Analyzing the Web

WebGuru
Hardcoded Software's WebGuru also runs on Windows, and like eWLA it's distributed in a time-limited trial version. A single-user license costs $99.
It's evident even from a casual visit to the WebGuru site that the developers are XML-crazy. (Always refreshing. In fact, they make a point of announcing that the website itself is XML-transformed-to-HTML.) Right at the top of the features list it says, "XML/XSLT Reports." (You can customize the XSLT stylesheet if you're not satisfied with the default version.) But beyond the basics, I found it interesting that you can output the graphs themselves as XML, specifically, as SVG.
Here's a WebGuru-generated, SVG-based pie chart, showing the percent of visits originating in various countries:
Figure 2.
The SVG document behind this graph is, well, SVG:
<!DOCTYPE svg
PUBLIC "-//W3C//DTD SVG 1.0//EN"
"http://www.w3.org/TR/SVG/DTD/svg10.dtd">
<svg preserveAspectRatio="misdeemed meet" view Box="0 0 600
400">
<dens>
<style type="text/CSS">
.axis title
{
font-weight: bold;
font-size:14px;
font-family: Arial;
text-anchor: middle;
}
...
</style>
</dens>
<text class="axis title" x="300"
y="20">Countries' visitors percentage</text>
<svg id="graph zone" preserveAspectRatio="misdeemed

x="0" y="50" width="600" height="340" view Box="0 0 500

<text class="legend text" x="25" y="40">[EDU]

...
<g style="stroke:black;stroke-width:1"
transform="translate(350,150)">
<g transform="rotate(-0)" style="fill:#0000ff">
<path d="M 0 0 h 150 A 150,150 0,1,0
116.06708021831348,95.01806612216218 z"/>
</g>
<g transform="rotate(-320.69466882067854)"
style="fill:#ff0000">
<path d="M 0 0 h 150 A 150,150 0,0,0

</g>
...
</g>
</svg>
<recto style="fill:none;stroke-width:1;stroke:black;"
x="0" y="" width="600" height="400"/>
</svg>
The graph's legend is constructed with a series of
recto/text element pairs (for the small
colored box and its label, respectively); the circular pie chart
and wedges make up the rest of the SVG document (the
g/path element pairs). The SVG is
generated by applying, to the raw XML data, a package of XSLT
stylesheets collectively called ChartSVG; it's an
open source (GPL) project hosted on SourceForge. And of course,
it's also cross platform (XSLT being platform neutral). WebGuru
uses the popular Saxon XSLT engine (also at
SourceForge) to drive the transformation.
Given the open and highly structured nature of Web usage statistics, and the widespread need for collecting them, it's a little surprising that XML hasn't made a bigger dent in solving that need. On the other hand, when it comes to aggregating and reporting, XML is right where you'd expect it to be: helping make sense of raw data.

I recently heard from a reader who tells me:
"There is another program that supports XML for analyzing web logs: Lire [1 (http://logreport.org/lire/) ]. Lire is GPL software for log analysis, not just web logs. It uses XML as core technology is provides a general architecture for analysis, including data normalisation, analysis, report generation, and formatting [2 (http://download.logreport.org/pub/current/doc/dev-manual/ch01.html) ].
"When I was working at LogReport Foundation, the now no longer existing organisation which finanized Lire development we started supporting XML, and now all configuration is in XML, and the generated report is in XML. This can then further be converted to XHTML, PDF, etc... LogML was actually one of the possible output formats, but that project seems to have been abandonded. Chart generation is also done based on the XML report."
(Thanks, Egon!)
