Filtering an HTML file

I have a requirement to be able to take an HTML file, parse it, and filter it so that I can automatically change the src attributes on image elements. Does anyone have any code to do anything like this in a simple way?

I took a look at Tidy, but couldn't find enough good documentation (read examples) to figure out what to do. Seems like it converts everything to DOM, and then I need to convert this all back into HTML. I think this is a lot of work, any examples?
As for Regex's, is this a safe thing to do? Seems like there are many things that could go wrong. Again, anyone have any simple examples for how to do things this way?
To reiterate my problem, I have an HTML file sitting on a disk. I'd like to convert it so that anything that looks like this:
<IMG height=1 alt="" src="files/blank.gif" width=1 border=0>
gets converted to:
<IMG height=1 alt="" src="myservlet?file=files/blank.gif" width=1 border=0>
Where the actual thing being substituted may depend on what was there before. This is a simplified example of a bigger problem, so a stand alone piece of code in Perl, etc. won't help me. Thanks for any help you can give.

How can I change the font in html-file

Hello,
if I create a new html-file in KM-Content - Folder - New - Html-File, I always get the font Times New Roman. In the editor I have Arial oder something similar - but not in the view.
Does anybody know how to change this font to Arial? Where do I have to configure what? Thanks

Susanne

sorry that I´m no mathematician or a SAP EP-consultant
Never mind!
So "dumb" is maybe the wrong word
You didn't realize the ";-)" behind it?!
It's just that this strict "it doesn´t work like you wrote" was a bit irritating, in fact it works, it's tested on the same version as you are on, and it's also not a very new feature (new features often are buggy at some ends).
But now I had a second look on the link I have given - and sorry, even if it should help, in fact it was the EP50-version. The NW04 version, which seems you have already detected by yourself, is http://help.sap.com/saphelp_nw04/helpdata/en/a8/923717bc40dd49b1e296b9877e98f0/frameset.htm
After having seen this, I also found this ominous description of "HTML Filter for Portal Stylesheets"http://help.sap.com/saphelp_nw04/helpdata/en/cc/b8f941db015f24e10000000a1550b0/frameset.htm
Yes, this does in fact not exist on EP6 SP9. You could open an OSS message and ask to delete the description of a non-existing feature or for delivery of it.
Anyhow, it shouldn't do more than the HTML Stylesheet Filters are already doing - maybe it would choose the corresponding CSS by itself?
Is there anything else I have to configure anywhere?
The prerequisity is "The publishing pipeline is configured appropriately.", but this should be the case by default.
The repository used is "documents" and the html file you have been using is stored in this repository?
The stylesheet exists on the location set within the stylesheet configuration?
There are not sooo many screws to turn...?!
Hope it helps

View metadata near his image in a html file?

Hi
I am new to this board,
I wanted to ask if there is a way to publish the metadata of an image, (or filtered metadata), into a html file, (for expample near the image).
It want to publish photos with some of the metadata of it made readable on an easy way...
Thank you in advance for looking at my problem
Erwin

Within Bridge you can select a batch of images and convert them to a Photoshop Web Photo Gallery.
You can customize the page templates that Photoshop uses. I've not seen any documentation for metadata but some of the templates display caption, copyright, etc. Try searching or asking on the Photoshop forum.

<html:file property="fileupload" size='25' value="sample.xls" onchange="callsheet()" />

Two points -
1) Java is not Javascript or HTML; you would do better to find a more appropriate forum.

How can I edit an html file in Firefox using View Source?

I have created an html webpage and saved it to my pc. I can't edit the html file in firefox when I right click on the page and select "View Source". I can view the code but I can't edit it. I can do this in IE9.
I thought I was able to do this before in Firefox.
Did my settings change somewhere that I can no longer do this?
Do I have to have something checked in the Web Developer extensions for it to work?
I'm using Firefox 24.0
Thank you for any help with this. :)

The View Source window in Firefox cannot be used to change computer codes. Nor can the Web Developer tools.
Sorry for any inconvenience.
I suggest using Programmer's Notepad.

Relative path for HTML file

Hi ,
This is my requirement. In the ESS Personal information overview page, I can add a HTML file to the additional information section.
I have created a HTML file by creating a web module and enterprise application and deployed the same through NWDI.
I declare a resource wher ei mention the path. Here i specifed the complete path of the html file ... like
http://hostname:portname/addinfo/addinfo.html. Which i know is a wrong thing to do since when i move the html filel to the production system it will still be accessing the html file in the dev system.
How do i give the relative path here so that the html file accessed is from the production system when we go-live.
Please suggest.
regards
sam

Hi,
One simpler solution is to use an AppIntegrator iView, as explained in the weblog <a href="https://www.sdn.sap.com/irj/sdn/weblogs?blog=/pub/wlg/2786">Integrating your Web Front-ends into the SAP Enterprise Portal using the Application Integrator</a>. It worked well for us.
You can remove the user authentication part in the portalapp.xml if you don't need it.

How to generate & publish webhelp html files in different folder than default folder

Hi All,
I am new to robo help. I have a requirement to generate & publish webhelp html files in a different folder than default folder.
Could anyone please tell me the steps to change the folder
Thanks
Rashmi

You change the generate folder and filename in the first field on the first page of the wizard. It must be a folder on your hard disk.
You change the publish folder in the last page of the wizard. Anywhere you like.

Importing/adding html files with bookmarks to project/TOC

Overview:
I've been importing some old html files that have a massive number of bookmarks/anchors in them (few hundred html 'pages' some of them mini help document libraries) in an effort to move the manuals into RH format. Using RH11
Problem:
when I import them all the bookmarks are showing up under each topic page. Second, when I add a folder into the TOC or auto generate a TOC it pulls each bookmark as a page (see screen shot). Any way I can get around this issue? I can manually add (drag/drop) the 'updates' page here into the TOC and it doesn't pull the bookmarks as pages. However i'm interested in knowing if I can simply not import the bookmarks or exclude them from populating as pages in the TOC. This seems to be new to RH11 (i've used RH9 without this issue in the past, on a similar project).
System;
RH11
Office 2013
SharePoint 2010
Thanks

Hi there
Note that when you choose to auto-generate a TOC, you have a choice as to whether to create links to bookmarks. Look at the dialog below:
My guess is that in the older version this option wasn't enabled when you auto created a TOC and you really didn't pay attention to the way it was set in the new version.
Cheers... Rick

HTML file is not being shown properly in the JEditorPane

Hi,
I am using JEditorPane to display an HTML file from the local disk. This HTML file contains the html tables. Now when this file is getting displayed in the JEditorPane, one top row grid is not being displayed in the editor pane. content of the row is there...but the column grid is missing. All other rows and columns are being shown but the first row-column grid which contains the heading for column.
Also when I m printing the content of this JEditorPane using Java Print API then no grid is being printed on the paper. content is coming properly but no table grids. when i have taken the print out of the original html file from the browser then table grids are being printed out properly.
Please do help me out in showing the HTML file in the JEditorPane properly and printing the same.
Many Thanks,
gshankar

Hi,
JEditorPane renders HTML with many limitations.
You can use JDIC for the same. refer: jdic.dev.java.net
But JDIC does not work on windows 98.

Getting links and its names from a html file

Hi everyone
My problem about the a getting links with name from a html file. For example
İn a web page in this site ?SUN? when use click SUN the browser open http://java.sun.com
İ want both of them, so the links and name. I can succeeded the get link but i don t know how to get the link name.
For example :
<B>setRightComponent(Component)</B>
İn this code segment i want to get B tag. But how i don t know. To get A tag i used this code
List result = new ArrayList();
try {
// Create a reader on the HTML content
URL url = new URI(uriStr).toURL();
URLConnection conn = url.openConnection();
Reader rd = new InputStreamReader(conn.getInputStream());
// Parse the HTML
EditorKit kit = new HTMLEditorKit();
HTMLDocument doc = (HTMLDocument)kit.createDefaultDocument();
kit.read(rd, doc, 0);
// Find all the A elements in the HTML document
HTMLDocument.Iterator it = doc.getIterator(HTML.Tag.A);
while (it.isValid()) {
SimpleAttributeSet s = (SimpleAttributeSet)it.getAttributes();
String link = (String)s.getAttribute(HTML.Attribute.HREF);
if (link != null) {
result.add(link);
it.next();
İ can use B tag but i don t know hot to get its value because it has no prefix such as HREF....
i am sorry if i use a bad explanation style or incorrect word.

            System.out.println( href + " : " + text );

How Do I Use the Help Tag/Help Path in LabVIEW to Link to a Specific tag in an HTML File?

Is there any way to point user to a tag in an HTML file when he click "Click here for more help" ?

George,
I believe you are correct in saying that there is no way to link directly to a specific anchor tag within an html file from the context help.
I would encourage you to visit our Product Suggestion Center if this is a feature you would like to recommend that our R&D team consider for future versions of LabVIEW.
Is it possible for you to create a .chm file? Or perhaps you could have some kind of "table of contents" at the top of your .html help file. This would require an extra click by the user but may be an option for you.

Multiple HTML-files in one stack / link another HTML-file in a stack

Hi,
I want to integrate a webapp (html/js) into a stack of a dps-folio. All the HTML works fine ... all no problem, but at clicking the first link on the initial HTML-document the next (local) HTML-File is opened in a slider with a "ready"/"Fertig"-bar at the top. But I want, that all html files are seamlessly loaded in the same view.
At this point i found: http://help.adobe.com/en_US/digitalpubsuite/using/WS67cb9e293e2f1f60-8ad81e812b10bfd837-80 00.html and i made the file "NativeOverlays.config" and moved it to the described location. After that, the behaviour was correct in the desktop-preview-app of the DPS, but it still fails on the iPad-Adobe-Viewer.
How can i link between HTML-files without any interuption or sliding?
Thank you!
Christian

Hi Tim,
Thanks for replying. I have looked for "PDFBookBinder class" in xml publisher user guide for ver 5.6.2. I didn't get any reference of this text. Can you please guide me to a tutorial/link where i can get more information about this class.
Also, i originally thought of similar to your second logic, as my design basis. Oracle process generates the xml file in output directory which i can get. What i didn't get is how do i "pick them up and merge" using publisher. Also, is there way to do this merging process using pl/sql ? Can you please give little more information on your second approach.
My original plan of action is that i will create a report set in which i will call oracle seeded report for all 7 payrolls in a sequential manner. Then using the child requests of the report set i will get to 7 xml files generated by seeded oracle process. Then the piece i am not sure of , i will use those 7 files to generate a single xml file having payroll name as tree top for each output. Once single xml is ready, i can easily design a template and register the process to generate output as Excel.This process will not require me to actually change any data or do any calculation. It will only reformatting the feilds we see and abiity to see all 7 payroll at one time rather then entering these numbers manually into an excel to do analysis.
Please provide your feedback, if you think above plan is not feasible or need corrections.

Elements do not show up in edge file but they do in HTML file; no errors occured

I am a senior in college working on building a website for a fictional company for a year-long thesis graphic design project. In my class last semester, I learned how to use Edge Animate and created an 11 page website without any trouble. I had always kept the files saved to my flash drive, and kept a backup on my personal laptop as well as on my external hard drive. There was also a backup of the files on a disc that I turned into my professor in mid-December. All of these files worked fine at the time.
In early January, I wanted to make changes to the website so I installed a trial version of Edge Animate on my laptop. When I opened any of the edge files from any of the backups, the stage was blank and the animations did not show up on the timeline. The elements of the website still show up in the Library but they are no longer arranged on the stage. When I got back to school at the end of January, I tried opening the files on the school computers and had the same problem. I asked my professor to try the file that was saved to the disc and he encountered the same issues on his computer. All of these computers are either iMacs or Macbook Pros.
I have not recieved any error messages and did not do anything to corrupt the files or save over them. I am able to open the html files in a browser with no issues; all animations and images work fine. The only change I can think of is that Edge may have been updated over break and when I installed the trial version I installed a newer version, and for some reason the new version of the program could not properly load my project that I started on a older version in October or November of 2013.
I am happy to upload the files but I am unsure how to do that. Please let me know if there is a way to resolve this issue, or will I have to start over?
Thank you!

Try to clear your preference and restart your Animate.See if that fixes your problem
http://helpx.adobe.com/edge-animate/kb/restore-preferences-edge-animate.html
If that does not work see if there is a lloopback address lookup.
Check out the correct answer in this post to fix that http://forums.adobe.com/message/6116991

My imported backup html files from another computer do not show up after import

I am currently transferring files from my macbook pro to a pc netbook. I already exported my firefox bookmarks via an external drive and accessed the html file on my new netbook. After importing the html on firefox on my new netbook, the bookmarks do not show up on my bookmark list.

Please see this article on how to move your bookmarks and settings from one computer to another: [[Moving your Firefox bookmarks and settings]].
Caution: Restoring bookmarks from a backup will overwrite your current set of bookmarks with the ones in the backup file.
