Hi,
*Solution :-*
I askd this problem long before.....
Here I give u steps I followed and failed...
1. I downloaded "PDFBox" DLLs and exposed all the necessary methods. I
failed because it was giving some security exceptions. I configured trust
level to full and made some settings like AllowPartialTrustedCallers etc.
But all in vain. Exceptions still remained.
2. I tried "iTextSharp" DLLs. I got rid of security exceptions but cropped
up with another error "Resource or File not found". I chkd the path as well
but still.... System.IO exceptions..... :(
3. I tried "PDFToText.exe" . Following code was used for this :-
=======================================
string strFile = Server.MapPath(FileUpload1.PostedFile.FileName);
System.Diagnostics.Process p = new System.Diagnostics.Process();
p.StartInfo.Arguments = " -raw -htmlmeta" + " " + strFile + " " +
"E:\\PDFCont\\output.htm"; ;
p.StartInfo.FileName = Page.MapPath("pdftotext.exe");
p.StartInfo.UseShellExecute = false;
p.StartInfo.CreateNoWindow = false;
p.StartInfo.RedirectStandardOutput = false;
p.Start();
p.WaitForExit();
System.Threading.Thread.Sleep(3000);
===============================
Still stuck with System.IO exceptions.
*Working Code :-*
Finally I tried "ASPPDFLib" DLLs. It worked for me like anything..... :) . I
had to extract text from the PDF file and to generate XML. Here you are...
with working solution..... :)
===========================================
using ASPPDFLib;
protected void btnRead_Click(object sender, EventArgs e)
{
string strExtractTxt = getPDFText(@"E:\PDFCont\Tabular.pdf");
StringReader sr = new System.IO.StringReader(GenerateXML(strExtractTxt));
DataSet dsInfo = new DataSet();
dsInfo.ReadXml(sr);
}
public string getPDFText(string pstrFilePath)
{
IPdfManager objPdf = new PdfManager();
// Open a PDF file for text extraction
IPdfDocument objDoc = objPdf.OpenDocument(pstrFilePath, Missing.Value);
String strText = "";
foreach (IPdfPage objPage in objDoc.Pages)
{
strText += objPage.ExtractText(Missing.Value);
}
strText = Server.HtmlEncode(strText);
return strText.Trim();
}
public string GenerateXML(string pstrExtractTxt)
{
string[] strSplitArr = pstrExtractTxt.Split(' ');
ArrayList strSplitArrCopy = new ArrayList();
string strXML = "<Information>";
for (int x = 0; x < strSplitArr.Length; x++)
{
if (strSplitArr[x] != string.Empty) { strSplitArrCopy.Add(strSplitArr[x]); }
}
int i = 0;
for (int x = 3; x < strSplitArrCopy.Count; x++)
{
if (i == 0) strXML += "<Person>";
strXML += "<" + strSplitArrCopy[i] + ">" + strSplitArrCopy[x] + "</" +
strSplitArrCopy[i] + ">";
if (i == 2) { strXML += "</Person>"; i = 0; }
else i += 1;
}
strXML += "</Information>";
return strXML;
}
===============================================
Hope this solution may help those guys who are looking for PDF text
extraction.
