Numbering and Bulleting In MS Word 2007 docx format

This explains the logic behind Numbering and Bulleting in Docx format.
Important files.

1. document.xml inside folder /word
2. numbering.xml inside folder /word

Inside document.xml you find tag like this


.......................


.......................




.................

Here tag is important , this refers to the information about number or bullets.
Inside numbering.xml you will find tags:

..............

......




Follw0ing three links plays role: <
1. From document.xml//w:p/w:pPr/w:numPr/w:numId/@ w:val
links to
numbering.xml/w:num/@w:numId
2. From numbering.xml/w:num/w:abstractNumId/@w:val
links to
numbering.xml/w:abstractNum/@ w:abstractNumId
3. From document.xml//w:p/w:pPr/w:numPr/w:ilvl/@w:val
links to
numbering.xml/w:abstractNum/w:lvl/@w:ilvl
Seems little trick but well linked.
document.xml has links to and to be selected , while numbering.xml has link to which to be selected.
One more thing, numId in numbering.xml starts from 1 while w:abstractNumId starts from 0.
For any issue not understood , please feel free to mail me.

To check type of variable in XQuery

XQuery has a very easy way to check type of variable same as Java.

Use
$variable instance of 'type'
where 'type' can be
xs:string
xs:date
or any type you want to check.

Search Using Grep

1. grep -r "keyword" .
here we are searching for the word "keyword" , in current directory and sub-directories.
This will return the list of files and lines which contain this word.
2. grep -lr "modules" .
This will return only list of files .
3. grep -lr "mod.*" .
grep also supports regular expressions

General tag : grep "options" "keyword" "drive specification"

Where options are:

-a All disks.
-c Show the matched characters in Colour.
-f List the File name.
-h Hard disks only.
-i Make the pattern case Insensitive.
-n List the line Number.
-o Only list the file name.
-s Subdirectories.
-x List the lines which do NOT have the pattern in them.

There are many more options , to explore use:
grep man

Installing Java 1.5 on linux 64-bit Machine

1. Download jdk from here:

http://cds-esd.sun.com/ESD39/JSCDL/jdk/5.0_15/jdk-1_5_0_15-linux-amd64-rpm.bin?AuthParam=1212502176_37e9eeebbc1a57c5c24004ebc6ec106c&TicketId=nodzBV0QRXZwluEqlUWeV5ubcQ%3D%3D&GroupName=CDS&FilePath=/ESD39/JSCDL/jdk/5.0_15/jdk-1_5_0_15-linux-amd64-rpm.bin&File=jdk-1_5_0_15-linux-amd64-rpm.bin
(Note: Don't confuse by the name amd64 here , this version is for intel also)

2. At the promt window : Enter :su
3. Enter the root password.
4. Change to the directory in which you want to install.

Type: cd directorypath

5. Change the permission of the file to make it executable.

Type: chmod a+x jre-1_5_0_02-linux-amd64-rpm.bin
6. Verify that you have excutable permission on the file.

Type: ls -l
7. To start the installation process,

type:. /jre-1_5_0_02-linux-amd64-rpm.bin

8. License agreement will be displayed. Press the spacebar to display the next page. At the end, enter yes to proceed with the installation.
9. The installation file creates jre-1_5_0_02-linux-amd64.rpm file in the current directory.
Run the RPM command at the terminal to install the packages.

Type: rpm -iv jre-1_5_0_02-linux-amd64.rpm
The JRE is installed in jre1.5.0_(version number) sub-directory under the current directory.

Useful Linux Commands

Installing Java:
1. chmod 744 jre-1_5_0_15-linux-amd64-rpm.bin

java is intalled.
Now to make it active do following:
1. edit .bashrc
2. add PATH=$PATH:/usr/local/bin
where /usr/local/bin is the pate where java is installed.
If you dont want to edit Path variable than create symbolic link (ln) in directory /usr/bin for java, javac , and other utilities you want to use of jre.
