I have a Yaml file that's something like below:
rules:
- p_table:
["p_event/Name",
"p_fault/Name"]
- s_table:
["s_event/Name",
"s_fault/Name"]
- r_table:
["r_event/Name",
"r_fault/Name"]
So, I can already take the .yml file above and parse through it with YamlBeans and print it out with code like below:
System.out.println(map.get("rules"));
This gives this kind of result:
[{p_table=[p_event/Name, p_fault/Name]},
{s_table=[s_event/Name, s_fault/Name]},
{r_table=[r_event/Name, r_fault/Name]}]
What I would like to do is more on this sort of level, where I can store it in a HashMap and actually use the specifics within the map, with something like this:
HashMap<String, ArrayList<Strings>> Policies = (HashMap)(map.get("rules"));
But when I do that I either have an exception thrown or it just returns null, is there a solution for this should I not be using HashMaps... or can I just not translate objects in such a way? I plan on replacing the String with another type from a different library that uses Strings but wanted to start at the bottom and then go up from there.
The obvious solution would be to remove the sequence from the YAML file:
rules:
p_table:
["p_event/Name",
"p_fault/Name"]
s_table:
["s_event/Name",
"s_fault/Name"]
r_table:
["r_event/Name",
"r_fault/Name"]
If you can't change the YAML file, you need to transform the data after loading it.

I'm trying to create a PreferenceActicity.
I need that on of my preferences will be of type MultiSelectedListPreference.
I found this code on the internet:
<MultiSelectListPreference
android:dialogTitle="#string/mode_repeat"
android:key="mode_repeat"
android:summary=""
android:title="#string/mode_repeat"
android:entries="#array/weekdays"
android:entryValues="#array/weekdays_values"
android:defaultValue="#array/empty_array"
/>
The problem is I'm getting the entries and entryValues in runtime.
I'm building the ArrayList while my app is running, the question is how can I set my ArrayList as the entries and as the entryValues?
Do I need to create an empty xml file, which I will re-write during the building of my list?
You wouldn't be able to change the xml in runtime. The solution for your problem is to use the methods setEntries()and setEntryValues()from the MultiSelectListPreference class.
Here's a basic code snippet:
MultiSelectListPreference repeatModePreference = (MultiSelectListPreference) findPreference(Constants. mode_repeat);
repeatModePreference.setEntries(yourEntries); // This is human-readable strings
repeatModePreference.setEntryValues(yourEntryvalues) // The value corresponding to the human-readable string
Hope this helps.
I am totally new to XML and its capabilities.
I have a file say xyz.xml.
It contains content like this:
<system-config>
<business-model>
<agent-category key="operator">
<singular-name>Operator</singular-name>
<plural-name>Operators</plural-name>
<attribute>agent-attribute.reference</attribute>
</agent-category>
Next I have
<agent-attribute id="agent-attribute.reference">
<name>Reference</name>
< description>A unique identifier for this agent, typically an MSISDN.</description>
<mandatory>true< /mandatory>
<editable>false< /editable>
<deletable>false< /deletable>
<sensitive>false< /sensitive>
<system-generated>false< /system-generated>
<input-method xsi:type="AgentReferenceInputMethod"></input-method>
<storage-location xsi:type="AgentRefStorage" field="reference"></storage-location>
</agent-attribute>
</business-model>
Now I want to distribute the agent-attributes to different file named agentAttr.xml.
Is it possible to do so (mind it <agent-attribute> is under <system-config><business-model>), if so how?
So you want to extract the agent-attribute portions ?. You can do that with simple XSLT transformation (use e.g. Xalan for that). Another option could be jsoup, parsing it using DOM or manually.
From a String like
<TestData Identifier=\"Test\" requiredAttribute=\"Present\"></TestData> <TestData Identifier=\"Test1\" requiredAttribute=\"Present1\"></TestData> <TestData Identifier=\"Test2\" requiredAttribute=\"Present2\"></TestData> <TestData Identifier=\"Test3\" requiredAttribute=\"Present3\"></TestData>
whats the best way to get the values of the attributes requiredAttribute i.e (Present,Present1,Present2...)
You can look into JAXB unmarshalling. Check out this page for more details, it should point to what you need
http://jaxb.java.net/tutorial/section_3_1-Unmarshalling-and-Using-the-Data.html#Unmarshalling and Using the Data
For basic XML parsing like this, I've found NanoXML # http://nanoxml.cyberelf.be/ to be about the easiest and mostlightweight.
Working with XML in Java send you down a long road to pain if you start using all the other libraries.
That's not XML - but you could do it with regex or by converting it to XML and parsing it out. The latter is probably more expensive. It depends on what the actual test data is and your requirements for it.
I have a properties file that says
window.1.height=100
window.1.width=80
window.2.height=50
window.2.width=30
window.3.height=150
window.3.width=100
I am using the PropertiesConfiguration class and reading the properties.
How can I know the count of windows in the properties. Is therea pattern search
I usually use something like
int i = 0;
String val;
for(;;) {
val = props.get("foo" + i);
if (null == val) {
break;
}
//process val
}
This places the constraint that the counter values must be contiguous.
There are a couple of things you can do if you have any control over the properties file itself. If you are locked into that format, I don't believe there is anything you can do.
However, if you are not locked into that format, here are a couple of solutions:
XML Configuration
Change from a properties file to an XML file format. Something like this:
<windows>
<window>
<width>80</width>
<height>100</height>
</window>
<window>
<width>30</width>
<height>50</height>
</window>
<window>
<width>100</width>
<height>150</height>
</window>
</windows>
Then use XMLConfiguration instead of PropertiesConfiguration. You could then call
config.getList("windows").size()
to get the count of windows.
Properties Configuration
Your other option, which still involves a properties file, is a little bit more contrived. Your properties file would change to look like this:
window.height=100
window.width=80
window.height=50
window.width=30
window.height=150
window.width=100
Then to get the number of windows you would call
config.getList("window.height").size();
However, using this method, you would have to change how you retrieve the values. For example, in order to get the width and height of the second window, you would use this:
config.getInteger("window.width(1)");
config.getInteger("window.height(1)");
Using parens, you can access an individual element of a list, using zero-based indicies. It is a little more difficult to understand, but it would work.
The api has it already onboard. See Configuration#subset
I am working on iphone application which contains HTTP Request and Response.
The format of the response is a key/value format compatible with the Java "Properties" stream format.
I want to store the response into a NSDictionay. Could you suggest me any way to do this?
Thank you.
sangee
Edit:
Thanks guyz for the quick replies!!!
is their any other ways to store them in NSSdictionay?
I just want to store the album name and description in an array like this:
mutablearray = [wrwr, dsf, my album];
could you please let me know if this possible or not?
Thanks again!!!
This is the response i got it for my HTTP request...

If you can, I would recommend serializing the data as JSON (or XML, if you have to) and parsing it using TouchJSON or a similar parser. If you really can't, then you'll have to implement your own parser--take a look at NSScanner.
Look at NSStream and the Stream Programming Guide for Cocoa.
Back in the day when Java was fully integrated into Cocoa, NSStream mapped onto Java streams. It still might. IIRC, (it's been a while) NSStream will return a properly populated NSDictionary from a Java stream.
Edit:
It looks like the text returned is just a space delimited hash which is the Java version of dictionary. It takes the form of key=value space key=value. The only tricky part is that some of the hashes are nested.
The first line for example is nested:
debug_album{
debug_gallery_version{
debug_user=admin
debug_user_type=Gallery_User
debug_user_already_logged_in{
server_version=2.12
status=0
status_text=Login successful.
}
}
}
You need a recursive scanner to parse that. The "key=space" pattern indicates a nested dictionary.
