I'm creating a word document using mailmerge in word and I need to show a block of word depending on a conditional var:
<<if [var]>>
show text
<</if>>
I'm build the json object to pass a word document in java like:
InputStream targetStream = new ByteArrayInputStream(objectMapper.writeValueAsString(object).getBytes());
JsonDataSource ds = new JsonDataSource(targetStream);
ReportingEngine engine = new ReportingEngine();
engine.setOptions(ReportBuildOptions.ALLOW_MISSING_MEMBERS);
engine.buildReport(docIstanza, ds, "obj");
docIstanza.getMailMerge().setFieldMergingCallback(new HandleFieldMerging());
I have a problem to understand how to use the if instruction in word document. The var is a Boolean.
Mail Merge and LINQ Reporting Engine are two different ways to fill the template with data. If you use LINQ Reporting Engine, then in your template you should simply put the condition as regular text.
https://docs.aspose.com/words/net/using-conditional-blocks/
If you use Mail Merge feature, you should use MS Word MergeFields
https://docs.aspose.com/words/java/mail-merge-template/
in this case to show conditional content, you should use IF fields.
In your case you get data from JSON and value of var variable is nullable Boolean. In this case you have to use <<if [var == true]>>

sorry if my terms are off, i havent done this before
Im using jsoup to scrape a single value off a website page,
I am trying to find the "serialno" which is stored within this function (java script?)
function set(obj, val)
{
document.getElementById(obj).innerHTML= val;
}
called by
{set("modelname", "NPort 5650-16");set("mac", "00:90:E8:22:76:F4");set("serialno", "2583");set("ver", "3.3 Build 08042219");setlabel("NPORT");uptime("264 days, 03h:31m:34s");}<
i am unsure how i can use jsoup to extract/print the serialno value, which in this case happens to be 2583. ive tried basic commands using getElementById but ive never used jsoup before. i am familiar with maps, but not sure how i can manipulate with jsoup, and most of the tutorials online need the actual 'path' to the exact cell within the table (where this info is displayed).
You can't use Jsoup to do this. Jsoup can parse HTML, but javascipt is out of its reach and is recognized as text. It can't be executed and selecting things from javascript is not possible.
But if you already have HTML parsed to Document and you're looking for an alternative solution you may try to use regular expressions to grab this value.
Document doc = Jsoup.parse...
String html = doc.toString();
Pattern p = Pattern.compile("set\\(\"serialno\", \"(\\d+)\"\\)");
Matcher m = p.matcher(html);
if (m.find()) {
String serialno = m.group(1);
System.out.println(serialno);
}
I am trying to understand on how to perform queries in Redisearch strictly with "begins with" and I keep getting "contains".
For example if I have fields with values like 'football', 'myfootball', 'greenfootball' and would provide a search term like this:
> FT.SEARCH myIdx #myfield:foot*
I want just to get 'football' but I keep getting other fields that contain the word instead of beginning with that word.
Is there a way to avoid this?
I was trying to use VERBATIM and things like #myfield:^foot* but nothing.
I am using JRedisearch as a client but eventually I had to enter the DB and perform these queries manually in order to figure out what's happening. That being said, is this possible to do with this client at the moment?
Thanks
EDIT
A sample of my index setup:
Client client = new Client(INDEX_NAME, url, PORT);
Schema sc = new Schema().addSortableTextField("url", 1.0); // using this field for query
client.dropIndex(true);
client.createIndex(sc, Client.IndexOptions.Default());
return client;
Sample document:
id: // random uuid
urlPath: myfootbal
application: web
market: Europe
After checking the RDB provided I see that when searching foot* you are not getting myfootbal. The replies look like this: /dot-com/plp/football/x/index.html. You are getting those replies because this url is tokenized, and '/' is one of the tokenize chars. If you do not want those urls to be tokenized you need to declare them as TAGS and not as TEXT. This way the entire url will be indexed as is and when search for foot* it will not appear in the results.
For more information about TAGS see the FT.CREATE documentation: https://oss.redislabs.com/redisearch/Commands.html
I am trying to extract data out of a website access log as part of a java program. Every entry in the log has a url. I have successfully extracted the url out of each record.
Within the url, there is a parameter that I want to capture so that I can use it to query a database. Unfortunately, it doesn't seem that the web developers used any one standard to write the parameter's name.
The parameter is usually called "course_id", but I have also seen "courseId", "course%3DId", "course%253Did", etc. The format for the parameter name and value is usually course_id=_22222_1, where the number I want is between the "_" and "_1". (The value is always the same, even if the parameter name varies.)
So, my idea was to use the regex /^.*course_id[^_]*_(\d*)_1.*$/i to find and extract the number.
In java, my code is
java.util.regex.Pattern courseIDPattern = java.util.regex.Pattern.compile(".*course[^i]*id[^_]*_(\\d*)_1.*", java.util.regex.Pattern.CASE_INSENSITIVE);
java.util.regex.Matcher courseIDMatcher = courseIDPattern.matcher(_url);
_courseID = "";
if(courseIDMatcher.matches())
{
_courseID = retrieveCourseID(courseIDMatcher.group(1));
return;
}
This works for a lot of the records. However, some records do not record the course_id, even though the parameter is in the url. One such example is the record:
/webapps/contentDetail?course_id=_223629_1&content_id=_3641164_1&rich_content_level=RICH&language=en_US&v=1&ver=4.1.2
However, I used notepad++ to do a regex replace on this (in fact, every) url using the regex above, and the url was successfully replaced by the course ID, implying that the regex is not incorrect.
Am I doing something wrong in the java code, or is the java matcher broken?
I tried many lucene analzers and found keyword analyzer to be the best match for my requirement. I am using the same keyword analyzer for both updating the document and searching the same using QueryParser.
I want to search for the values with wildcard support.
For example : if a field "country" contains the value "india"
I can search for the same field as "ind*", "ndi", india etc.
I am getting the match for all other searches except the exact match.
ie. when i am searching the exact word (country:india), i am not getting any match.
If i am changing the same query as "country:india*" or "country:indi?", i am getting the
match.
Also i have another doubt, if there is a country with the name "not", how can i search for the same.
I tried "country:"not"" and "country:\not". But both failed.
What is actually happening in both these cases?
Please help.
I suspect you have some whitespace or other extraneous characters after the country name. You could either trim your input before adding it to Lucene, or implement a custom keyword analyzer, and add a TrimFilter, something like:
public final class CustomKeywordAnalyzer extends Analyzer {
public CustomKeywordAnalyzer() {
}
#Override
protected TokenStreamComponents createComponents(final String fieldName, final Reader reader) {
Tokenizer tokenizer = new KeywordTokenizer(reader)
TokenStream filter = new TrimFilter(Version.LUCENE_43, tokenizer);
return new TokenStreamComponents(tokenizer, filter);
}
}
As far as searching for "not", it simply being lowercase should be adequate for it not to be interpreted as a boolean operator (AND, OR, and NOT operators must be uppercase, per the documentation). Those words will get caught by a standard English StopFilter though, such as the one used by StandardAnalyzer. Are you sure you are just using a KeywordAnalyzer when querying?
Barring that, though, the sure way to avoid query parser reserved words would be to just bypass the query parser entirely, and construct the query yourself:
Query query = new TermQuery(new Term("country", userQuery));
I'm trying to generate some conditions using string i get as input.
For example, i get as in put the string "length = 15" and i want to create from that the condition:
length == 15.
To be more specific, i have an int in my program called length and it is set to a specific value.
i want to get from the user a conditon as input ("length < 15" or "length = 15"....) and create an if statement that generates the condition and test it.
What is the best way of doing that?
Thanks a lot

Unless you're talking about code-generation (i.e. generating Java-code by input strings) you can't generate an if-statement based on a string.
You'll have to write a parser for your condition-language, and interpret the resulting parse trees.
In the end it would look something like this:
Condition cond = ConditionParser.parse("length = 15");
if (cond.eval()) {
// condition is true
}
Use a string tokenizer. The default method to distinguish between tokens (or the smallest parts of the input string) is white space, which is to your benefit.
check out javadocs for details:
http://docs.oracle.com/javase/1.3/docs/api/java/util/StringTokenizer.html
Depending on what restrictions you can place on your input format, you could consider using Rhino to embed Javascript. Your 'conditions' then just have to be valid JavaScript code. Something like this (disclaimer: haven't compiled it):
import javax.script.*;
public bool evalCondition (Object context, String javascript) {
ScriptEngine engine = new ScriptEngineManager().getEngineByName("javascript");
Object result = engine.eval(javascript);
Boolean condTrue = (Boolean)result;
return condTrue;
}
See the Embedding Rhino Tutorial for more details.
