C validating filename

12 Nov

Here's how: If using the 'header' function for the downloading of files, especially if you're passing the filename as a variable, remember to surround the filename with double quotes, otherwise you'll have problems in Firefox as soon as there's a space in the filename.

So instead of typing: If you don't do this then when the user clicks on the link for a file named "Example file with spaces.txt", then Firefox's Save As dialog box will give it the name "Example", and it will have no extension.

Libxml2 also provide a SAX based API, but that version was designed upon one of the early expat version of SAX, SAX is also not formally defined for C.

SAX basically work by registering callbacks which are called directly by the parser as it progresses through the document streams.

lxml also provides support for ISO-Schematron, based on the pure-XSLT skeleton implementation of Schematron: There is also basic support for The parser in lxml can do on-the-fly validation of a document against a DTD or an XML schema.

The DTD is retrieved automatically based on the DOCTYPE of the parsed document.

The problem is that this programming model is relatively complex, not well standardized, cannot provide validation directly, makes entity, namespace and base processing relatively hard.

The Xml Text Reader API from C# provides a far simpler programming model.

All three provide identical APIs in lxml, represented by validator classes with the obvious names.

This document describes the use of the Xml Text Reader streaming API added to libxml2 in version 2.5.0 .

This API is closely modeled after the Xml Text Reader and Xml Reader classes of the C# language.

When you receive a signed document, you may want to validate its signature(s) to verify the signer and the signed content.

Depending on how you have configured your application, validation may occur automatically.
