Remove the value ASCII 0-31 of the text

Hi all

I am trying to create an xml using the function of xmltype and for some reason, he throws a parse error and finally I realized that it is because the data linl (Ascii character 16) escape character.

So I want to delete the values 0 to 31 of my text ASCII before converting to XML. What is the best way to accomplish this task?

Thank you
VJ

Go to the suggestion of Damorgan, you could do something like this:

Connected to Oracle Database 11g Enterprise Edition Release 11.2.0.1.0
Connected as FSITJA

SQL>
SQL> with tab as (
  2  select to_clob('ABCDEFG' || chr(23) || chr(15) || 'HIJKL') x from dual)
  3  -- end of sample data
  4  select regexp_replace(x, '[' || chr(1) || '-' || chr(31) || ']') replaced_clob
  5    from tab;

REPLACED_CLOB
--------------------------------------------------------------------------------
ABCDEFGHIJKL

SQL>

The only thing is that if your CLOB is greater than 32 k it will be truncated, you may need to browse its length or something to that effect.

  • Remove the text/toggles between Images w/Tap

    I have a title page of an article composed of a photo with the text above it.  I want the user to be able to touch the screen to remove the text in order to allow them to view the photo itself.

    Is there a way to put the text on another layer, and then make sure that the layer disappear / reappear with one tap (like Mag +)?

    I tried a workaround using the sequence of images and slide shows of two images, one with and one without the text.  Using the slide show, I can allow the user to access and 'remove' the text showing them the underlying image without the text, but then they are blocked on this image and unable to return to the image with text/title.

    Anyone has any ideas, how to proceed?

    Thanks in advance!

    I want to change the State of object whenever the user touches the photo.  With a slide show if "Stop at the last frame" I the user cannot return to the original image.   If I don't check "Stop at the last frame" then it will automatically return to the first image - even if the user wants to stay put.

    Any ideas?

    It's simple.

    Create your 2 MSO steps using the State of the object Panel.

    When you select the DSO. The overlay creator Panel Slidshow controls.

    Leave it as what!

    Then, draw a rectangle on the ASM, select it and convert to button (object > Interactive > convert to button).

    In the buttons Panel, set the action of the button to go to the next State.

    Now use the preview at the bottom of the overlay button creator or panels Folio Builder to test the result.

    Each tap (click) will toggle the State currently displayed, that is, if I'm not wrong, what you asked.

    See in this sample file.

  • Numbers: How can I remove the text proposals?

    Hello

    I would like to erase or remove certain entries in the text proposals that I get, when you enter a value.

    I looked around caches & prefs, but so far I could not find anything...

    Best regards, Stefan

    I think you mean "semi-automatic", where number makes suggestions based on the values that it finds in the cells above the column in which you enter data.  Numbers shows the values you already entered above in this column.  For example, you could change those in cells above.

    Otherwise, you can format cells on the Shortcut Menu and explicitly enter the values you want to choose from the context Menu.

  • HP Elitebook 8740w: How can remove the text / name of the company that is displayed during the boot process?

    Hello

    I bought my work laptop from my employer. During the startup of my employer's legal name is still displayed on the splash screen ' "(the screen with the HP logo).

    -J' already started back and ran the EREPLOGO. EXE utility to remove the logo (ereplogo.exe/e). The utility said that the logo has been removed;

    -in the BIOS 'view custom logo' is unchecked, so it will not use an image of the partition tools hp;

    However, during the startup the company name is still displayed on the top of the screen... :-(

    (1) how can I change this text to start or remove it completely?

    (2) what can I do to display the specifications of hardware during startup instead of this "splash screen"?

    Thanks in advance,

    PS I have the latest BIOS (F.60 Rev.A, November 30, 2015)

    Hello

    I managed to change the line of text with the BiosConfigUtility64.exe.

    With "BiosConfigUtility64 getconfig:config.txt", you can write all the values in the bios and a text file with "BiosConfigUtility64 setconfig.config.txt", you can set all the values after you change the values you want to change. In my case, that I had to change the value of "property tag", which is the value that appears in the home screen during the boot process.

    Later, I discovered the tag 'property' can also be changed under the Security tab of the configuration of the BIOS (F10) normal... until I knew what the property tag, I associate the line of text to security so I did find the text before :-) field

  • How to remove the text areas of a scanned document

    How can I remove a plethora (sp?) of the text areas of a scanned document?

    Hello JBreeden,

    More scanned documents cannot be changed, unless you have a software that can read digital information. The scanned document is just a picture of the item that you have scanned. You must have a software like OCR (optical character recognition) to be able to make changes to the digitized item.

    This depends really on what type of Member of text that you used, but in general, you should select the sprite on the stage, then go to the Sprite of the property inspector tab.  Find the ink setting and change into Transparent or Matt.
