Question

I have XHTML content, and I have to create from this content a PDF file on the fly. I use iText pdf converter. I tried the simple way, but I always get bad result after call

Here's a workaround for nested ordered and un-ordered lists.

The rich Text editor I am using giving the class attribute "ql-indent-1/2/2/" for li tags, based on the attribute adding ul/ol starting and ending tags.

public String replaceIndentSubList(String htmlContent) {
    org.jsoup.nodes.Document document = Jsoup.parseBodyFragment(htmlContent);
    Elements element_UL = document.select("ul");
    Elements element_OL = document.select("ol");
    if (!element_UL.isEmpty()) {
        htmlContent = replaceIndents(htmlContent, element_UL, "ul");
    }
    if (!element_OL.isEmpty()) {
        htmlContent = replaceIndents(htmlContent, element_OL, "ol");
    }
    return htmlContent;
}


public String replaceIndents(String htmlContent, Elements element, String tagType) {
    String attributeKey = "class";
    String startingULTgas = "<" + tagType + ">";
    String endingULTags = "";
    int lengthOfQLIndenet = new String("ql-indent-").length();
    HashMap startingLiTagMap = new HashMap();
    HashMap lastLiTagMap = new HashMap();
    Pattern regex = Pattern.compile("ql-indent-\\d");
    HashSet hash_Set = new HashSet();
    Elements element_Tag = element.select("li");
    for (org.jsoup.nodes.Element element2 : element_Tag) {
        org.jsoup.nodes.Attributes att = element2.attributes();
        if (att.hasKey(attributeKey)) {
            String attributeValue = att.get(attributeKey);
            Matcher matcher = regex.matcher(attributeValue);
            if (matcher.find()) {
                if (!startingLiTagMap.containsKey(attributeValue)) {
                    startingLiTagMap.put(attributeValue, element2.toString());
                }
                hash_Set.add(matcher.group(0));
                if (!startingLiTagMap.get(attributeValue)
                        .equalsIgnoreCase(element2.toString())) {
                    lastLiTagMap.put(attributeValue, element2.toString());
                }
            }
        }
    }
    System.out.println(htmlContent);
    Iterator value = hash_Set.iterator();
    while (value.hasNext()) {
        String liAttributeKey = (String) value.next();
        int noOfIndentes = Integer
                .parseInt(liAttributeKey.substring(lengthOfQLIndenet));
        if (noOfIndentes > 1)
            for (int i = 1; i < noOfIndentes; i++) {
                startingULTgas = startingULTgas + "<" + tagType + ">";
                endingULTags = endingULTags + "";
            }
        htmlContent = htmlContent.replace(startingLiTagMap.get(liAttributeKey),
                startingULTgas + startingLiTagMap.get(liAttributeKey));
        if (lastLiTagMap.get(liAttributeKey) != null) {
            System.out.println("Inside last Li Map");
            htmlContent = htmlContent.replace(lastLiTagMap.get(liAttributeKey),
                    lastLiTagMap.get(liAttributeKey) + endingULTags);
        }
        else {
            htmlContent = htmlContent.replace(startingLiTagMap.get(liAttributeKey),
                    startingLiTagMap.get(liAttributeKey) + endingULTags);
        }
        startingULTgas = "<" + tagType + ">";
        endingULTags = "";
    }
    System.out.println(htmlContent);[enter image description here][1]
    return htmlContent;
