xmlreader

I am using the code below to read a ~2.5Gb Xml file as fast as I can (thanks to MemoryMappedFile). However, I am getting the following exception: " '.', hexadecimal value 0x00, is an invalid character. Line 9778, position 73249406. ". I beleive it is due to some encoding problem. How do I make sure that the MemoryMappedViewStream reads the file using UTF-8? static void Main(string[] args) { using (var file = MemoryMappedFile.CreateFromFile(@"d:\temp\temp.xml", FileMode.Open, "MyMemMapFile")) { using (MemoryMappedViewStream stream = file.CreateViewStream()) { Read(stream); } } } static void

I've used HtmlAgilityPack in the past to parse HTML in .Net but I don't like the fact that it only uses a DOM model. On large documents and/or those with heavy levels of nesting it is possible to hit stack overflow or out of memory exceptions. Also in general a DOM based parsing model uses significantly more memory than a streaming based approach, typically because the process that wants to consume the HTML may only need a few elements to be available at a time. Does anyone know of a decent HTML parser for .Net that allows you to parse HTML in a manner similar to the XmlReader class? i.e. in a

In my Silverlight application I'm using mostly XmlReader but I'm playing with idea to replace XmlReader implementation with LINQ to XML. What are pros and cons between LINQ to XML and XmlReader in Silverlight? PROs of Linq to XML Query XML documents with the same LINQ syntax your used to Uses the same X objects that you're used to working with (XElement, etc.) PROs of using XmlReader Finer grain control over the query syntax (XPath rather than LINQ) ...personally, I switched to LINQ to XML when it was first introduced and never looked back. Haven't noticed any significant performance

So I am using the filestream inside xmlreader using (XmlReader reader = XmlReader.Create(new FileStream(archivePath, FileMode.Open), readerSettings)) { reader.close() } However, the file feed into the xmlreader still in the lock state after the using scope, weird, I thougt the xmlreader is going to close the filestream for me, is it not? Thanks for help. Have you tried this? using(var stream = new FileStream(archivePath, FileMode.Open)) using(var reader = XmlReader.Create(stream, readerSettings)) { } I couldn't find anything in the documentation that explicitly stated that the XmlReader would

Here's the XML string. <?xml version="1.0" encoding="utf-16"?> <questionresponses> <question id="dd7e3bce-57ee-497a-afe8-e3d8d25e2671"> <text>Question 1?</text> <response>abcdefg</response> <correctresponse>123</correctresponse> </question> <question id="efc43b1d-048f-4ba9-9cc0-1cc09a7eeaf2"> <text>Question 2?</text> <response>12345678</response> <correctresponse>123</correctresponse> </question> </questionresponses> So how could I get value of <response> element by given question Id? Say, if I give id value = "dd7e3bce-57ee-497a-afe8-e3d8d25e2671", I'd like to have string value abcdefg

I have the following sitemap XML which contains a list of URLs to be submitted for search engines. I took this example code from another SO answer. // Init XMLWriter $writer = new XMLWriter(); $writer->openURI(APPLICATION_PATH . '/sitemap.xml'); // document head $writer->startDocument('1.0', 'UTF-8'); $writer->setIndent(4); $writer->startElement('urlset'); $writer->writeAttribute('xmlns', 'http://www.sitemaps.org/schemas/sitemap/0.9'); // Write something // this will write: <url><loc>some url here; SO not allowed me</loc></url> $writer->startElement('url'); $writer->writeElement('loc', 'some
