I've got a little problem with StringReader and can't figure out why.
If I use a Projekt.Properties.Ressource everything works fine.
But if I just want to use a specific path it doesn't read the xml.
StringReader str= new StringReader("C:/TestFolder/Test.xml");
StringReader str= new StringReader(#"C:/TestFolder/Test.xml");
Both ways don't work.
Solved:
I just have to use
XmlTextReader xReader = new XmlTextReader(#"C:/TestFolder/Test.xml");
without any Stringreader.

Original javascript code I like to port to Dart.
hterm.defaultStorage = new lib.Storage.Chrome(chrome.storage.sync);
I have tried
js.context['hterm']['defaultStorage'] =
new js.JsObject(js.context['lib']['Storage']['Chrome'], js.context['chrome']['storage']['sync']);
but this doest work as I expected. perhaps, because js.JsObject returns dart object.
Do I have to use JsObject.jsify ? it seems that jsify receive collection of dart object only.
I think it should work this way
js.context['hterm']['defaultStorage'] =
js.context['lib']['Storage'].callMethod('Chrome', [js.context['chrome']['storage']['sync']]);
I'm new to entity framework, please forgive me if my question is too simple.
I'm using EF5 build my project at the moment, there is one Function Import "GetStockItem" in my project, which calls a stored procedure and returns data from SP. Every time when I "Update Model from database" from Model Diagram, the update wizard reflects the changes of database without problem, but GetStockItem stops working. The error message when I call GetStockItem is:
"The value of EntityCommand.CommandText is not valid for a StoredProcedure command. The EntityCommand.CommandText value must be of the form 'ContainerName.FunctionImportName'."
The solution, as instructed in the error message is clear, all I need is to add ContainerName. before the FunctionImportName (GetStockItem in my case) in the context.cs file.
My question is how can I avoid the from happening every time when I update models from database? It's quite annoying to do this manual thing now and then, and it's easy to forget to do this then cause users' complaint.
Hope someone can enlighten me with charming solution! Cheers!
I just ran into this using EF5/DbContext. The solution I found was to edit the T4 template ([Model].Context.tt) that generates the DbContext.
In this file, locate the instructions for generating the ExecuteFunction call. For me, it started on line 288:
public string ExecuteFunction(EdmFunction edmFunction, string modelNamespace, bool includeMergeOption)
{
var parameters = _typeMapper.GetParameters(edmFunction);
var returnType = _typeMapper.GetReturnType(edmFunction);
var callParams = _code.StringBefore(", ", String.Join(", ", parameters.Select(p => p.ExecuteParameterName).ToArray()));
if (includeMergeOption)
{
callParams = ", mergeOption" + callParams;
}
return string.Format(
CultureInfo.InvariantCulture,
"return ((IObjectContextAdapter)this).ObjectContext.ExecuteFunction{0}(\"{1}\"{2});",
returnType == null ? "" : "<" + _typeMapper.GetTypeName(returnType, modelNamespace) + ">",
edmFunction.Name,
callParams);
}
Modify the return line so that edmFunction.Name is replaced with edmFunction.FullName and upon saving, the Function Import code will be regenerated using fully-qualified names.
I had a similar issue, I suggest not to change the context.cs file at all; only make sure the connection strings in app.config file generated by EF is the same in the calling project, especially the metadata that in the connection string is very important to be correct. If it helps, please mark this answer accepted otherwise send me the steps to reproduce this error.
I would like to grab the following value on this website with xquery. After trying for awhile I couldn't figure it out. Here is what I am trying to fetch (image link)
And the code I tried using:
$xpath = new DOMXPath( $html );
$nodelist = $xpath->query( "???????????????" );
Any ideas?
You can try to grep the value between script tags
Like
//form/div/div/div[#class="values span-7"]/skipt/Text()
After parse the value in PHP other language hat you use to get your string
Can you get the value off of the input?
//form//input[#name="val7"]/#value
Update:
You can get the stuff in the script tag, but that's as far as you can get using xpath. You'll then need to parse the contents of the script tag in order to get that value.
//form[#id="werte"]//div[#class="calval7"]//div[#class="values"][1]/script/text()
I have a string (from HTTP Header) and want to split it into a dictionary.
foo = \"bar\",baz=\"fooz\", beta= \"gamma\"
I ca not guarantee that the string is the same every time. Maybe there are spaces, maybe not, sometimes the double quotes are escaped, sometimes not.
So I found the solution in PHP with regular expressions. Unfortunately I can't convert it to work on iOS.
preg_match_all('#('.$key.')=(?:([\'"])([^\2]+?)\2|([^\s,]+))#', $input, $hits, PREG_SET_ORDER);
foreach ($hits as $hit) {
$data[hit[1]] = $hit[3] ? $hit[3] : $hit[4];
}
Can anybody help me converting this to Objective-C?
I met a guy which is kinda RegEx guru. He explained the whole stuff and I got the following (working!!!!) solution in RegEx.
This gives me strings like foo="bar":
(?<=[,\\s])((realm|qop|nonce|opaque)=(?:([\"'])([^\2]+?)\2|([^\\s,]+)))
I then use another RegEx to split it by key and value to create a dictionary.
I have an XML as input to a Java function that parses it and produces an output. Somewhere in the XML there is the word "stratégie". The output is "stratgie". How should I parse the XML as to get the "é" character as well?
The XML is not produced by myself, I get it as a response from a web service and I am positive that "stratégie" is included in it as "stratégie".
In the parser, I have:
public List<Item> GetItems(InputStream stream) {
try {
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(stream);
doc.getDocumentElement().normalize();
NodeList nodeLst = doc.getElementsByTagName("item");
List<Item> items = new ArrayList<Item>();
Item currentItem = new Item();
Node node = nodeLst.item(0);
if (node.getNodeType() == Node.ELEMENT_NODE) {
Element item = (Element) node;
if(node.getChildNodes().getLength()==0){
return null;
}
NodeList title = item.getElementsByTagName("title");
Element titleElmnt = (Element) title.item(0);
if (null != titleElmnt)
currentItem.setTitle(titleElmnt.getChildNodes().item(0).getNodeValue());
....
Using the debugger, I can see that titleElmnt.getChildNodes().item(0).getNodeValue() is "stratgie" (without the é).
Thank you for your help.
I strongly suspect that either you're parsing it incorrectly or (rather more likely) it's just not being displayed properly. You haven't really told us anything about the code or how you're using the result, which makes it hard to give very concrete advice.
As ever with encoding issues, the first thing to do is work out exactly where data is getting lost. Lots of logging tends to be the way forward: create a small test case that demonstrates the problem (as small as you can get away with) and log everything about the data. Don't just try to log it as raw text: log the Unicode value of each character. That way your log will have all the information even if there are problems with the font or encoding you use to view the log.

You can either use utf-8 and have the 'é' char in your document instead of é, or you need to have a parser that understand this entity which exists in HTML and XHTML and maybe other XML dialects but not in pure XML : in pure XML there's "only" ", <, > and maybe ' I don't remember.
Maybe you can need to specify those special-char entities in your DTD or XML Schema (I don't know which one you use) and tell your parser about it.
