I'm looking for a fast and efficient way to retreive 2 strings from multiple xml files.
The files them selves aren't that big only 50kb to 100kb and the number of files can range from none to 100. I've included a sample of a very small xml file i'll be using. All xml files will be the same format and there's only 2 things i need to know from all files namely:
<Company>test bv.</Company>
<Ship>sss testing</Ship>
i want to store these strings in a struct/class since i cannot use Tuple in .net 3.5 (or am i mistaking?)
so the question: what is the most efficient way to do this? using Xdocument? using xmlReader? or something else?

I would just use LINQ to XML in the simplest possible way:
var query = from file in files
let doc = XDocument.Load(file)
from customer in doc.Descendants("Customer")
select new {
Company = (string) customer.Element("Company"),
Ship = (string) customer.Element("Ship")
};
I'd expect that to be pretty quick already - but you should work out what your exact performance requirements are, then test them. (You almost certainly don't need "the most efficient" way - you need a sufficiently efficient way, whilst keeping the code readable.)
Note that if you want the values to be propagated out of the current method, you should create your own class to represent the company/ship pair.

I have this template from a bank that is used to make payments on bank account transfers.
See xml below. I have included the sample data that has to be entered when sending the file to the bank.

The file is quite long as has to be in the format given. The black letters represent the details to be passed to the xml. To test if I understood what data goes where I filled it manually and sent to bank for testing. That is all good now.
I have a SAP addon program that captures details from a form and generates a list. Each payment must follow this structure.
Looking at the below:
<Nm>CART LIMITED</Nm>
<Id>
<OrgId>
<Othr>
<Id>S001234/PJones</Id>
<SchmeNm>
<Cd>CUST</Cd>
</SchmeNm>
</Othr>
</OrgId>
</Id>
Is creating a class with all properties according to the template the best way to create the xml needed.
How do I stagger the
<Id>
<OrgId>
<Othr>
as in the case above?
Also the <CtrlSum>667896.00</CtrlSum> is found in the group header and payment info tags. How do I deal with this?
For what i see, the problem is you have a addon in SAP to specify multiple payments methods, but in the XML template given from the bank you don't the structure for multiple payments, so you need to get this information to know how can you work with it.
when you have this information you can use a better XML template with VS or another tool to generate the correct class to work with the XML
hi following XML is my input XML

<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>

<author Seq="0">
<Inital>A.El</Inital>

</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.
I am writing some C# code with the intention of periodically downloading an XML file, comparing the resulting XML with a previously downloaded version of XML (to detect changes), and then "actioning" the changes (via appropriate CRUD statements) by updating database records which reflect the entities in the XML.
I need some help with the "comparing the resulting XML with a previously downloaded version to detect changes" part of the requirements.
So... considering the following two XML documents which have minor differences...

Summary of Differences
Vehicle id="2575124" is not present in the original. This represents a "create".
Vehicle id="2574074" is not present in the new. This represents a "delete".
Vehicle id="2648665" (which is present in both original and new) has a different <Colour> (WHITE -> BRILLIANT WHITE). This represents an "update".
Vehicle id="2648665" also has new <Image> nodes in the new. This represents a "create" (as images will be 1:M with the vehicle in the database).
I have looked at XMLDiff to generate a DiffGram with add/change/remove instructions but I can't see a way to make it generate a DiffGram that represent the changes I've summarised, e.g. it sees changes 1 and 2 as an "change" - <xd:change match="#id">2648665</xd:change> - rather than the absence and addition of a vehicle.
Is there a way to do this with XMLDiff?
Or, is there a "better" way to achieve the result I'm looking for?
I've found that LINQ can do a pretty good job of parsing the XML for differences, e.g...
XDocument xNewVehicle = new XDocument(new XElement("UsedStock",
from newVehicle in newXml.Descendants("Vehicle")
join oldVehicle in oldXml.Descendants("Vehicle")
on newVehicle.Attributes("id").First().Value equals oldVehicle.Attributes("id").First().Value into oldVehicles
where !oldVehicles.Any() // where the vehicle exists in new but not in old
|| newVehicle.ToString() != oldVehicles.First().ToString() // where the new vehicle is not the same as the old vehicle
select newVehicle));
I have an xml file

I want to select book id. I tried using this
#"/BookLib/Book/Title[contains(translate(text(),'ABCDEFGHIJKLMNOPQRSTUVWXYZ','abcdefghijklmnopqrstuvwxyz'),'" + searchText + "')]/#Id";
in XPathExpression
how can i retrieve 'id' using xpath in c#
Since #Id is below Book, not Id, you have to move back up to get it:
#"/BookLib/Book/Title[contains(translate(.,'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz'),'"
+ searchText.ToLower() + "')]/../#Id";
or do the comparison without moving down to Title in the first place:
#"/BookLib/Book[contains(translate(Title,'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz'),'"
+ searchText.ToLower() + "')]/#Id";
I personally prefer the latter because it seems a bit cleaner.
First you can use fn:lower-case() which is better than fn:translate as it use Unicode mapping to change the case. So it will work with accent like É->é, À->à, etc.
Then you can simplify by using XPath axes.
So, to get the #Id, you can use the following XPath (adapt to C#) :
#"//Book/Title[contains(lower-case(./text()),'" + searchText.ToLower() + "' )]/#Id";
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.
