Steven Rowe commented on LUCENE-3690:
-------------------------------------
bq. some test docs that contain almost no HTML at all
I used the following to test the zero-markup case in both test classes (the
{{JFlexHTMLStripParser}} version is given below):
{code:java}
public void testRandomText() throws Exception {
StringBuilder text = new StringBuilder();
int minNumWords = 10;
int maxNumWords = 10000;
int minWordLength = 3;
int maxWordLength = 20;
int numWords = _TestUtil.nextInt(random, minNumWords, maxNumWords);
switch (_TestUtil.nextInt(random, 0, 4)) {
case 0: {
for (int wordNum = 0 ; wordNum < numWords ; ++wordNum) {
text.append(_TestUtil.randomUnicodeString(random, maxWordLength));
text.append(' ');
}
break;
}
case 1: {
for (int wordNum = 0 ; wordNum < numWords ; ++wordNum) {
text.append(_TestUtil.randomRealisticUnicodeString
(random, minWordLength, maxWordLength));
text.append(' ');
}
break;
}
default: { // ASCII 50% of the time
for (int wordNum = 0 ; wordNum < numWords ; ++wordNum) {
text.append(_TestUtil.randomSimpleString(random));
text.append(' ');
}
}
}
Reader reader = new JFlexHTMLStripCharFilter
(CharReader.get(new StringReader(text.toString())));
while (reader.read() != -1);
}
{code}
The results for 10K iterations (best/worst of 5):
* {{HTMLStripCharFilter}}: best: 23.7 sec, worst: 24.8 sec
* {{JFlexHTMLStripCharFilter}}: best: 22.0 sec, worst: 24.7 sec
> JFlex-based HTMLStripCharFilter replacement
