SMIL or XHTML (such as NavDoc) with UTF8 BOM fail to XML-parse

[danielweck]

To check if there is a BOM:

sed $'1 s/\xEF\xBB\xBF/BOM/' < "/PATH/TO/FILE" | head -c10 && echo ""

[danielweck]

To list all the culprit files in the current folder:

find . -type f \( -name "*.html" -or -name "*.xhtml" -or -name "*.js" -or -name "*.css" -or -name "*.smil" \) -print0 | xargs -0 -I % sh -c "echo ''; echo %; sed $'1 s/\xEF\xBB\xBF.*/zzzzzzzzzzzzzz BOM/' < % | head -n1 ; echo ''"

Or to filter out only the BOMs:

find . -type f \( -name "*.html" -or -name "*.xhtml" -or -name "*.js" -or -name "*.css" -or -name "*.smil" \) -print0 | xargs -0 -I % sh -c "echo ''; sed $'1 s/\xEF\xBB\xBF.*/BOM /' < % | head -c4 ; echo %;" | grep "BOM"
