C# - XElement.ToString() Causes System.OutOfMemoryException?
Nov 25, 2010
I have an XElement object that contains about 120MB of data. The XML consists of approx 6000 elements of about 20kb each.
I am trying to call XElement.ToString() as I need to return the OuterXml in a webservice.
I am getting a System.OutOfMemoryException.
System.OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was thrown:
at System.String.GetStringForStringBuilder(String value, Int32 startIndex, Int32 length, Int32 capacity)
at System.Text.StringBuilder.GetNewString(String currentString, Int32 requiredLength)
at System.Text.StringBuilder.Append(Char[] value, Int32 startIndex, Int32 charCount)
at System.IO.StringWriter.Write(Char[] buffer, Int32 index, Int32 count)
at System.Xml.XmlEncodedRawTextWriter.FlushBuffer()
at System.Xml.XmlEncodedRawTextWriter.WriteAttributeTextBlock(Char* pSrc, Char* pSrcEnd)
at System.Xml.XmlEncodedRawTextWriter.WriteString(String text)
at System.Xml.XmlEncodedRawTextWriterIndent.WriteString(String text)
at System.Xml.XmlWellFormedWriter.WriteString(String text)
at System.Xml.XmlWriter.WriteAttributeString(String prefix, String localName, String ns, String value)
at System.Xml.Linq.ElementWriter.WriteStartElement(XElement e)
at System.Xml.Linq.ElementWriter.WriteElement(XElement e)
at System.Xml.Linq.XElement.WriteTo(XmlWriter writer)
at System.Xml.Linq.XNode.GetXmlString(SaveOptions o)
at System.Xml.Linq.XNode.ToString()
I have the same data in an XmlDocument and can call XmlDocument.OuterXml without a problem. I can also call XElement.Save() to save the XML to a file without a problem.

I have a website that I have run for years running a custom built CMS. It has had no problems ever. I decided to create a demo (temporary url) of the CMS using the exact same website. Only people I give access to would be able to login and change it, so it basically is not in use for the most part.
I tried this demo site the past few days, and I noticed that I kept getting System.OutOfMemoryException errors. I would wait for an hour or so, then it would work. Next day, same thing.
What could explain this? 2 exact same websites....one that is used all the time (no memory issues), and one that is hardly ever used (memory issues). Doesn't really make sense to me.

I have an XML file I need to parse, but only for the text, not the HTML. Here's an example of a node:
<highlights><![CDATA[<ul style="color:#000000;font-size:small;font-family:verdana,geneva,sans-serif"><li>Classy & elegant purse hooks</li><li>Choose from various styles<br></li><li>Stable and reliable</li><li>Makes a great gift! </li></ul> ]]></highlights>
As you can see, the CDATA has HTML code in it, so when I do element.Value I also get the tags. Is there any simple way to get just the text?
