写的一个TextPatternParser，可用于采集
//EXAMPLES $htmlPage = 'tab.html';$htmlPage = file_get_contents($htmlPage);

//$beginText = the begining value to search for, parseBetweenText looks between $beginText and $endText
//$endText = end value to look for
//$removeSpace - perform trim on value
//$removeHtmlTags - removes any html from end result array values
//$firstResultOnlyNoArray - only will return one result - the first one instead of an array
