OpenXml: Worksheet Child Elements change in ordering results in a corrupt file

阅读更多关于 OpenXml: Worksheet Child Elements change in ordering results in a corrupt file

问题 I am trying to use openxml to produce automated excel files. One problem I am facing is to accomodate my object model with open xml object model for excel.

Word 2007 saves its documents in .docx format which is really a zip file with a bunch of stuff in it including an xml file with the document. I want to be able to take a .docx file and drop it into a folder in my asp.net web app and have the code open the .docx file and render the (xml part of the) document as a web page. I've been searching the web for more information on this but so far haven't found much. My questions are: Would you (a) use XSLT to transform the XML to HTML, or (b) use xml manipulation libraries in .net (such as XDocument and XElement in 3.5) to convert to HTML or (c) other

What are some libraries that extend OpenXML (or add a kind of abstraction layer to OpenXML) similar to ClosedXML? I'm looking for a commercial or freeware tool with at least 1.0 version.

"Excel stores dates as a float value... the integer part being the number of days since 1/1/1900 (or 1/1/1904 depending on which calendar is being used), the fractional part being the

问题 On September 28, 2009 the Apache POI project released version 3.5 which officially supports the OOXML formats introduced in Office 2007, like DOCX and XLSX. Please provide a code sample for extracting a DOCX file's content in plain text, ignoring any styles or formatting.
