Some trouble with the new RegExp engine in Writer. Forum discussion: http://forum.openoffice.org/en/forum/viewtopic.php?f=7&t=58510
On Writer, when you do a S&R you can use regular expressions or set a format (Format button on "More options") but it seems you cannot do both at the same time https://issues.apache.org/ooo/show_bug.cgi?id=121482 This is a quite strange bug. Suppose you have a text with parts on italic, and you need to search for those parts and "tag" them. On previous versions it was possible to search for .* selecting "Italics" and replace by <i>&</i>, for example, but if you try this on 3.4.1 or the latests builds from trunk the "match" goes beyond the formatted text up to the end of the paragraph. If you left the Search box empty but set the format, the search find only the italic text... but then you cannot use the Replace box (you obtain <i>&</i>, not the original text, tagged). If you use [:alpha:]* \w* ... the S&R operation will work... but only with single words: no spaces, no punctuation signs, and for the first one no numbers will be selected (which is correct, but that do not solve the original problem)... so the last test is to use [:any:]* expression that will fail in the same way .* fails: selecting from the first italic character up to the end of the paragraph. I do not remember this problem on 3.4.0. Regards Ricardo
