How can i do that using xml reader. I google and see traversing for a single node but not in loop. any inputs? 回答1: You can use LINQtoXML to get the

问题 This question already has answers here : Problem reading files greater than 1GB with XMLReader (6 answers) Closed 5 years ago . I've written an application that parses large XML files in PHP using XMLReader. Generally, the application works great, EXCEPT when I attempt to read a file that's larger than 2gb. (I haven't figured out exactly where the cut-off is; it works flawlessly on a 500mb file, but fails on the next largest file I have - 2.5gb). Specifically, if my code looks like this:

问题 I am trying to construct a custom Error Message for unsuccessful XML validation using the callback validation event.

I trying to build the path of the current node failing in the validation by getting the parent nodes of the current node Given below is the code snippet XmlReaderSettings xrs =

问题 I have to read a file content Base64 string in an element of XML that is returned from an API. My problem is this string can be very long, depending on file size. At first, I used XmlDocument to read XML. Now I use XmlReader to avoid System.OutOfMemoryException when XML is too large. But I when I read the string, receive a System.OutOfMemoryException too. The string is too long, I guess. using (XmlReader reader = Response.ResponseXmlXmlReader) { bool found = false; //Read result while (reader

问题 Actually i'd like to know if XmlMtomReader reads mime binary parts from the input stream directly? Or does it store them internally before i call ReadContentAsBase64() method? 回答1: As I recall (and it's been a while...), XmlMtomReader does the minimal amount of internal storage required, depending on the order in which the MIME parts appear in the input stream. (The MTOM standard allows them to appear in any order). So if your input stream is, for example: Binary part 1 Then the main XML part

问题 I currently have to fix an existing application to use something other than the DOM interface of libxml2 because it turns out it gets passed XML files so large that they can't be loaded into memory. I have rewritten the data loading from iterating over the DOM tree to using xmlTextReader for the most part now without too much problems. ( I use xmlNewTextReaderFilename to open a local file.) It turns out however, that the subtree where the large data resides has to be read not in-order, but I

问题 I've got strange behaviour of the XmlReader. When using it for validation Xml against Xsd everythink works fine and how I expect. But when I try validate a Xsd file against another Xsd, it throws no validation exception. For better explenation of my use case: I have an application where an user can upload a Xml file like data input. The user must upload a xsd file for already uploaded xml file and after that, the Xml file is validated against the Xsd file already uploaded. But in the case

问题 I'm trying to deserialize a xml response from a Rest service. I'm implementing IXmlSerializable because the xml is rather specific and I do custom serializing. The response contains illegal xml characters but as I have no way to modify the xml I'll have to deal with them. The solution seems simple : when creating my XmlReader I feed it XmlSetting with ChecCharacters set to false : XmlReaderSettings settings = new XmlReaderSettings(); settings.CheckCharacters = false; using (var reader =
