<hr />
<p>Token for skipping over all undefined text until the matched
expression is found.</p>
<p>Parameters:</p>
<ul>
<li>
expr - target expression marking the end of the data to be skipped
</li>
<li>
include - (default=<code>False</code>) if True, the target expression
is also parsed (the skipped text and target expression are returned
as a 2-element list).
</li>
<li>
ignore - (default=<code>None</code>) used to define grammars
(typically quoted strings and comments) that might contain false
matches to the target expression
</li>
<li>
failOn - (default=<code>None</code>) define expressions that are not
allowed to be included in the skipped test; if found before the
target expression is found, the SkipTo is not a match
</li>
</ul>
<p>Example:</p>
<pre class="literalblock">
report = '''
Outstanding Issues Report - 1 Jan 2000
# | Severity | Description | Days Open
-----+----------+-------------------------------------------+-----------
101 | Critical | Intermittent system crash | 6
94 | Cosmetic | Spelling error on Login ('log|n') | 14
79 | Minor | System slow when running too many reports | 47
'''
integer = Word(nums)
SEP = Suppress('|')
# use SkipTo to simply match everything up until the next SEP
# - ignore quoted strings, so that a '|' character inside a quoted string does not match
# - parse action will call token.strip() for each matched token, i.e., the description body
string_data = SkipTo(SEP, ignore=quotedString)
string_data.setParseAction(tokenMap(str.strip))
ticket_expr = (integer("issue_num") + SEP
+ string_data("sev") + SEP
+ string_data("desc") + SEP
+ integer("days_open"))
