xslt - XSL test for populated field -

-

Is there a text that I can use to check that a field is populated and the field's display based on the result Toggles?

You can test this kind of existence for the existence of an element: 

  & lt; Xsl: if test = "/ root / parent / node" & gt; Prints and if only the expression is present then & lt; / Xsl: if & gt;

If you know that the element exists and you still have one value after that, use it: 

  & lt; Xsl: if test = "string-length (/ root / parent / node)> 0" & gt; Print that expression has a non-empty value & lt; / Xsl: if & gt;

CPU 99% waste and output window VS Shows things associated with compiling it. Is there any way to fix this? It does not make any sense. It is not necessary to upgrade that we are a viable alternative to those people who have to deal with the legacy code. Did you try to upgrade SP1? I do not know of any specific problem in this area, but this will be the first change I tried to do.

I am trying to install Ubuntu on a USB, the problem is that I do not want to repeat the boot once, I want to keep my windows, but I want to boot Ubuntu using the virtualbox and USB to the Ubuntu Want to use my hard drive, but how? The virtualbox will not recognize USB as a hard drive when installing an ISO In virtualbox, you have to create a virtual hard disk. Make a USB drive and tell the virtual box to install a virtual hard drive that you just created. EDIT: To answer some more questions: In the new Virtual Disk dialog, click the button next to the location field, click on the button Virtual Disk on Flash Drive To access, click the arrow next to Save in the Select File in the window next to Save In, and you can access your flash drive from there. I recommend setting the image to be allocated dynamically, because the size of your flash drive is not available disk space.
