Top Forums Shell Programming and Scripting sed to do replace on line above Post 302580950 by toptiger on Sunday 11th of December 2011 09:51:42 AM

Ok, say I have this piece of XML:

Code:
<TERM>
<PARAM NAME="DATACENTER” OP="EQ"
VALUE="Data1"/>
<PARAM NAME="GROUP” OP="EQ” VALUE="GRP_04"/>
</TERM>
</TERMS>

I need to find <PARAM NAME="GROUP” OP="EQ” VALUE="GRP_04"/>

but update VALUE="Data1"/> (i.e. the line above)

I specifically have to only have to update:

VALUE="Data1"/> when it is followed by <PARAM NAME="GROUP” OP="EQ” VALUE="GRP_04"/>
, because there are many instances of VALUE="Data1"/> that I do want to update
in the XML, does that make sense?

in short I need to have a command to replace the line above my search string

xml_parse - Start parsing an XML document

SYNOPSIS
int xml_parse (resource $parser, string $data, [bool $is_final = false]) DESCRIPTION
xml_parse(3) parses an XML document. The handlers for the configured events are called as many times as necessary. PARAMETERS
o $parser - A reference to the XML parser to use. o $data - Chunk of data to parse. A document may be parsed piece-wise by calling xml_parse(3) several times with new data, as long as the $is_final parameter is set and TRUE when the last data is parsed. o $is_final - If set and TRUE, $data is the last piece of data sent in this parse. RETURN VALUES
Returns 1 on success or 0 on failure. For unsuccessful parses, error information can be retrieved with xml_get_error_code(3), xml_error_string(3), xml_get_current_line_num- ber(3), xml_get_current_column_number(3) and xml_get_current_byte_index(3). Note Entity errors are reported at the end of the data thus only if $is_final is set and TRUE. PHP Documentation Group XML_PARSE(3)
