Den Parsing-Tree selbst bekommt man nicht so einfach, man kann aber das
Ergebnis für eine Weiterverarbeitung schon bei der Definition der Grammatik
beeinflussen z.B. durch Gruppierungen mit der Group-Klasse. Weiterhin kann man
sich durch Parsing-Aktions bei der Erkennung der Tokens registrieren und damit
schon eine spätere Weiterverarbeitung beeinflussen. Also - ohne die Grammatik
gesehen zu haben - sollte es doch z.B. ausreichend sein am Ende eine Liste zu
haben, bei dem jedes Element einem Intrawikilink entspricht. Letztendlich
kann auch der Output eine baumartige Struktur haben, wenn man die Grammatik entsprechend
definiert hat. Beispiele dafür sind die Hilfsfunktionen operatorPrecedence und
nestedExpr (wenn man die Ergebnisse auf Basis von asList() verarbeitet, bekommt
man eine Liste von Elemente, die wiederum Listen enthält). Ansosnten die Frage
direkt mal beim Entwickler posten.</span></font><o:p></o:p></p>

<br>
<font size=2><span style='font-size:10.0pt'>Ich habe mich vor ein paar Monaten
schon mal mit pyparsing versucht, war </span></font><br>
<font size=2><span style='font-size:10.0pt'>damals aber nicht sehr erfolgreich.
Vieleicht kann mir ja der Mensch der </span></font><br>
<font size=2><span style='font-size:10.0pt'>den Pyparsing Vortrag gehalten hat
weiter helfen. Siehe unten.</span></font> <br>

<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'><o:p> </o:p></span></font></p>
<p><font size=2 face="Times New Roman"><span style='font-size:10.0pt'>I am
trying to get started with the pyparing. I am working on a programm </span></font><br>
<font size=2><span style='font-size:10.0pt'>that read files in the mediawiki
format and write files in the latex </span></font><br>
<font size=2><span style='font-size:10.0pt'>format. I currently have got a
problem with the "|" character since it </span></font><br>
<font size=2><span style='font-size:10.0pt'>is used as a seperator inside an
intrawikilink as well as a seperator </span></font><br>
<font size=2><span style='font-size:10.0pt'>for cells in a table, which
naturaly causes problems with tables which </span></font><br>
<font size=2><span style='font-size:10.0pt'>contain intrawikilinks. As far as I
found out pyparsing is able to solve </span></font><br>
<font size=2><span style='font-size:10.0pt'>this problem in a good way.</span></font>
<br>
<font size=2><span style='font-size:10.0pt'>So I tryed to write a grammer for a
wikilink, which is given in the </span></font><br>
<font size=2><span style='font-size:10.0pt'>attached file. There is a problem
with the asXML function. You may look </span></font><br>
<font size=2><span style='font-size:10.0pt'>at the output when you run the
program comparing it with the multiline </span></font><br>
<font size=2><span style='font-size:10.0pt'>docstring given in the sourcecode.
Essetially I would have expected the </span></font><br>
<font size=2><span style='font-size:10.0pt'>output to be similar to the
docstring. But it is much different. </span></font><br>
<font size=2><span style='font-size:10.0pt'>Pyparsing writes a list like
structure and I expected a tree like </span></font><br>
<font size=2><span style='font-size:10.0pt'>structure. I often heard the term
parse tree. So how is it possible to </span></font><br>
<font size=2><span style='font-size:10.0pt'>access the parse tree that pypasing
creates. The list view of the </span></font><br>
<font size=2><span style='font-size:10.0pt'>parsetree does not seem to be
useful for my problem. The second problem </span></font><br>
<font size=2><span style='font-size:10.0pt'>I have is that I want to run
pyparsing on a unicode file that I open </span></font><br>
<font size=2><span style='font-size:10.0pt'>with
codecs.open("text","r","utf8"). So there are very
many possible </span></font><br>
<font size=2><span style='font-size:10.0pt'>characters that I do not want to
list in my sourcecode. So how can I </span></font><br>
<font size=2><span style='font-size:10.0pt'>write down a grammer expression
that machtes a series of arbitrary </span></font><br>
<font size=2><span style='font-size:10.0pt'>characters, which does not include
certain specifically mentioned </span></font><br>
<font size=2><span style='font-size:10.0pt'>charactes.</span></font> <br>
