Hello. I use LR 5.2.2. I defined a structure "NEWS_ENTRY":

1<root>
2 <dynamic-element name='my-title' type='text' repeatable='false'></dynamic-element>
3 <dynamic-element name='my-content' type='text_area' repeatable='false'></dynamic-element>
4</root>

I created a new article with this structure, and I want to modify Asset Publisher portlet to show my field "my-title" instead of the article's default title (aka "name"). I looked through asset_publisher/display/abstracts.jsp and figured out that I have access to JournalArticleResource and JournalArticleDisplay for accessing to my article, but I can't understand how can I get article's "my-title" or "my-content" fields. How can I access them?

Thank you in advance!

I found that in JournalArticle database table there is a field content, which contains my structured data:

1content: <?xml version="1.0" encoding="UTF-8"?>
2
3<root default-locale="en_US" available-locales="en_US,ru_RU">
4 <dynamic-element instance-id="KaDPW0bZ" name="my-title" type="text">
5 <dynamic-content language-id="en_US"><![CDATA[Beginning of sales]]></dynamic-content>
6 </dynamic-element>
7 <dynamic-element instance-id="2MjsoV2D" name="my-content" type="text_area">
8 <dynamic-content language-id="en_US"><![CDATA[<p>Beginning of sales!!!</p>]]></dynamic-content>
9 </dynamic-element>
10</root>

Also, there is a field structureId: NEWS_ENTRY. So, I think i should get that content, structureId and pass them to some function, which will return me a Map with values of the keys. Is this possible or how can I get that fields (my-title and my-content) ?

Andrey, if you have acces to article xml and know which fields you want to extract and display,
use XPath expression to get value of those elements.
However I am not sure whether I gave the answer you need, may be your question is more specific to AssetPublisher portlet.

Hello, Victor. Thank you. I've solved my problem as you suggest:

1 JournalArticle journalArticle = JournalArticleLocalServiceUtil.getArticle(
2          articleResource.getGroupId(), articleResource.getArticleId());
3 myContent = journalArticle.getContentByLocale(languageId);
4
5 Document document = null;
6 try
7 {
8       document = SAXReaderUtil.read(new StringReader(myContent));
9       Node node = document.selectSingleNode("/root/dynamic-element[@name='my-title']/dynamic-content");
10       if (node.getText().length() > 0) {
11          title = node.getText();
12       }
13 }
14 catch (DocumentException e)
15 {
16       e.printStackTrace();
17 }

That's a good piece of code you made Andrey, now I know how to do it myself too. (I am using XOM library, so never did it this way)

When following that post, there are a few questions arising in my mind:

where do I have to put that piece of code?
where do articleResource and languageId come from?
is JournalArticleLocalServiceUtil always available or do I have to include it somehow? the same question arises wth SAXReaderUtil
what datatype does myContent have?

I am grateful for any kind of help!
