Vim with C Conditional Parsing


Vim with C Conditional Parsing

I think the issue was by ths following , With the ancient ifdef highlighting plugin, you can :Define or :Undefine preprocessor defines, and the corresponding blocks with be highlighted or not. Apart from that, I'll second @FDinoff's comment: Vim is a text editor, and there are no provisions for extending the tags handling and other lookups. Vim only has a basic understanding of a programming language via syntax scripts, not an entire compiler infrastructure like an IDE.

How to do conditional parsing with fscanf?

How to do conditional parsing with fscanf?

wish of those help I found a crude way to do, what I wanted without having to switch to fgets (which would probably be safer on the long run).
code :
if (fscanf(stream,"%d ",&x)){...}
else if (fscanf(stream,"%d:%g",&y,&z)){...}
else if (fscanf(stream,":%g",&z)){
    y=x;
    x=0;
}

This might help you In the startElement method of your ContentHandler you can simply throw a SAXException to abort parsing when your validated attribute has the value True.
For example:
code :
@Override
public void startElement(final String uri, final String localName,
    final String qName, final Attributes attributes) throws SAXException {

    if(localName.equalsIgnoreCase("employee") || localName.equalsIgnoreCase("street")) {
        final String validated = attributes.getValue("validated");
        if(validated != null && !validated.equals("False")) {
            throw new SAXException(localName + " has already been validated");
        } else {
            //your processing logic here
        }
    }

wish helps you I am writing a pdf parsing library. , UPDATE After the comment:
code :
start = 
    (
        ( object_number >> generation_number 
        | qi::attr(1) > qi::attr(0) // defaults
        ) >> "obj" >> object > "endobj"
    | qi::attr(1) >> qi::attr(0) >> object
    )
    ;
start = 
       -qi::omit [ object_number >> generation_number ]
    >> "obj" >> object > "endobj"
    ;
start = 
       ( object_number >> generation_number 
       | qi::attr(1) > qi::attr(0) // defaults
       )
    >> "obj" >> object > "endobj"
    ;

Hope that helps I suggest a recursive search through your Document object, since what you're looking for is a few levels deep.
Make a function that recursively calls itself passing what node you're currently on along with what tag you're looking and the value that tag must have.
code :
public static void main(String[] args) throws Exception {
    String xml
            = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n"
            + "<Shapes>\n"
            + " <Shape>\n"
            + "     <ShapeType>H2</ShapeType>\n"
            + "     <Annotation>\n"
            + "         <Properties>\n"
            + "             <PropertyValue PropertyName=\"field_label\">label.modelSeriesCd</PropertyValue>\n"
            + "             <PropertyValue PropertyName=\"ContainerType\">conditionContainer</PropertyValue>\n"
            + "         </Properties>\n"
            + "     </Annotation>\n"
            + "     <FootnoteNumber>1</FootnoteNumber>\n"
            + "     <Name>label.modelSeriesCd</Name>\n"
            + "     <Rectangle>\n"
            + "         <Rectangle X=\"14\" Y=\"94\" Width=\"43\" Height=\"12\" />\n"
            + "     </Rectangle>\n"
            + " </Shape>\n"
            + " <Shape>\n"
            + "     <ShapeType>H2</ShapeType>\n"
            + "     <Annotation>\n"
            + "         <Properties>\n"
            + "             <PropertyValue PropertyName=\"field_label\">label.modelSeriesMd</PropertyValue>\n"
            + "             <PropertyValue PropertyName=\"ContainerType\">mContainer</PropertyValue>\n"
            + "         </Properties>\n"
            + "     </Annotation>\n"
            + "     <FootnoteNumber>1</FootnoteNumber>\n"
            + "     <Name>label.modelSeriesCd</Name>\n"
            + "     <Rectangle>\n"
            + "         <Rectangle X=\"14\" Y=\"94\" Width=\"43\" Height=\"12\" />\n"
            + "     </Rectangle>\n"
            + " </Shape>\n"
            + "</Shapes>";

    Document xmlDocument = DocumentBuilderFactory
            .newInstance()
            .newDocumentBuilder()
            .parse(new InputSource(new ByteArrayInputStream(xml.getBytes("utf-8"))));

    Node node = findPropertyTagAndValue(xmlDocument.getFirstChild(), "PropertyValue", "conditionContainer");
    if (node != null) {
        System.out.println("Node Name = " + node.getNodeName() + "; Value = " + node.getTextContent());
    }
}

    if (node == null) {
        // The node we're looking for does not exist
        return null;
    } else if (node.getNodeType() != Node.ELEMENT_NODE) {
        // Move to the next sibling node
        return findPropertyTagAndValue(node.getNextSibling(), propertyTag, propertyValue);
    } else if (node.getNodeName().equalsIgnoreCase(propertyTag) && node.getTextContent().equalsIgnoreCase(propertyValue)) {
        // We found the node we are looking for
        return node;
    } else if (node.hasChildNodes()) {
        // Check into the child nodes
        Node childNode = findPropertyTagAndValue(node.getFirstChild(), propertyTag, propertyValue);
        if (childNode == null) {
            // Nothing found in child node, so move to next sibling
