i have a xml file on a server that look for example like this one:
<breakfast_menu>
<food>
<name>Belgian Waffles</name>
<price>$5.95</price>
<description>two of our famous Belgian Waffles with plenty of real maple syrup</description>
<calories>650</calories>
</food>
<food>
<name>Strawberry Belgian Waffles</name>
<price>$7.95</price>
<description>light Belgian waffles covered with strawberries and whipped cream</description>
<calories>900</calories>
</food>
</breakfast_menu>
i need xml parser that will parse it and enter each one of them to a class that for examle will called food(and have 4 parameters : name,price,.....).
and finally to create an array of the classes that he create.there is built xml parser that do it?
Here are some sources on the topic:
Navigating XML from Objective-C
How do I parse an NSString containing XML in Objective-C?
Objective C: Parsing an XML file
Parsing XML in Cocoa

For learning to parse xml, look at the links Brandon provided. Your requirement to build an array of classes from xml is something you'll need to create yourself.
A suggestion I have for you is instead of creating classes, just put the data into a NSMutableArray. The array will contain NSDictionary objects for food sub-items.

I have a simple question.
Let's say I have a pList that contains 1 string and 2 arrays. Each Array has 100 elements.
Is there a way to load only 1 of the 2 arrays without loading the entire pList into memory ?
Thanks a lot.
The plist is a XML format text file. So, you can parse the file by XML parser with SAX manner. The sample code XMLPerformance includes a good example about libxml which parses data with SAX manner.
I want to compare two XML documents to find and show where is the difference
like diff utility in XCode.
I can retrieve and parse xml code using NSXMLParser in basic level,
and can tell 'they are not exactly same'
but I don't know how to tell 'where and which'.
Is there any open-source based library for this?
Thanks in advance.
Try following link

also try this
I am using libxml for parsing the xml. I have referred the XMLPerformance example by apple.
Following is the part of xml document which is causing a problem as it contain the " " string. i cannot just replace this " " with any other string is i am getting data in didReceiveData delegate method and i am parsing that data.
Is there any solution to resolve this issue which is coming because of special character?

To make sure your XML is well format, you can test you XML first with any online XML validator and then later you should parse that.
is it possible to use the OPEN XML SDK and generate an xml file that contains some metadata of a particular docx file?
details: i have a docx file, from which i want to extract some metadata(using open xml) and display them as xml file and later use Jquery to present them in a more readable form.
You can use the SDK to extract info from the various properties parts which may be present in the docx (for example, the core properties part, which included dublin core type info).
You can extract it in its native XML form:
<cp:coreProperties
xmlns:cp="http://schemas.openxmlformats.org/package/2006/metadata/core- properties"
xmlns:dc="http://purl.org/dc/elements/1.1/" .. >
<dc:creator>Joe</dc:creator>
<cp:lastModifiedBy>Joe</cp:lastModifiedBy>
<cp:revision>1</cp:revision>
<dcterms:created xsi:type="dcterms:W3CDTF">2010-11-10T00:32:00Z</dcterms:created>
<dcterms:modified xsi:type="dcterms:W3CDTF">2010-11-10T00:33:00Z</dcterms:modified>
</cp:coreProperties>
or, in some other XML dialect of your own choosing.
I know question was posted a long time ago, but first result of google search sent me here. So if there are others looking for a solution to this, there is a snippet on MSDN website https://msdn.microsoft.com/en-us/library/office/cc489219.aspx
short answer is... using XmlTextWritter, and it applies to Office 2013 afaik:
// Add the CoreFilePropertiesPart part in the new word processing document.
var coreFilePropPart = wordDoc.AddCoreFilePropertiesPart();
using (XmlTextWriter writer = new XmlTextWriter(coreFilePropPart.GetStream(FileMode.Create), System.Text.Encoding.UTF8))
{
writer.WriteRaw("<?xml version=\"1.0\" encoding=\"UTF-8\"?>\r\n<cp:coreProperties xmlns:cp=\"http://schemas.openxmlformats.org/package/2006/metadata/core-properties\"></cp:coreProperties>");
writer.Flush();
}
I am new to XML parsing. I am parsing the following XML. There are tutorials for if XML has unique attributes but this XML has repeating attributes.
<?xml version="1.0" encoding="utf-8"?>
<start>
<Period periodType="A" fYear="2005" endCalYear="2005" endMonth="3">
<ConsEstimate type="High">
<ConsValue dateType="CURR">-8.9919</ConsValue>
</ConsEstimate>
<ConsEstimate type="Low">
<ConsValue dateType="CURR">-13.1581</ConsValue>
</ConsEstimate>
</Period>
< Period periodType="A" fYear="2006" endCalYear="2006" endMonth="3">
<ConsEstimate type="High">
<ConsValue dateType="CURR">-100.000</ConsValue>
</ConsEstimate>
<ConsEstimate type="Low">
<ConsValue dateType="CURR">-13.1581</ConsValue>
</ConsEstimate>
</Period>
</start>
I need to fetch the low and high values based on the years 2005 and 2006.
I agree with SB's comment, if you wan't to handle xml-datastructurse, you should know at least the basic stuff.
A good tutorial i can reccomend is ww3 schools XML Tutorial
once you did that, you should know that there are several ways to parse xml files. For flatfiles i recommend to use the TBXML Library, it is really fast and easy to handle within your code.
