Problem with regular expressions
I'm having some trouble writing a regular expression to delete page headers in the conversion options. The page header I'm trying to delete basically looks like
Code:
<p class="calibre1"> Title</p><p class="calibre1"> Page 42 of 230</p> Code:
Title</p><p class="calibre1">\nPage [0-9]* of [0-9]* Seeing as I've never used regular expressions before and just skimmed over the Calibre user manual to piece it together, I'm sure there's something I'm missing, but I cant figure out what it is. What I can figure out is that I somehow don't get how to match a newline. Could anyone help? Last edited by Manichean; 01-12-2010 at 07:07 AM. |

Unfortunately, that doesn't work. Same problem, it just gets confused about the linebreak.
I thought about maybe passing a flag that the string it should match is on multiple lines, but I don't know how to do this and currently, I'm too busy to figure it out. I'll post again once I find a solution. |

I messed with this a little. I don't know exactly what you are looking for but here is what I have. This should only match on a number followed by a </p> followed by an end of the line.
Search: of \d+</p>$ Replace <\p> So this will find the last line of your three lines with the page number followed by the <\p> at the end of a line. Then replace only the <\p>. It looks like this before: >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> sides, and above the jacket collar behind, uncombed. Both beards were short and scant. <p class="calibre1"> Title</p><p class="calibre1"> Page 42 of 230</p> The man from the east wore a standard straight sword, the plastic <<<<<<<<<<<<<<<<<<<<<<<<<<<<< And now after: >>>>>>>>>>>>>>>>>>>>>>>>>>>>> <p class="calibre1"> Title</p><p class="calibre1"> Page 42 </p> <<<<<<<<<<<<<<<<<<<<<<<<<<<< This just removes the "of XXX" page numbering part. Is that what you were after? Archon |

Did you try this:
Code:
Title</p><p class="calibre1">\s*Page\s*[0-9]+\s*of\s*[0-9]+ Edit: Note if non-breaking spaces are your problem you can create a character class to include them. Instead of \s*, use this: [\su00a0]* Last edited by ldolse; 02-02-2011 at 11:43 PM. |

You people do realize that this thread is about a year old? I solved that issue quite some time ago. (The solution was me stopping to be stupid, by the way.)

I thought it was odd, that you, who done the regex faq/guide couldn't manage it.
I did look at date, and thought orig post was December. |

BTW what was your solution (besides stopping being stupid as you say)? Maybe we could all learn from your experience. Archon |

The problem was that I didn't use the regex wizard to test it, basically. I tried to use Notepad++, which doesn't allow for multiline regex matching. (I only found that out while writing the guide, actually.) The reason I did that was that I felt Notepad++ would be faster than Calibre, and I didn't fully understand the wizard. Also, had I known about character classes, especially \s, I might have found a solution sooner.
