The performance benefits of HTMLParser are clear and the // users of JMeter will benefit from the hard work the HTMLParser // team. For detailed information about HTMLParser, the project is // hosted on sourceforge at http://htmlparser.sourceforge.net/. // // HTMLParser was originally created by Somik Raha in 2000. Since then // a healthy community of users has formed and helped refine the // design so that it is able to tackle the difficult task of parsing // dirty HTML. Derrick Oswald is the current lead developer and was kind // enough to assist JMeter. // // contributed by Joshua Kerievsky package org.htmlparser.visitors; import org.htmlparser.Node; import org.htmlparser.tags.EndTag; import org.htmlparser.tags.Tag; import org.htmlparser.util.NodeList; public class TagFindingVisitor extends NodeVisitor { private String[] tagsToBeFound; private int count[]; private int endTagCount[]; private NodeList[] tags; private NodeList[] endTags; private boolean endTagCheck; public TagFindingVisitor(String[] tagsToBeFound) { this(tagsToBeFound, false); } public TagFindingVisitor(String[] tagsToBeFound, boolean endTagCheck) { this.tagsToBeFound = tagsToBeFound; this.tags = new NodeList[tagsToBeFound.length]; if (endTagCheck) { endTags = new NodeList[tagsToBeFound.length]; endTagCount = new int[tagsToBeFound.length]; } for (int i = 0; i < tagsToBeFound.length; i++) { tags[i] = new NodeList(); if (endTagCheck) endTags[i] = new NodeList(); } this.count = new int[tagsToBeFound.length]; this.endTagCheck = endTagCheck; } public int getTagCount(int index) { return count[index]; } public void visitTag(Tag tag) { for (int i = 0; i < tagsToBeFound.length; i++) if (tag.getTagName().equalsIgnoreCase(tagsToBeFound[i])) { count[i]++; tags[i].add(tag); } } public Node[] getTags(int index) { return tags[index].toNodeArray(); } public void visitEndTag(EndTag endTag) { if (!endTagCheck) return; for (int i = 0; i < tagsToBeFound.length; i++) if (endTag.getTagName().equalsIgnoreCase(tagsToBeFound[i])) { endTagCount[i]++; endTags[i].add(endTag); } } public int getEndTagCount(int index) { return endTagCount[index]; } } |
