nodes

Is it possible to create/delete different databases in the graph database Neo4j like in MySQL? Or, at least, how to delete all nodes and relationships of an existing graph to get a clean setup for tests, e.g., using shell commands similar to rmrel or rm ? Peter Neubauer You can just remove the entire graph directory with rm -rf , because Neo4j is not storing anything outside that: rm -rf data/* Also, you can of course iterate through all nodes and delete their relationships and the nodes themselves, but that might be too costly just for testing ... even more simple command to delete all nodes

I have what should be an easy task: delete <places> nodes and their descendants from an XML document, leaving other nodes. I tried this code, but it did not work ... $document->preserveWhiteSpace = false; $books = $xpath->query('piletilve_info/places'); //echo "4"; foreach ($books as $places) { while($places->hasChildNodes()) { $places->removeChild($places->childNodes->item(0)); } $places->parentNode->removeChild($places); } Source XML to be processed: <piletilve_info> <places> <place> ... </place> </places> <other node> ... </other node> </piletilve_info> In the actual data there are more

I am new to XSLT and changing it manually will take a lot of time. <GroupData ID="xxx" Key="4" Temp="yyy"> <ItemData ID="zzz" Value="3"/> </GroupData> <GroupData ID="xxx" Key="4" Temp="yyy"> <ItemData ID="www" Value="1982"/> </GroupData> I want to have the childs of these multiple GroupData nodes within the same group, i.e., <GroupData ID="xxx" Key="4" Temp="yyy"> <ItemData ID="zzz" Value="3"/> <ItemData ID="www" Value="1982"/> </GroupData> So I need to merge/combine/match them on both GroupData's ID and Key attributes (these vary within the file). Also some do not have a Key attribute. How

I am using var win1 = open.window(...); var win2 = open.window(...); to open 2 tabs/windows in Firefox - now I want to compare the two DOMs (document object models) for similarity. So I have got two DOMs containing a very similar page. The pages have the same HTML but executed different JavaScript files. In general I check if HTML and CSS is the same: var html1 = win1.document.body.innerHTML; var html2 = win2.document.body.innerHTML; if (html1 == html2) { ... } var css1 = win1.document.body.style.cssText var css2 = win2.document.body.style.cssText if (css1 == css2) { ... } But comparing all

I am practicing working with Linked List Nodes and have come upon a problem I don't know how to answer. How do you go about deleting the last node in a linked list. The code below works for all entry's bar the last node. The last does not get deleted. Node Class public class Node { private String data; private Node next; Node(String data, Node next) { this.data = data; this.next = next; } public void setData(String d) { data = d; } public void setNext(Node n) { next = n; } public String getData() { return data; } public Node getNext() { return next; } Main Node list = new Node("NODE 1",new
