How does one check the validity of an XML file to show where the xml error occurs?
Firefox can do it, but I’d like to do it in linux/windows command line.
eg. I’ve got a large-ish (90MB) XML file from Excel, saved in XML Spreadsheet 2003 format. It contains various invalid data, so that Firefox spits out messages like this:
Line Number 790402, Column 65:
<Cell ss:StyleID="s18"><Data ss:Type="String">Here's some data I?Bnternational</Data></Cell>
Firefox is quite slow at parsing my XML(presumably because it’s keeping it all in memory ready to render into a nice navigable tree). I’m not bothered about validation against an XSD, just want to know if the XML is well-formed.
There’s a linux command called xmllint that is good for this. It’s very fast, handles honking great files without barfing, and gives useful validation error messages.
