in order to know the PYD is playing tricks we'd need to support using the
PYD, and then it's not a problem anymore. I'll open a bug on this
anyway to see if we can make the experience better, but I have no idea what sort
of time frame we'd be able to do this in (another option for us would be
to create an xpath wrapper around System.Xml.XPath which looks like pyxml, but
it'd not solve any larger problems around PYDs in general).</span></font></p></div><div><span class="q">

<p><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;">You're right, I did miss
that… Looking at this page: <a href="http://pyxml.sourceforge.net/topics/howto/section-install.html" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">http://pyxml.sourceforge.net/topics/howto/section-install.html

It would seem that you may be right about the Pyd's (it at least requires
a C compiler, making that likely – and almost guaranteeing it won't
work w/ IronPython).</span></font></p>
<p><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;"> </span></font></p>
<p><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;">Unfortunately we don't support
PYD's currently (and aren't likely to soon) so most likely this
won't currently work. If you absolutely need XPath support in the mean
time I'd suggest using .NET's XMLPath (and if you need to work on
both you could make a thin wrapper over either PyXml for CPython and
.NET's XPath support). For example:</span></font></p>

<p><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;">import System.Xml.XPath as XPath</span></font></p>
<p><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;"> </span></font></p>
