Regular Expressions to XML

[Jo M]

Hello,

Does anyone of you know any tool that would convert regular expressions
to XML compatible form?

I mean tool that would convert e.g. & to & etc.

I have written an ASP.NET C# application that uses regular expressions
stored in XML file but a tool that would convert Regexp to XML compatible
form would be nice,

Cheers!

It's not a tool, per se, but the framework has built-in escaping:
System.Text.StringBuilder sb = new System.Text.StringBuilder();

new System.Xml.XmlTextWriter(new
System.IO.StringWriter(sb)).WriteString("&");

You can use XmlWriter and its WriteString method to escape a string e.g.

XmlWriterSettings writerSettings = new XmlWriterSettings();
writerSettings.ConformanceLevel = ConformanceLevel.Fragment;
using (XmlWriter xmlWriter = XmlWriter.Create(Console.Out,
writerSettings)) {
xmlWriter.WriteString("Kibo & Xibo");
}

outputs "Kibo & Xibo".

Hello again!

I wrote a small Windows App that converts
characters to XML.

Code below:
StringBuilder sb = new StringBuilder();

new System.Xml.XmlTextWriter(new

StringWriter(sb)).WriteString(this.txtBoxFrom.Text );

this.txtBoxTo.Text = sb.ToString();

If I give & to txtBoxFrom field it writes &amp; to txtBoxTo field

but when givin " it writes " not &quot; that it should write.

Can anyone point what is still missing?

Cheers!

Hmm, that's a weird one. I had to go in and read some docs on it a bit, but
the problem is that the quote is only escaped when in the context of an
attribute:
WriteString does the following

a.. The characters &, <, and are replaced with &amp;, &lt;, and &gt;,
respectively.

b.. Character values in the range 0x-0x1F (excluding white space
characters 0x9, 0xA, and 0xD) are replaced with numeric character entities
(� through &#0x1F).

c.. If WriteString is called in the context of an attribute value, double
and single quotes are replaced with &quot; and &apos; respectively.

You'd need to do a WriteAttribute to get the write in context of an
attribute to tell the writer that it is writing between two existing
quotation marks and hence needs escaping.
