I have a process that reads an XML file. It uses the XMLTextReader class to do this as it is supposed to be a fast, forward only XML parser/reader. Works just great with a 1 megabyte test file but comes to a complete halt when working on a 12 meg file in the live system. Are there any solutions to this other than writing my own XML rea...
Consider the following code snippet private void ProcessFile(string fullPath) { XmlTextReader rdr = new XmlTextReader("file:\\\\" + fullPath); while (rdr.Read()) { //Do something } return; } Now, this functions fine when passed a path like: "C:\Work Files\Technical Information\Dummy.xml" But throws an error w...
Ok another WPF question, well I guess this is just general .NET. I have an xml document retreived from a URL. I want to get multiple values out of the document (weather data, location, some other strings). When I use the XmlTextReader I can call my method to pull the values out. The first time I pass the method to search for the xml no...
I am struggling with a sensible logic loop for stripping out nodes from an XML file too large to use with XPath supporting .NET classes. I am attempting to replace the single line of code I had (that called SelectNodes with an XPath query string) with code that does the same but uses an XmTextReader. I have to go several levels down as...
This is probably a really simple thing, but I haven't been able to find it, and I'm probably just searching for the wrong thing... XmlTextReader --> Does it lock the file you're reading? I'm using reader.Read() and that's about it. ...
I have retrieved some XML from an API (at least I think so, the server response is 'OK') however I am putting the response stream into an XmlTextReader, how do I output this XML as a string? ...
Greetings all. I'm getting an asp.net error "Root element is missing" when I load the results of a REST request into an XmlDocument. The same REST request looks fine and returns valid results when I execute it using the Firefox addon "RESTTEST". But the error shows up in the C#.net code-behind. Does anyone know what might cause this?...
I am creating a method in a DLL that is going to be dropped into a web application. The web application has a folder with a XML file in it: /files/myfile.xml My dll has to reference that DLL, but I can't hard code the path to the file obviously. How can I reference that file and load a XmlTextReader with that file? ...
Hi, using xmltextreader, how would I load a hashtable. XML: <base><user name="john">2342343</user><user name="mark">239099393</user></base> This was asked before but it was using some funky linq that I am not fully comfortable with just yet. ...
I have logged in to the site with my webbrowser and whenever I try to call WebClient myWebClient = new WebClient(); string str = myWebClient.DownloadString("http://localhost/myxml.aspx"); Response.Write(str.ToString()); Or XmlTextReader reader = new XmlTextReader(url); while (reader.Read()) { Response.Write(reader.ReadOuterXml()); ...
I have a website that needs to pull information from two diffferent XML data sources. Originally I only need to get the data from one source so I was building a URL in the backend that went and retrieved the data from the XML site and then parsed and rendered it in the front end of the website. Now I have to use a 2nd data source and me...
How do you convert XmlReader to XmlTextReader? Code Snippet: XmlTextReader reader = XmlTextReader.Create(pomfile.FullName); Here's the Build error I got: Cannot implicitly convert type 'System.Xml.XmlReader' to 'System.Xml.XmlTextReader'. An explicit conversion exists(are you missing a cast?). pomfile is of type FileInfo ...
I'm saving 2-dimensional coordinates on an XML file with a structure similar to: <?xml version="1.0" encoding="utf-8" ?> <grid> <coordinate time="78"> <initial>540:672</initial> <final>540:672</final> </coordinate> </grid> I can open the XML file and read it via the XmlTextReader, but how do I loop through the coordinates specifica...
I'm parsing some XML in C#. I'm getting it from a database, and so converting it to a MemoryStream before reading it with an XmlTextReader. The problem is that I get this error: Name cannot begin with the ' ' character, hexadecimal value 0x20. Line 1, position 3. Following is my XML and my code for reading it (it's coming out of the data...
Hi all, I have multiple XML files that I need to parse. Problem is that I only need some data in the last couple of lines. I currently use XMLTextReader and reader.ReadToFollowing("DATANEEDED"); but it is still too slow. Does anyone know if I can 'tail' an XML file and read from there? (taking into account the tail would not be a ...
I am reading an XML file using an XMLTextReader. Is there a way to tell the difference between a start tag (like <tag>) and a self-terminating tag (like <tag />) ...
I receive an XML file with encoding "ISO-8859-1" (Latin-1) Within the file (among other tags) I have <OtherText>Example "content" And ─</OtherText> Now for some reason when I load this into XMLTextReader and do a "XmlReader.Value" to return the value, it returns: "content" And ─ This then, when confronted with a datab...
I've traced slugishness in my application to the bit of code that's being timed below. I knew that this would be a slow point but each request is taking an average of 1 second. The bit of xml that I'm after is always in the first tag so I don't think it's the download times that are getting me. Stopwatch stopwatch = new Stopwatch(); Xml...
Is there something that is similar to XmlTextReader in terms of performance, but using JSON instead? I have the choice between parsing data in XML or parsing the same data in JSON. I'd like to use JSON because I figure I could save a bit of bandwidth but I'd like to keep the performance of XmlTextReader. In other words, how do I stream...
