I'm trying to read from an onix file and save the information onto a mysql database.
I'm able to read titles, country code, isbn and other fields but for some strange reason I cant get short description.
The short description field is embed in html text and when I try to read from it without any alternations it doesnt work and if i tried to save it as a string does the same.
On the database I created a field in the table shortdescription varchar(70) and i also, at first thought it was the amount its allowed to stored "varchar(70)" if I increase it, doesn't help!
This is part of an onix feed I'm trying to read
01 reader-friendly introduction to one of the most influential areas of economics today. Covering all core areas of the subject, the book requires no advanced mathematics and is full of examples, exercises, and problems drawn from the fields of economics, management, marketing, political science, and public policy, among others. It is an ideal first textbook for students coming to behavioral economics from a wide range of disciplines, and would also appeal to the general reader looking for a thorough and readable introduction to the subject. Available to lecturers: access to an Instructor's Manual at www.palgrave.com/economics/angner, containing a sample syllabus, instructor guide, sample handouts and examinations, and PowerPoint slides.]]>
I tried using this code below, the same theory worked for getting the isbn etc.:
Function HandleTagName(name as String) as XName Select Case name Case "d104", "text" If ShortName Then Return "d104" Else Return "text" End If end select end function dim xmlDoc as XDocument dim xr as XmlTextReader = new XmlTextReader(Server.MapPath(ThisBook.FromFile)) xr.Namespaces = false dim document as XmlDocument = new XmlDocument() document.Load(xr) xr.close() if not document("ONIXmessage") is Nothing then Dim attrColl as XmlAttributeCollection = document("ONIXmessage").Attributes attrColl.RemoveAll() end if xmlDoc = XDocument.Parse(document.OuterXML) Dim Products As IEnumerable(Of XElement) if xmlDoc.DocumentType is Nothing then ShortName = True else if instr(xmlDoc.DocumentType.ToString(), "/short") then ShortName = True end if end if Products = from product in xmlDoc.Root.Descendants(HandleTagName("Product")) For Each ThisOtherText In product.Elements(HandleTagName("OtherText")) If ThisOtherText.Element(HandleTagName("TextTypeCode")) = "02" Then If ThisBook.shortDescription = "" Then ' if you say ' dim xxx as string = "test" ' ThisBook.shortDescription = xxx ThisBook.shortDescription = ThisOtherText.Element(HandleTagName("Text")) End if End If Next
I'm not sure if its something i'm not doing right in the code or is it something to do with how i declared shortdescription on the database
Oh, is all you want to do read a .xml file into a VB.NET string?
Imports System.IO ... Dim xmlfilereader as streamreader = new streamreader("locationofxmlfile.xml") dim xmlfilestring as string = xmlfilereader.read()
xmlfilestring is now a string containing your XML file. Is that all you wanted?
