C# 正则表达式多重匹配

Question

I have this regex to extract paragraphs that are outside of a table

((?<=<\/w:tbl>)<w:p [^>]*>.*?<\/w:p>(?=<w:tbl>)|(?<=<\/w:tbl>)<w:p [^>]*>.*?<\/w:p>(?=<w:sectPr.*>))

The problem is that it reads all paragraphs as if they are one paragraph (from the first opening tag until the last closing tag without the intermediate paragraphs). Below is an example of the text. In this case it match one instead of 3

</w:tr></w:tbl><w:p w:rsidR="00F24C60" w:rsidRDefault="00F24C60" w:rsidP="009D46A1"><w:pPr><w:spacing w:before="240" w:after="240"/></w:pPr><w:r><w:t></w:t></w:r></w:p><w:p w:rsidR="00F24C60" w:rsidRDefault="00F24C60" w:rsidP="009D46A1"><w:pPr><w:spacing w:before="240" w:after="240"/></w:pPr><w:r><w:t></w:t></w:r></w:p><w:p w:rsidR="00346D4D" w:rsidRPr="00AC7B53" w:rsidRDefault="00F24C60" w:rsidP="009D46A1"><w:pPr><w:spacing w:before="240" w:after="240"/></w:pPr><w:r><w:t></w:t></w:r></w:p><w:tbl><w:tblPr>

Any help to make it match each paragraph alone (3 paragraphs)?

Thanks.

Answer 1

I think, you can't, because you want to create groups inside another tags, but regex don't know about structures it just looking string from begin to end, assume string: eabcabce if need all abc groups I can do next (abc) , however I can't tell that I want all abc groups between e .

You can use some xml parser.

You can try two regexes for this particular case:

1. Get content of tbl tag with your regex
2. Get groups from tbl content with this regex (<w:p [^>]*>.*?<\/w:p>)

some links:

1. why not to parse html with regex (I think your xml is close to html:)) RegEx match open tags except XHTML self-contained tags
