    A utility to get the version from the catalog root.
    
    Parameters:
    
    node - The xml node
    
    Returns:
    
    The version
  - haveChildDatasets
```
public static boolean haveChildDatasets(org.w3c.dom.Element node)
```
  - haveChildCatalogs
```

```
  - getServiceType
```
public static java.lang.String getServiceType(org.w3c.dom.Element serviceNode)
```
    Find the service type attribute for the given service node. This is thredds version specific - looking for either "servicetype" attribute or "type" attr.
    
    Parameters:
    
    serviceNode - The service node to look for the service type.
    
    Returns:
    
    The service type attribute or null if not found.
  - getTitleFromDataset
```
public static java.lang.String getTitleFromDataset(org.w3c.dom.Element datasetNode)
```
    Assemble the String title for the given dataset. We look for the first two "name" attributes in the xml tree and concatenate them (If found).
    
    Parameters:
    
    datasetNode - The dataset node we are looking at.
    
    Returns:
    
    The title for this dataset node. (may be null).
  - errorMessage
```
public static void errorMessage(java.lang.String msg)
```
    Log the error
    
    Parameters:
    
    msg - the error message
  - findServiceNodeForDataset
```
public static org.w3c.dom.Element findServiceNodeForDataset(org.w3c.dom.Element datasetNode,
                                                            boolean showErrors,

```
    Find the service xml element for the given dataset node. First, we look for any service nodes contained by the dataset node. If not found then we find the service name from the dataset node. If no service name attrbiute is found then print an error and return null. Now, we search the xml tree under the root node to find a service node with the given name. If not found then print an error and return null.
    
    Parameters:
    
    datasetNode - The dataset node to look for a service node for.
    
    showErrors - Do we tell the user if there was an error
    
    type - service type
    
    Returns:
    
    Return the service node or null if not found.

```
    Recurse up the DOM tree, looking for a dataset that contains a dataType attribute. We also look at "access" nodes contained by the dataset node.
    
    Parameters:
    
    datasetNode - The dataset node we are looking at.
    
    root - The root of the xml tree
    
    version - The catalog version<
    
    firstCall - Is this the leaf node
    
    Returns:
    
    The name of the service that provides this dataset.
  - getAbsoluteUrl
```
public static java.lang.String getAbsoluteUrl(org.w3c.dom.Element serviceNode,
                                              java.lang.String urlPath)
```
    Find the base url for the given service node. If not found print an error and return null. If found then look for the "suffix" attribute of the service node. If found append it to the urlPath. Return the base concatenated with the urlPath.
    
    Parameters:
    
    serviceNode - The service node for the given urlPath.
    
    urlPath - The tail end of the absolute url.
    
    Returns:
    
    The full url path.
  - getUrlPath
```
public static java.lang.String getUrlPath(org.w3c.dom.Element datasetNode)
```
    Lookup and return the urlPath defined for the given datasetNode.
    
    Parameters:
    
    datasetNode - The dataset node we are looking at.
    
    Returns:
    
    The url path for the dataset node.
  - getResolverData
```
public static java.lang.Object[] getResolverData(java.lang.String resolverUrl,
                                                 java.util.Hashtable properties)
```
    This reads the xml pointed to by the given resolverUrl. It flags an error if the url is bad, the xml is bad, the xml contains 0 dataset nodes, the xml contains more than one dataset node. It returns an array of object which contain:
```
        Object[] {newXmlRoot, datasetNode, serviceNode, url}
  
```
    Parameters:
    
    resolverUrl - The url pointing to the resolver catalog.
    
    properties - The properties
    
    Returns:
    
    Array of root element, dataset node, service node and the absolute url of the data.
  - resolveUrl
```
public static java.lang.String resolveUrl(java.lang.String resolverUrl,
                                          java.util.Hashtable properties)
```
    The given resolverUrl should return a catalog that holds one dataset. This method returns the absolute url that that catalog holds. If the given properties is no null then this will also try to extract the title from the xml and will put the PROP_TITLE into the properties.
    
    Parameters:
    
    resolverUrl - The url pointing to the resolved catalog.
    
    properties - To put the title into.
    
    Returns:
    
    The absolute url that the resolverUrl resolves to (may be null).
  - addServiceProperties
```
public static void addServiceProperties(org.w3c.dom.Element datasetNode,
                                        java.util.Hashtable properties,
                                        java.lang.String urlPath)
```
    Add any service urls to the properties
    
    Parameters:
    
    datasetNode - data set node
    
    properties - properties
    
    urlPath - base url
  - generateHtml
```
public static int generateHtml(org.w3c.dom.Element root,
                               org.w3c.dom.Element datasetNode,
                               int cnt,
                               java.lang.String bundleTemplate,
                               java.lang.String jnlpTemplate)
```
    Generate an html representation of the catalog
    
    Parameters:
    
    root - Root of the catalog
    
    datasetNode - The data set node we are looking at
    
    cnt - The current count of the data set nodes we have processed
    
    bundleTemplate - The bundle template we generate the bundle from
    
    jnlpTemplate - The jnlp template
    
    Returns:
    
    The current count
