XML on the Server
XML files are plain text files just like HTML files.
XML can easily be stored and generated by a standard web server.
Storing XML Files on the Server
XML files can be stored on an Internet server exactly the same way as
HTML files.
Start Windows Notepad and write the following lines:
<?xml version="1.0" encoding="ISO-8859-1"?>
<note>
<from>Jani</from>
<to>Tove</to>
<message>Remember me this weekend</message>
</note>
|
Save the file on your web server with a proper
name like "note.xml".
Generating XML with ASP
XML can be generated on a server without any installed XML software.
To generate an XML response from the server - simply write the
following code and save it as an ASP file on the web server:
<%
response.ContentType="text/xml"
response.Write("<?xml version='1.0' encoding='ISO-8859-1'?>")
response.Write("<note>")
response.Write("<from>Jani</from>")
response.Write("<to>Tove</to>")
response.Write("<message>Remember me this weekend</message>")
response.Write("</note>")
%>
|
Note that the content type of the response must be set to "text/xml".
See how the ASP file will be returned from
the server.
If you want to study ASP, you will find our ASP tutorial on our
homepage.
Generating XML with PHP
To generate an XML response from the server using PHP, use
following code:
<?php
header("Content-type: text/xml");
echo "<?xml version='1.0' encoding='ISO-8859-1'?>";
echo "<note>";
echo "<from>Jani</from>";
echo "<to>Tove</to>";
echo "<message>Remember me this weekend</message>";
echo "</note>";
?>
|
Note that the content type of the response header must be set to "text/xml".
See how the PHP file will be returned from
the server.
If you want to study PHP, you will find our PHP tutorial on our
homepage.
Generating XML From a Database
XML can be generated from a database without any installed XML software.
To generate an XML database response from the server, simply write the
following code and save it as an ASP file on the web server:
<%
response.ContentType = "text/xml"
set conn=Server.CreateObject("ADODB.Connection")
conn.provider="Microsoft.Jet.OLEDB.4.0;"
conn.open server.mappath("/db/database.mdb")
sql="select fname,lname from tblGuestBook"
set rs=Conn.Execute(sql)
response.write("<?xml version='1.0' encoding='ISO-8859-1'?>")
response.write("<guestbook>")
while (not rs.EOF)
response.write("<guest>")
response.write("<fname>" & rs("fname") & "</fname>")
response.write("<lname>" & rs("lname") & "</lname>")
response.write("</guest>")
rs.MoveNext()
wend
rs.close()
conn.close()
response.write("</guestbook>")
%>
|
See the real life database output
from the ASP file above.
The example above uses ASP with ADO.
If you want to study ASP and ADO, you will find the tutorials on our
homepage.
Transforming XML with XSLT on the Server
This ASP transforms an XML file to XHTML on the
server:
<%
'Load XML
set xml = Server.CreateObject("Microsoft.XMLDOM")
xml.async = false
xml.load(Server.MapPath("simple.xml"))
'Load XSL
set xsl = Server.CreateObject("Microsoft.XMLDOM")
xsl.async = false
xsl.load(Server.MapPath("simple.xsl"))
'Transform file
Response.Write(xml.transformNode(xsl))
%>
|
Example explained
- The first block of code creates an instance of the Microsoft XML parser
(XMLDOM), and loads the XML file into memory.
- The second block of code creates
another instance of the parser and loads the XSL file into memory.
- The last
line of code transforms the XML document using the XSL document, and sends the
result as XHTML to your browser. Nice!
See how it works.
Saving XML To a File Using ASP
This ASP example creates a simple XML document and saves it on
the server:
<%
text="<note>"
text=text & "<to>Tove</to>"
text=text & "<from>Jani</from>"
text=text & "<heading>Reminder</heading>"
text=text & "<body>Don't forget me this weekend!</body>"
text=text & "</note>"
set xmlDoc=Server.CreateObject("Microsoft.XMLDOM")
xmlDoc.async="false"
xmlDoc.loadXML(text)
xmlDoc.Save("test.xml")
%>

WAPT
is a load, stress and performance testing tool for websites and web-based applications.
In contrast to "800-pound gorilla" load testing tools, it is designed to minimize the learning
curve and give you an ability to create a heavy load from a regular workstation.
WAPT is able to generate up to 3000 simultaneously acting virtual users using standard hardware configuration.
Virtual users in each profile are fully customizable. Basic and NTLM authentication methods are supported.
Graphs and reports are shown in real-time at different levels of detail, thus helping to manage the testing process.
