Xtract

 

NAME

Xtract, XtractLazy – structured ‘grep’-like programs for XML documents  

SYNOPSIS

Xtract <pattern> [ file … ]
XtractLazy <pattern> [ file … ]  

DESCRIPTION

Xtract and XtractLazy are structured ‘grep’-like programs for XML documents, loosely based on the XPath and XQL query languages. Xtract takes an pattern and reads an XML file from a file or from the standard input and extracts information from the XML file and prints it on the standard output. XtractLazy does the same as Xtract but uses the lazy parser combinators instead of the normal parser combinators and a such works faster and uses less memory than Xtract.
