I have simple question, Is it possible to escape package name in Spring-EL function T(..)?
The reason why I need this is because I live in Lithuania and all our packages start with country code lt f.e. lt.aaa.bbb.ccc. As you could expect this something we can not change.
Now, when I try to use SpEL to access some constant or static function in my classes I write:
#{T(lt.aaa.bbb.ccc).CONSTANR_VAR}, but this doesn't work, because SpEL parses expression and interprets lt as 'Less Then' not as part of package. This should be a problem for country codes gt, eq etc.
Is there any way around this, or are we just wery unlucky?
I can't immediately think of a workaround. I created:
https://jira.springsource.org/browse/SPR-10942
against the spring framework to cover the problem. I have SpEL open up at the moment as I'm working on something so I might try to get this fixed soon.

I've been using the first version of PHRets v1 for years, and understood it well enough to get by, but now I'm trying to understand the advantages of v2.6.2. I've got it all installed and the basics are working fine. My issues are pretty much with comprehending fine points of query syntax that goes into the rets=>Search() statement. (I'm much more familiar with SQL statements). Specifically, I'd like to have a query return a list of properties, EXCLUDING those which already have the status of "Sold".
Here's where I am stuck: If I start with this
`$results = $rets->Search('Property', 'A','*',['Select' => 'LIST_8,LIST_105,LIST_15,LIST_19,listing_office_shortid']);`
That works well enough. BUT I'd like to fit in a filter like:
"LIST_15 != Sold", or "NOT LIST_15=Sold"...something like that. I don't get how to fit/type that into a PHRets Search().
I like PHRets but it is so hard to find well-organized/complete documentation about specific things like this. Thanks in advance.
As in my comment above I've figured out that the filter goes in the third argument position ('*', as in the original question). The tricky thing was having to find a specific "sold" code for each class of properties and placing it in that position like so: '(LIST_15=~B4ZIT1Y75TZ)', (notice the =~ combination of characters that means "does not equal" in this context). I've found the code strings for each of the property types (not clear WHY they would need to be unique for each type of property: "Sold" is Sold for any type, after all) but the correct code for a single-family residential property (type 'A' ...at least for the MLS in which I have to search is:
$results = $rets->Search('Property', 'A','(LIST_15=~B4ZIT1Y75TZ)',['Select' => 'LIST_8,LIST_105,LIST_15,LIST_19,listing_office_shortid']);
(again, the code to go with LIST_15 will be different for the different types of properties.) I think there is a better answer that involves more naturalistic language, but this works and I guess I will have to be satisfied with it for now. I hope this is of some use to anyone else struggling with this stuff.
My current issue is to find HTML-Tags inside of property values. I thought it would be easy to search with a query like /jcr:root/content/xgermany//*[jcr:contains(., '<strong>')] order by #jcr:score
It looks like there is a problem with the chars < and > because this query finds everything which has strong in it's property. It finds <strong>Some Text</strong> but also This is a strong man.
Also the Query Builder API didn't helped me.
Is there a possibility to solve it with a XPath or SQL Query or do I have to iterate through the whole content?
I don't fully understand why it finds This is a strong man as a result for '<strong>', but it sounds like the unexpected behavior comes from the "simple search-engine syntax" for the second argument to jcr:contains(). Apparently the < > are just being ignored as "meaningless" punctuation.
You could try quoting the search term:
/jcr:root/content/xgermany//*[jcr:contains(., '"<strong>"')]
though you may have to tweak that if your whole XPath expression is enclosed in double quotes.
Of course this will not be very robust even if it works, since you're trying to find HTML elements by searching for fixed strings, instead of actually parsing the HTML.
If you have an specific jcr:primaryType and the targeted properties you can do something like this
select * from nt:unstructured where text like '%<strong>%'
I tested it , but you need to know the properties you are intererested in.
This is jcr-sql syntax
Start using predicates like a champ this way all of this will make sense to you!
HTML Encode <strong>
HTML Decimal <strong>
Query builder is your friend:
Predicates: (like a CHAMP!)
path=/content/geometrixx
type=nt:unstructured
property=text
property.operation=like
property.value=%<strong>%
Have go here:
http://localhost:4502/libs/cq/search/content/querydebug.html?charset=UTF-8&query=path%3D%2Fcontent%2Fgeometrixx%0D%0Atype%3Dnt%3Aunstructured%0D%0Aproperty%3Dtext%0D%0Aproperty.operation%3Dlike%0D%0Aproperty.value%3D%25%3Cstrong%3E%25
Predicates: (like a CHAMP!)
path=/content/geometrixx
type=nt:unstructured
property=text
property.operation=like
property.value=%<strong>%
Have a go here:
http://localhost:4502/libs/cq/search/content/querydebug.html?charset=UTF-8&query=path%3D%2Fcontent%2Fgeometrixx%0D%0Atype%3Dnt%3Aunstructured%0D%0Aproperty%3Dtext%0D%0Aproperty.operation%3Dlike%0D%0Aproperty.value%3D%25%26lt%3Bstrong%26gt%3B%25
XPath:
/jcr:root/content/geometrixx//element(*, nt:unstructured)
[
jcr:like(#text, '%<strong>%')
]
SQL2 (already covered... NASTY YUK..)
SELECT * FROM [nt:unstructured] AS s WHERE ISDESCENDANTNODE([/content/geometrixx]) and text like '%<strong>%'
Although I'm sure it's entirely possible with a string of predicates, it's possibly heading down the wrong route. Ideally it would be better to parse the HTML when it is stored or published.
The required information would be stored on simple properties on the node in question. The query will then be a lot simpler with just a property = value query, than lots of overly complex query syntax.
It will probably be faster too.
So if you read in your HTML with something like HTMLClient and then parse it with a OSGI service, that can accurately save these properties for you. Every time the HTML is changed the process would update these properties as necessary. Just some thoughts if your SQL is getting too much.
Could you please help me on this xpath expression evaluation
I am working on fetching the proxy references. In the xml file the references will get stored as:
One way of XML file will have the reference as below:
con1:service ref="MyProject/ProxyServices/service1"
xsi:type="con2:PipelineRef" xmlns:ref="http://www.bea.com/wli/sb/reference"/
here in the xml file the name spaces are:
xmlns:con1="http://www.bea.com/wli/sb/stages/config"
xmlns:con2="http://www.bea.com/wli/sb/pipeline/config"
Another way of XML will have the reference as below.
con1:service ref="MyProject/ProxyServices/service2"
xsi:type="ref:ProxyRef" xmlns:ref="http://www.bea.com/wli/sb/reference"/
here in the xml file the name spaces are:
xmlns:con1="http://www.bea.com/wli/sb/stages/config"
xmlns:ref="http://www.bea.com/wli/sb/reference"
I have used this xpath expression, this is not fetching the reference service values, could you please help what is wrong in it.
"//service[#type= #*[local-name() ='ProxyRef' or #type=#*[local-name() ='PipelineRef']]/#ref"
when I used like this it is working but, name space prefix is keep on changes when there are multiple references in the xml file.
"//service[#type='ref:ProxyRef'or #type='con:PipelineRef' or #type='con1:PipelineRef' or #type='con2:PipelineRef' or #type='con3:PipelineRef' ...#type='con20:PipelineRef' ]/#ref";
Now here basically the type attribute PipelineRef is keep on changing the name space prefix from con to con(n). Now I am looking for something which supports some thing like #type='*:PipelineRef' or #type='con*:PipelineRef' or the best way to fetch the service element reference attribute value.
Thanks in advance.
Try using contains() like so :
//service[contains(#type,':ProxyRef') or contains(#type,':PipelineRef')]
Another alternative would be using ends-with() function which is more precise for this purpose compared to contains() function. However, ends-with() isn't available in xpath 1.0, so there is a chance that you need to implement it yourself (feasible, but the xpath result is less intuitive for me).
Let me start with I'm not a programmer by trade, but I'm learning the best I can. I'm trying to build a template to take the result of one FreeMarker interpolation result and use that as a variable for another. I hope I'm using the terms correctly.
For example, I want the result of (entity.customer.organization.name) to be used in:
${blurb["organizationXXXAttire"]!}
Where XXX is the result of (entity.customer.organization.name)
If it was just a blurb with out a variable company name it would look like:
${blurb["organizationCompanyAttire"]!}
I thought the following would work but it did not:
<#assign organization = (entity.customer.organization.name)>
${blurb["organization<#organization?interpret>Attire"]!}
Thanks in advance for any suggestions.
It's simply ${blurb["organization${entity.customer.organization.name}Attire"]!}.
?interpret is only needed if you have a string that contains a piece of template. Besides you can't call directives (<#...>, <#...>) inside an expression.
I have a xml file, which i need to modify from my ruby script and save it. xml file looks something like
`

I need to replace <mtn:ttl>4</mtn:ttl> with <mtn:ttl>some other value</mtn:ttl> which comes under <mtn:test-case title="Train-Consist-Message"> and save it.
I have written below code, but its replacing all occurances of <mtn:ttl>4</mtn:ttl>.
`doc = IO.read(ENV['CadPath1']+ "conf\\cad-mtn-config.xml")
doc.gsub!(pattern, str)
File.open("File path", "w"){|fh| fh.write(doc)}`
Please help me with this. Waiting for your early reply...
String#gsub! modifies the string in-place, replacing all instances with the replacement specified. If you only want to replace the first instance, use String#sub or String.sub!.
The suggestion from Mike about using sub instead of gsub is good. But parsing XML (and HTML) with regular expression is usually frowned upon.
From your question I assume that you locate the to-be-modified element in terms of parent-child relations, not in terms of the source code order (i.e. you will not be able to say: "modify the second occurrence of this pattern"), so inventing a reliable regular expressions may be very, very hard.
You should use a parser library to find the element you want to change. There is a pretty large collection of those. See some of them at http://ruby-toolbox.com/categories/html_parsing.html and pick one, or use a built-in REXML library.
Alternatively, you could use a very simple 'html-scanner' module, which is included in Rails' ActionController (action_controller/vendor/html-scanner.rb), but if you do not use Rails, I am not sure whether extracting it is worth your time.
The exact code will depend on the parser you choose. Usually they have pretty good documentation/tutorials, so I am sure you will be able to handle it.
