Handling of pageContentFilterXPath

[ilopata1]

I believe the correct handling when there are no nodes in the document that match the xPath specified in pageContentFilterXPath, then the document should not be processed. To implement this I would suggest inserting:

if ( pageContentFilterNodeList.size() == 0) {
return false;
}

after the line:

List pageContentFilterNodeList = xPathPageContentFilter.selectNodes(cleanedXmlHtml);
