invalid, when you load it will cause exception.
Thank you all for suggesting things and helping whenever in need.
Yesterday I was trying to develop and web app in asp.net 4.0 where I needed to parse the data from xml and save it in database. But before that I will also have to validate it.
I tried using .net provided tool xsd.exe to generate the schema file, but I dont know how will it know to mark which nodes or attributes are compulsory?
Like in my xml below items are mandatory
Root node <Market>
<Login> and its sub element
<ProductType> and its <ProductTypeID/>
The attribute DML is mandatory but should have only 3 values NONE, PUT or MODIFY
<ProductType> may or may not have <ProductItem>
If <ProductItem> is present then it should have <ProductItemID>
<ProductItem> may or may not have <Brand>
If <Brand> is present then it should have <BrandID>
Below is my xml
<?xml version="1.0" encoding="utf-8" ?>
<Market>
<Login>
<LoginId />
<Password />
</Login>
<ProductType DML="NONE">
<ProductTypeID/>
<Name/>
<Detail/>
<ProductItem DML="PUT">
<ProductItemID/>
<Name/>
<Detail/>
<Brand DML="PUT">
<BrandID/>
<Name/>
<Detail/>
</Brand>
<Brand DML="MODIFY">
<BrandID/>
<Name/>
<Detail/>
</Brand>
</ProductItem>
<ProductItem DML="MODIFY">
<ProductItemID/>
<Name/>
<Detail/>
</ProductItem>
</ProductType>
</Market>
How and where should I specify all the mandatory and optional parameters, so that my xsd is generated as per the requirement.
Thanks,
M.
xsd.exe can only try to infer, which elements/attributes are in you xml, but it cannot find out which information is mandatory. But this is a good startingpoint.
use a graphical XML_Schema_Editor to edit the genrated xsd to mark your mandatory fields. That is much easier than learning the xsd-language
I don't think XSD support nested XML. I would try to load the XML into an XmlDocument and check mandatory fields manually.
I’m after some C# code that will have the following methods that will return Xml as the result.
Search the Apple iTunes App store. If I pass it a name or partial name the function must return a list of possible search results or just one result if it is a perfect match.
Example shown below:
<App>
<AppId>321564880</AppId>

Okay the best way to create xml file and parse and manipulate them is using XDocument,XElement,etc. Because they are enumerable which means you can use LINQ on them and that will help you a lot.
For example :
XElement element = new XElement("Persons",
new XElement("Person","John",
new XAttribute("Id","1")),
new XElement("Person","Aaron",
new XAttribute("Id",2))
)
returns
<Persons>
<Person Id="1">John</Person>
<Person Id="2">Aaron</Person>
</Person>
More information : System.Xml.Linq Namespace
If you are looking for speed, then you can use XMLReader and XMLWriter but you can't find the flexibility that System.Xml.Linq provides.
You should use XPath in .NET:
http://www.aspfree.com/c/a/.NET/Working-with-XPath-The-NET-Way/
I would use XmlTextReader. It's the fastest way (though read-forward-only) - if you are maybe looking for speed. If not, XPath should do.
