xmlreader

问题 I'm currently rewriting a PHP class that tried to split an XML file into smaller chunks to use XMLReader and XMLWriter instead of the current basic filesystem and regex approach. However, I can't figure out how to get the version, encoding and standalone flags from the XML preamble. The start of my test XML file looks like this: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE fakedoctype SYSTEM "fake_doc_type.dtd"> <!-- This is a comment, it's here to try and get the parser to break in some

问题 I have an XML file that is approximately 12mb which has about 16000 product's. I need to process it into a database; however, at about 6000 rows it dies with a 500 error.

During the parsing, I have this encoding error: Input is not proper UTF-8, indicate encoding ! Bytes: 0xA0 0x32 0x36 0x30 I would like to know if they are a way to skip records with bad characters.
