How to find text when SearchPatternText is split with CRLF

[alvesmarc]

Hello,

Spire.PDF is probably the solution to our needs, however we have a problem right now.

Our goal is to find text pattern on a PDF document and to replace it by some other values.
When dealing with a PDF wherein the text pattern to seek is on a single line, everything is ok. But if the same text pattern is split on multiple line on the PDF, for instance because of the layout of a cell tab (too small to contain the full text so PDF use CRLF to display the text), in this case it's not working anymore.

Find attached a screenshot of the PDF not ok.

I'm using this code :

Code: Select all

page.FindText("ThisIsTheTextThatWeWouldLikeToMatch", TextFindParameter.WholeWord).Finds

I tried with Regex mode and also CrossLine one, still not ok.

It seems that the FindText can only consider one single line...

Can you please tell us if there is a possibility to deal with this case ?

Thanks a lot.

Hello,

Thanks for your inquiry!

I created a PDF with the table according to you describe, and I did cannot find the word "ThisIsTheTextThatWeWouldLikeToMatch" with our Spire.PDF as you mentioned.

After further investigate, I found that even in Adobe or Google Chrome, they cannot find the word which break into lines since we all cannot judge it is a word or a sentence when it breaks into lines. Sorry that we cannot support deal with this. Hope you can understand.

Hi Marcia,

First of all, thanks a lot for your quick reply and the complete test you made.

In fact, I tried either to do a search with Adobe Reader and it works correctly on my side. Please find it on my screenshot.

Please consider one important point, the text ThisIsTheTextThatWeWouldLikeToMatch is inserted in a whole unique work in the PDF, it's simply the PDF generation that have a split it with a carriage return because of the size of the cell tab... But the word is a single word, not separated by any space char...

Do you still think that Spire.PDF cannot handle it ?

Thanks again !

Hello,

Thanks for your feedback!

To help us better investigate this issue, could you please provide us with the PDF document you are testing with, and the Adobe version you are using? Since in my simulated document, I cannot find the word you point out. Here I also attached my PDF, and the Adobe version I am using. Thanks in advance.

Sure thing.

Attached my test PDF doc and this is the version of my Acrobat Reader :

Also, I cannot find the text on your document, I really think that is because you text is using an explicit CRLF...

thx
