Read elements of a xml file??????
Hi,
What is a good way to read elements of an xml file? i did try xmllint it doesnt provide a function to output values of a tree. In the below example when i specify from Family2 I need the name of the father then the output should be DAVE. Appreciate any help provided in this regards.
Many thanks.
for instance:
Quote:
Family1 ---> Father----->JOHN
Family1 --->Mother----->ANN
Family2 ---> Father----->DAVE
Family2 ---> MOM----->LISA
<TREE>
<Family1>
<Father>
<name = John />
</Father>
<Mother>
<name = ANN />
</Mother>
</Family1>
<Family2>
<Father>
<name=DAVE />
</Father>
<Mother>
<name= Lisa />
</Mother>
</Family2>
</TREE>

xmllint
xmllint(1) General Commands Manual xmllint(1)
NAME
xmllint - command line XML tool
SYNOPSIS
xmllint [--version | --debug | --shell | --debugent | --copy | --recover | --noent | --noout | --htmlout | --nowrap | --valid | --postvalid
| --dtdvalid URL | --timing | --repeat | --insert | --compress | --sgml | --html | --push | --memory | --nowarning | --noblanks | --for-
mat | --testIO | --encode encoding | --catalogs | --nocatalogs | --auto | --xinclude | --loaddtd | --dtdattr | --dropdtd] [xmlfile]
INTRODUCTION
The xmllint program parses one or more XML files, specified on the command line as xmlfile. It prints various types of output, depending
upon the options selected. It is useful for detecting errors both in XML code and in the XML parser itself.
It is included in libxml2.
OPTIONS
--version
Display the version of libxml2 used.
--debug
Parse a file and output an annotated tree of the in-memory version of the document.
--shell
Run a navigating shell.
--debugent
Debug the entities defined in the document.
--copy Test the internal copy implementation.
--recover
Output any parsable portions of an invalid document.
--noent
Substitute entity values for entity references. By default, xmllint leaves entity references in place.
--noout
Suppress output. By default, xmllint outputs the result tree.
--htmlout
Output results as an HTML file. This causes xmllint to output the necessary HTML tags surrounding the result tree output so the
results can be displayed in a browser.
--nowrap
Do not output HTML doc wrapper.
--valid
Determine if the document is a valid instance of the included Document Type Definition (DTD). A DTD to be validated against also can
be specified at the command line using the --dtdvalid option. By default, xmllint also checks to determine if the document is well-
formed.
--postvalid
Validate after parsing is completed.
--dtdvalid URL
Use the DTD specified by URL for validation.
--timing
Output information about the time it takes xmllint to perform the various steps.
--repeat
Repeat 100 times, for timing or profiling.
--insert
Test for valid insertions.
--compress
Turn on gzip compression of output.
--sgml Use the DocBook SGML parser. This allows documents written in SGML DocBook to be converted into an in-memory tree and treated as if
they were written in XML.
--html Use the HTML parser.
--push Use the push mode of the parser.
--memory
Parse from memory.
--nowarning
Do not emit warnings from the parser and/or validator.
--noblanks
Drop ignorable blank spaces.
--format
Reformat and reindent the output.
--testIO
Test user input/output support.
--encode encoding
Output in the given encoding.
--catalogs
Use the catalogs from $SGML_CATALOG_FILES. Otherwise /etc/xml/catalog is used by default.
--nocatalogs
Do not use any catalogs.
--auto Generate a small document for testing purposes.
--xinclude
Do XInclude processing.
--loaddtd
Fetch external DTD.
--dtdattr
Fetch external DTD and populate the tree with inherited attributes.
--dropdtd
Remove DTD from output.
