I have string like as follow, which is generated in mvc controller and display in a view within a table cell. S020050A,S020050B,S020050C,S020050D,S020050E,S020050F
,S020050G,S020050H,S020050I,S020050J,S020050K,S020050L
As I want to wrap the text on every 5 words, I have pushed
tag on every 5 words, so that string look like as follow
S020050A,S020050B,S020050C,S020050D,S020050E,S020050F
,S020050G,S020050H,S020050I,S020050J,S020050K,S020050L
I am intended to break the line from there, but in a view it just shows as it is, tag not interpreted as new line but simply as a part of string
I tried putting Environment.Newline and /n as well, when I did this in simple html page, it worked, so I believe it asp.net own mechanism which suppress tag, how I can make tag interpreted as new line?
I could solve it, from controller code (back end) add -> \n instead where you want line break and then in view use this style ->
style="white-space: pre-line"

I am generating Word docs from html. Basically, I build a file with html and save it as a .doc. Then I open it in Word and apply a template. All good so far.
I would like to automatically generate a custom TOC via the HTML ie when I am building the document. I need to insert a field code to do that, in the same way I do to add page numbering via the HML. eg:
<span style="mso-field-code: PAGE " class="page-field"></span>
If I save my html doc as docx and apply a template, I can make a TOC based in the styles in the way one would normally create a TOC in Word. I customised the TOC so the Title style is the top level followed by H1, H2 then H3. If I then toggle the field code on the TOC, the field code looks like this:
{ TOC \t "Heading 1,2,Heading 2,3,Heading 3,4,Title,1" }
Now, I can add HTML like this to insert the TOC:
<div style="mso-field-code: TOC " class="toc-field">TOC goes HERE</div>
When I do that, if I right click the text "TOC goes HERE" I get the option to "Update field" and if I do that a TOC is generated using the default H1,H2,H3 tags.
But, what I can't work out is how to include the
\t "Heading 1,2,Heading 2,3,Heading 3,4,Title,1"
part so my custom style sequence is applied. I have tried all sorts of combinations and it seems that adding anything after TOC causes Word to not make a field code.
Does anyone have any suggestions?
Update:
Based on the essential help from #slightlysnarky below, I thought I would summarise the outcome here because the information I needed was in a Microsoft chm file that was taken down many years ago. If you read the following extract from that help manual and compare it to the solution below you will see how this all works.
Word marks and stores information for simple fields by means of the Span element with the mso-field-code style. The mso-field-code value represents the string value of the field code. Formatting in the original field code might be lost when saving as HTML if only the string value of the code is necessary for its calculation.
Word has a different way of storing field information to HTML for more complex fields, such as ones that have formatted text or long values. Word marks these fields with so the data is not displayed in the browser. Word uses the Span element with the mso-element: field-begin, mso-element: field-separator, and mso-element: field-end attributes to contain the three respective parts of the field code: the field start, the separator between field code and field results, and the field end. Whenever possible, Word will save the field to HTML in the method that uses the least file space.
So, basically, add tags as shown below to your HTML at the point you wish the TOC to appear.
:-)
Word recognises a "complex field format" in HTML, along the same lines as it does in the Office Open XML format. So you can use
<span style='mso-element:field-begin'></span>TOC \t "Heading 1,2,Heading 2,3,Heading 3,4,Title,1"
<span style='mso-element:field-separator'></span>This text will show but the user will need to update the field
<span style='mso-element:field-end'></span>
This construct is outlined in a Microsoft document called "Microsoft Office HTML and XML Reference". It's a Windows .exe that unpacks to a .chm Help file. You can get it here
The info. on encoding fields is in Getting Started with Microsoft Office 2000 HTML and XML->Microsoft Word->Fields
There may be a later version but that's the only one I could find.
I have a problem which is probably trivially easy but I can't seem to get it working. Using this post, I do a search using Regex in a text string to convert any links into html markup, but when it comes to display on the page it just displays like this:
this is link
<a href='http://www.google.com'>http://www.google.com</a>
In the view I have:
<p>#news.Body</p>
edit: great my question is now displaying how I want. So now to the actual question, how do I get the page displaying an actual link instead of the code when displayed to the user.
Use `` around your variable (e.g.)
Use "{}" icon in toolbar to insert code
Indent your code by one empty line, 4 spaces and leading empty line
E.g.:
Like this
You can edit this answer to see raw output
We are using s:property tag to display string value on struts 2.
<s:property value="stringValue"/>
If "stringValue" has multiple spaces then it is showing only 1 space instead of exact text.
Ex: String stringValue ="Hello World, Welcome";
Output: Hello World, Welcome.
Here string text has two space in between but on application it is displaying only 1 space.
I have tried to use escapeHtml as false but same issue.
What is wrong with this tag?
Best Regards,

Nothing is wrong with the tag.
HTML treats multiple whitespaces as a single whitespace; that's just the way HTML is.
If you want to explicitly have multiple spaces you'll need to convert them to entities. There are a zillion ways to do that.
HTML myHtml=new HTML(SafeHtmlUtils.fromString("<i>Test</i>"));
HTML myHtml2=new HTML("<i>Test2</i>");
testHTMLPanel.add(myHtml);
testHTMLPanel.add(myHtml2);
OUTPUT:
<i>Test</i>
Test2
The right output should be the formmatted text like the second one. Other Gwt html widget also have the similar problem.
I am using Eclipse Juno.
SafeHtmlUtils.fromString(String s)
HTML-escapes its argument and returns the result wrapped as a SafeHtml.
That means that you get somthing like .0;i&#.62;Test&#.60;&#.47;i&.#62;
Check
https://developers.google.com/web-toolkit/doc/latest/DevGuideSecuritySafeHtml
It's a security thing:
The reason why you have SafeHtmlUtils.fromString(userString) is that you can take a dynamic string, for example from a user input, and create a html text from it. It's more safe than just use Html.setText(userString) because with setText(userString) it would be feasible to inject vulnerable code.

I tried this, content.gsub("\r\n","<br/>") but when I click the view/show button to see the contents of these line, I get the output/result=>
set tabstop=4<br/> set shiftwidth=4<br/> set nu<br/> set ai<br/> syntax on<br/> filetype plugin indent on
But I tried to get those lines as a seperate lines. But all become as a single line. Why?
How can I make all those lines with a html break (<br/>) ?
I tried this, that didn't work.
#addpost = Post.new params[:data]
#temptest = #addpost.content.html_safe
#addpost.content = #temptest
#logger.debug(#addpost)
#addpost.save
Also tried without saving into database. Tried only in view layer,<%= t.content.html_safe %> That didn't work too.
Got this from page source

An alternative to convert every new lines to html tags <br> would be to use css to display the content as it was given :
.wrapped-text {
white-space: pre-wrap;
}
This will wrap the content on a new line, without altering its current form.
You need to use html_safe if you want to render embedded HTML:
<%= #the_string.html_safe %>
If it might be nil, raw(#the_string) won't throw an exception. I'm a bit ambivalent about raw; I almost never try to display a string that might be nil.
With Ruby On Rails 4.0.1 comes the simple_format from TextHelper. It will handle more tags than the OP requested, but will filter malicious tags from the content (sanitize).
simple_format(t.content)
Reference : http://api.rubyonrails.org/classes/ActionView/Helpers/TextHelper.html
http://www.ruby-doc.org/core-1.9.3/String.html
as it says there gsub expects regex and replacement
since "\n\r" is a string you can see in the docs:
if given as a String, any regular expression metacharacters it contains will be interpreted literally, e.g. '\d' will match a backlash followed by ‘d’, instead of a digit.
so you are trying to match "\n\r", you probably want a character class containing \n or \r -[\n\r]
a = <<-EOL
set tabstop=4
set shiftwidth=4
set nu
set ai
syntax on
filetype plugin indent on
EOL
print a.gsub(/[\n\r]/,"<br/>\n");
I'm not sure I exactly follow the question - are you seeing the output as e.g. preformatted text, or does the source HTML have those tags? If the source HTML has those tags, they should appear on new lines, even if they aren't on line breaks in the source, right?
Anyway, I'm guessing you're dealing with automatic string escaping. Check out this other Stack Overflow question
