How to select text between 2 tags

[LPCR]

Hi,
i seacrh how to create a TextSelection with all text between 2 tags.
I can easily find the tags :

Code: Select all

                Regex regEx = new Regex("\\?my_tag\\?");
                TextSelection[] selections = doc.FindAllPattern(regEx);
                if (selections!=null && selections.Count()==2)
                {
                    //select text ....

                    //delete selection
                }

Hi LPCR,

Thanks for you inquiry.
You could find the TextSelection you want to change, and then replace it with new text. Please see the code as reference which I have tested below.

Code: Select all

            string s1 = "begin";
            string s2 = "end";
            Regex regEx = new Regex("(?<=(" + s1 + "))[.\\s\\S]*?(?=(" + s2 + "))");
            //Get the selections between "begin" and "end"
            TextSelection[] selections = doc.FindAllPattern(regEx);
            if (selections != null)
            {     
                TextRange range = selections[0].GetAsOneRange();
                //Replace with new text
                range.Text = "this is replace content";             
            }

            doc.SaveToFile("replace.docx", FileFormat.Docx2013);
            System.Diagnostics.Process.Start("replace.docx");

Hope it will help. If i misunderstanding, please contact us and give more information.

Thanks for your response,
but in my case the 2 tags are not in the same line.
they can be in different pages. So change the regex is not enougth

Hello LPCR,

After an investigation, I generate the code below for your reference.

Code: Select all

            Document doc = new Document();
            doc.LoadFromFile("insertText.docx");

            string s1 = "begin";
            string s2 = "end";
            StringBuilder sb = new StringBuilder();
            TextSelection[] selections1 = doc.FindAllString(s1, true, true);
            TextSelection[] selections2 = doc.FindAllString(s2, true, true);
           
            TextRange tag1Range = selections1[0].GetAsOneRange();
            TextRange tag2Range = selections2[0].GetAsOneRange();

            ParagraphCollection pc = doc.Sections[0].Paragraphs;

            //get the paragraph index of 2 tags
            int pIndexBegin = pc.IndexOf(tag1Range.OwnerParagraph);
            int pIndexEnd = pc.IndexOf(tag2Range.OwnerParagraph);
           
            //get the follow text of tag1 in the paragraph where tag1 in
            DocumentObjectCollection tag1objs = pc[pIndexBegin].ChildObjects;
            TextRange range1 = selections1[0].GetAsOneRange();
            int childIndex1 = tag1objs.IndexOf(range1);
            for (int i = childIndex1 + 1; i < tag1objs.Count; i++)
            {
                TextRange bRange = tag1objs[i] as TextRange;
                string str = bRange.Text;

                sb.Append(str);

            }

            //get the text of paragraphs between 2 tags
            for (int i = pIndexBegin + 1; i < pIndexEnd; i++) {
                sb.Append(pc[i].Text);
            }

            //get the pre text of tag2 in the paragraph where tag2 in
            DocumentObjectCollection tag2objs = pc[pIndexEnd].ChildObjects;
            TextRange range2 = selections2[0].GetAsOneRange();
            int childIndex2 = tag2objs.IndexOf(range2);
            for (int i = 0; i < childIndex2; i++)
            {
                TextRange bRange = tag2objs[i] as TextRange;
                if (bRange != null) {
                    string str = bRange.Text;
                    sb.Append(str);
                    if (str == s2)
                    {
                        break;
                    }
                }

            }

Hello Simon,

I have the same problem as LPCR, but I'm not sure I understand the reference code you posted. The question was for a TextSelection, but it looks like this code puts all the 'selected' tekst in a stringbuilder.

Is there a way to get all this in a TextSelection so I can delete or modify the whole selection? And is it not possible for the FindPattern results to span several lines or even pages (if not, are there any plans to support this in the future)?
Regex is able to return results spanning multiple lines, so I'd expect FindPattern to behave the same.

Regards,
Saskia Brand

Dear Brand,

Thanks for your inquiry.
Please use the method FindPatternInLine to find the text spanning several paragraphs or even pages.

Code: Select all

            Regex regEx = new Regex(@"(?<=start)[.\s\S]*(?=end)");
            TextSelection[] selections = doc.FindPatternInLine(regEx);

If there is any question, please let me know.
