TextAbsorber - How to parse \r\n?

Aspose.PDF Product Family
1
Hello,
I'm using Aspose.Pdf (version 9.3.0.0) to read a PDF file and examine its contents. But get the text through TextAbsorber method, it is unclear when it is a single line break '\r\n' or when it is a breach of several lines '\r\n\r\n' or worse .... when is a line break '\r\n' due to a column that has reached its limit of characters (in this case I should replace with space).

Is there a pattern I can replace these '\r\n' ?

Following sample text:
"Tribunal Regional \r\n\r\n\r\n\r\n Severino Rodrigues dos Santos\r\n\r\n Presidente \r\n\r\n João Leite de Arruda Alencar \r\n Vice-Presidente \r\n\r\n Avenida da Paz, 2076 \r\n\r\n Centro\r\n Maceió/AL \r\n \r\n CEP: 57020440 \r\n \r\n Telefone(s) : (82) 2121 8299 \r\n\r\n\r\n\r\n \r\n Secretaria Judiciária \r\n

Hi Marco,


Thanks for contacting support.

As per my understanding, you are trying to extract the text from PDF file and facing an issue or manually determining the line break inside extracted contents and placing/adding \n\r characters. Please share some further details regarding your requirement, the source PDF file and code snippet which you are using, so that we can test the scenario at our end. We are sorry for this inconvenience.

Hello,
I just need to differentiate a break (end of line) header line break line when the text reaches the edge of the page and the text starts on the next page (it is NOT the end of the line really). And both have the same control line break '\r\n\r\n' !!

Code:
string dataDir = Path.GetFullPath(@"C:\Projetos\CriarWord\Word\Word\");

Aspose.Pdf.Document pdfDocument = new Aspose.Pdf.Document(dataDir + "TRT_MColumn.pdf");
TextAbsorber textAbsorber = new TextAbsorber();
pdfDocument.Pages.Accept(textAbsorber);
string linha = "";
for (int page = 1; page <= pdfDocument.Pages.Count; page++)
{
pdfDocument.Pages[page].Accept(textAbsorber);
linha = textAbsorber.Text;
//....
}

Hi Marco,


Thanks for sharing the details.

As per my understanding, you are trying to find the point/location where page break occurs and page contents are displayed on subsequent page. You do not need to find/identify the line break. Can you please acknowledge that I have properly understood your requirement, so we may reply accordingly.

Do not,

I'm trying to identify two situations (for PDF with 2 columns or more):

1) The deliberate line break (like a small header row) + ENTER
2) A line that goes to the limit and generates an "ENTER" to proceed to the next line.

For the "2" position I shall replace this "enter" for "space" is only a continuation of the text on another line (not a real newline!)

How to differentiate the "ENTER" on items 1 and 2?

Thanks

Hi Marco,


Thanks for sharing the details. Let me rephrase what I have understood.

You need to identify the points/position where an Enter was added/pressed to create a line break and identify the point where contents of line are moved to subsequent line, when contents are reached the right edge of page (automatic word wrapping).
8
Exact.

Because the "automatic word wrapping"'ll need to change "space" to join the line.

And ENTER "pressed" no this need.

How is it possible to distinguish these two situations for me to change the correct line breaks?

Att,
