XML search and replace

I have an XML document with the following dates and periods.  It is run twice a month.

An example of the lines are as follows:

<DOC_REC_DT_DC Attribute="Y"><![CDATA[2013-10-15]]></DOC_REC_DT_DC>
<DOC_PER_DC Attribute="Y"><![CDATA[1]]></DOC_PER_DC>
<BFY Attribute="Y"><![CDATA[2014]]></BFY>

There are about 10 different dates that have to be changed and each of these lines are in the document an unknown number of times.  For example, doing this manually, I find the first occurrence of <DOC_REC_DT_DC... and replace all with the same text except for changing the date from 2013-10-15 to the current date.

I would like to automate this so it doesn't have to be done manually.

I don't know xml so I'd like to use a batch file or some reliable utility.

Thank you for your help.

I would suggest using a text editor like Programmer's Notepad (www.pnotepad.org) and use the built-in regular expression functionality in the Search/Replace.

If all dates in the document need to be replaced with the current date, you can use this search pattern:

\d{4}-\d{2}-\d{2}

Enter the current date in the replace field and all instances of a date in the format of YYYY-MM-DD will be replaced with the current date.

If there are dates that should not be changed, in addition to those that should, then you want to use a more specific search pattern:

e.g.,

Search Pattern
(<DOC_REC_DT_DC Attribute="Y"><!\[CDATA\[)\d{4}-\d{2}-\d{2}

Replace Pattern
\1<current date>    

(replace "<current date>" with the actual date value)
